In the first scheme, we present a new technique that uses only one group element to represent an attribute, while the existing ABE schemes of the same type need to use three different group elements to represent an attribute for the three possible values (namely, positive, negative, and wildcard). Our new technique leads to a new CP-ABE scheme with constant ciphertext size, which, however, cannot hide the access policy used for encryption. The main contribution of this paper is to propose a new CP-ABE scheme with the property of hidden access policy by extending the technique we used in the construction of our first scheme. In particular, we show a way to bridge ABE based on AND-gate with wildcard with inner product encryption and then use the latter to achieve the goal of hidden access policy. We prove that our second scheme is secure under the standard decisional linear and decisional bilinear Diffie–Hellman assumptions.

Attribute-Based Data Sharing Scheme Revisted in Cloud Computing
 
27:05
Ciphertext-policy attribute-based encryption (CPABE) is a very promising encryption technique for secure data sharing in the context of cloud computing. Data owner is allowed to fully control the access policy associated with his data which to be shared. However, CP-ABE is limited to a potential security risk that is known as key escrow problem whereby the secret keys of users have to be issued by a trusted key authority. Besides, most of the existing CP-ABE schemes cannot support attribute with arbitrary state. In this paper, we revisit attribute-based data sharing scheme in order to solve the key escrow issue but also improve the expressiveness of attribute, so that the resulting scheme is more friendly to cloud computing applications. We propose an improved two-party key issuing protocol that can guarantee that neither key authority nor cloud service provider can compromise the whole secret key of a user individually. Moreover, we introduce the concept of attribute with weight, being provided to enhance the expression of attribute, which can not only extend the expression from binary to arbitrary state, but also lighten the complexity of access policy. Therefore, both storage cost and encryption complexity for a ciphertext are relieved. The performance analysis and security proof show that the proposed scheme is able to achieve efficient and secure data sharing in cloud computing.

Server Aided Public Key Encryption with Keyword Search
 
09:33
Server-Aided Public Key Encryption With Keyword Search Abstract: Public key encryption with keyword search (PEKS) is a well-known cryptographic primitive for secure searchable data encryption in cloud storage. Unfortunately, it is inherently subject to the (inside) offline keyword guessing attack (KGA), which is against the data privacy of users. Existing countermeasures for dealing with this security issue mainly suffer from low efficiency and are impractical for real applications. In this paper, we provide a practical and applicable treatment on this security vulnerability by formalizing a new PEKS system named server-aided public key encryption with keyword search (SA-PEKS). In SA-PEKS, to generate the keyword ciphertext/trapdoor, the user needs to query a semitrusted third-party called keyword server (KS) by running an authentication protocol, and hence, security against the offline KGA can be obtained. We then introduce a universal transformation from any PEKS scheme to a secure SA-PEKS scheme using the deterministic blind signature. To illustrate its feasibility, we present the first instantiation of SA-PEKS scheme by utilizing the Full Domain Hash RSA signature and the PEKS scheme proposed by Boneh et al. in Eurocrypt 2004. Finally, we describe how to securely implement the client-KS protocol with a rate-limiting mechanism against online KGA and evaluate the performance of our solutions in experiments.

Charm: A Framework for Rapidly Prototyping Cryptosystems
 
01:05:07
Over the past decade the cryptographic research community has made impressive progress in developing new cryptographic protocols. This work has advanced our understanding of basic technologies such as public key encryption, key agreement, and digital signatures. Moreover, it has given us entirely new paradigms for securing data, such as Attribute Based Encryption, anonymous credentials and techniques for computing on encrypted data. Despite these advances, only a trickle of new cryptographic technology has filtered down to the systems community in the form of useable cryptographic implementations. Even supported prototype research implementations are few and far between. This is a major loss for researchers, to say nothing of industry and the open source community. In this talk we introduce Charm, an extensible Python-based framework for rapidly prototyping cryptographic systems. Charm was designed from the ground up to support the development of advanced cryptographic schemes. It includes support for multiple cryptographic settings, an extensive library of re-usable code, along with the infrastructure necessary to quickly implement interactive protocols. Our framework also provides a series of specialized tools that enable different cryptosystems to interoperate. This paper describes Charm and the various capabilities provided through our modular architecture. Through several examples, we show that our approach produces a potential order of magnitude decrease in code size compared to standard C implementations, while inducing an acceptable performance impact.

Functional encryption from LWE
 
55:59
Recent times have seen fantastic advances in the general area of "computing on encrypted data". Of particular importance, is the fast-growing area of functional encryption (FE). Functional encryption is a generalization of public key encryption which allows tremendous flexibility and control in learning information from encrypted data. In functional encryption, a user's secret key corresponds to some function f, denoted by SK f . The ciphertext corresponds to some input x chosen from the domain of f. Given SK f and ciphertext CT x , the user may run the decryption procedure to learn f(x). Security of the system guarantees that nothing beyond f(x) can be learned from CT x and SK f . We will study how lattices can be used for the construction of functional encryption schemes. Of special interest to us will be the "learning with errors" (LWE) assumption, which enjoys strong worst case guarantees that makes it very desirable for the construction of cryptographic primitives. We will review known constructions of functional encryption from LWE, including FE for point functions or "identity based encryption", FE for linear functions or "inner product" encryption" and FE for more general circuits or "attribute based encryption for circuits". We will also discuss some open problems in this fast growing area.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Broadcast encryption is the cryptographic problem of delivering encrypted content (e.g. TV programs or data on DVDs) over a broadcast channel in such a way that only qualified users (e.g. subscribers who have paid their fees or DVD players conforming to a specification) can decrypt the content. The challenge arises from the requirement that the set of qualified users can change in each broadcast emission, and therefore revocation of individual users or user groups should be possible using broadcast transmissions, only, and without affecting any remaining users. As efficient revocation is the primary objective of broadcast encryption, solutions are also referred to as revocation schemes. Rather than directly encrypting the content for qualified users, broadcast encryption schemes distribute keying information that allows qualified users to reconstruct the content encryption key whereas revoked users find insufficient information to recover the key. The typical setting considered is that of a unidirectional broadcaster and stateless users (i.e., users do not keep bookmarking of previous messages by the broadcaster), which is especially challenging. In contrast, the scenario where users are supported with a bi-directional communication link with the broadcaster and thus can more easily maintain their state, and where users are not only dynamically revoked but also added (joined), is often referred to as multicast encryption. The problem of practical broadcast encryption has first been formally studied by Amos Fiat and Moni Naor in 1994. Since then, several solutions have been described in the literature, including combinatorial constructions, one-time revocation schemes based on secret sharing techniques, and tree-based constructions. In general, they offer various trade-offs between the increase in the size of the broadcast, the number of keys that each user needs to store, and the feasibility of an unqualified user or a collusion of unqualified users being able to decrypt the content. Luby and Staddon have used a combinatorial approach to study the trade-offs for some general classes of broadcast encryption algorithms. A particularly efficient tree-based construction is the "subset difference" scheme, which is derived from a class of so-called subset cover schemes. The subset difference scheme is notably implemented in the AACS for HD DVD and Blu-ray Disc encryption. A rather simple broadcast encryption scheme is used for the CSS for DVD encryption. The problem of rogue users sharing their decryption keys or the decrypted content with unqualified users is mathematically insoluble. Traitor tracing algorithms aim to minimize the damage by retroactively identifying the user or users who leaked their keys, so that punitive measures, legal or otherwise, may be undertaken. In practice, pay TV systems often employ set-top boxes with tamper-resistant smart cards that impose physical restraints on a user learning their own decryption keys. Some broadcast encryption schemes, such as AACS, also provide tracing capabilities.

On the Security of Data Access Control for Multi Authority Cloud Storage System
 
03:02
On the Security of Data Access Control for Multi-Authority Cloud Storage System -- Data access control is an effective way to ensure the data security in the cloud. However, due to data outsourcing and untrusted cloud servers, the data access control becomes a challenging issue in cloud storage systems. Existing access control schemes are no longer applicable to cloud storage systems, because they either produce multiple encrypted copies of the same data or require a fully trusted cloud server. Ciphertext-Policy Attribute-based Encryption (CP-ABE) is a promising technique for access control of encrypted data. It requires a trusted authority manages all the attributes and distributes keys in the system. In cloud storage systems, there are multiple authorities co-exist and each authority is able to issue attributes independently. However, existing CP-ABE schemes cannot be directly applied to the access control for multi-authority cloud storage systems, due to the inefficiency of decryption and revocation. -- For More Details Contact Us -- S.Venkatesan Arihant Techno Solutions Pudukkottai www.arihants.com Mobile: +91 75984 92789

Secure and Efficient Data Communication Protocol for Wireless Body Area Networks
 
12:30
Secure and Efficient Data Communication Protocol for Wireless Body Area Networks Abstract: Wireless Body Area Networks (WBANs) are expected to play a major role in the field of patient-health monitoring in the near future, which gains tremendous attention amongst researchers in recent years. One of the challenges is to establish a secure communication architecture between sensors and users, whilst addressing the prevalent security and privacy concerns. In this paper, we propose a communication architecture for BANs, and design a scheme to secure the data communications between implanted/wearable sensors and the data sink/data consumers (doctors or nurse) by employing Ciphertext-Policy Attribute Based Encryption (CP_ABE) [1] and signature to store the data in ciphertext format at the data sink, hence ensuring data security. Our scheme achieves a role-based access control by employing an access control tree defined by the attributes of the data. We also design two protocols to securely retrieve the sensitive data from a BAN and instruct the sensors in a BAN. We analyze the proposed scheme, and argue that it provides message authenticity and collusion resistance, and is efficient and feasible. We also evaluate its performance in terms of energy consumption and communication/computation overhead.

Ciphertext-Policy Attribute based Encryption (CP-ABE) is a promising encryption technique that enables end-users to encrypt their data under the access policies defined over some attributes of data consumers and only allows data consumers whose attributes satisfy the access policies to decrypt the data. In CP-ABE, the access policy is attached to the ciphertext in plaintext form, which may also leak some private information about end-users. Existing methods only partially hide the attribute values in the access policies, while the attribute names are still unprotected. In this paper, we propose an efficient and fine-grained big data access control scheme with privacy-preserving policy. Specifically, we hide the whole attribute (rather than only its values) in the access policies. To assist data decryption, we also design a novel Attribute Bloom Filter to evaluate whether an attribute is in the access policy and locate the exact position in the access policy if it is in the access policy. Security analysis and performance evaluation show that our scheme can preserve the privacy from any LSSS access policy without employing much overhead.

SECURE COMMAND BROADCASTING BASED ON CP-ABE IN MILITARY ENVIRONMENT
 
02:57
Wireless media works on the principle of broadcast. The broadcast nature of wireless communication is very susceptible to malicious interception or unintentional interference. At least minimal security features are essential to prevent casual attacks. Mobile nodes in military environments such as a battlefield or a hostile region are likely to suffer from intermittent network connectivity and frequent partitions. Disruption-tolerant network (DTN) technologies are becoming successful solutions that allow wireless devices carried by soldiers to communicate with each other and access the confidential information or command reliably by exploiting external storage nodes. Some of the most challenging issues in this scenario are the enforcement of authorization policies and the policies update for secure data retrieval. Cipher text-policy attribute-based encryption (CP-ABE) is a promising cryptographic solution to the access control issues. However, the problem of applying CP-ABE in decentralized DTNs introduces several security and privacy challenges with regard to the attribute revocation, key escrow, and coordination of attributes issued from different authorities. In this paper, we propose how a command or data is broadcasted and encrypted using CP-ABE for decentralized DTNs where multiple key authorities manage their attributes independently.

Attribute-Based Security and Messaging
 
01:19:45
Attribute-Based Access Control (ABAC) provides a strategy for setting up access rules by exploiting attributes of principals and objects from an enterprise information system or digital credentials. ABAC can replace or complement other approaches like Access Control Lists (ACLs) and Role-Based Access Control (RBAC). In recent years, there has been a growth of other attribute-based systems including Attribute-Based Encryption (ABE) and Attribute-Based Messaging (ABM). In ABM email messages use addresses that describe recipient attributes rather than an explicit list of the recipients. Such addressing makes messages more efficient, exclusive, and intensional but raises challenges for security and privacy. This talk will discuss attribute-based security systems in general and use of ABAC and ABE to solve security problems faced by ABM. We describe requirements for ABM and a practical architecture that addresses them. We have built a prototype and collected performance results that show its feasibility for at least mid-size organizations. We end with some speculation on other ways to exploit attribute-based security techniques for goals like adding protection to databases and multi-tier web systems.

[WHIBOX 2016] Towards secure whitebox cryptography - Andrey Bogdanov
 
43:08
Whitebox cryptography aims to provide security for cryptographic algorithms in an untrusted environment where the adversary has full access to their implementation. This setting poses a fundamental challenge to security designers. Indeed, most whitebox solutions published to date have been practically broken. This talk will be three-fold. First, we will show new attacks on existing whitebox schemes which use techniques from symmetric-key cryptanalysis such as integral, differential and linear attacks. Second, we will give our novel approach to guaranteeing key extraction and decomposition security of whitebox encryption by essentially reducing it to the classical security of block ciphers such as AES in the standard black box setting. Next, we will present several families of whitebox schemes together with rigorous security analysis, detailed implementation study, and real-world applications.

Achieving data security and system efficiency in the data acquisition and transmission process are of great significance and challenging, because the power grid-related data is sensitive and in huge amount. In this paper, we present an efficient and secure data acquisition scheme based on CP-ABE (Ciphertext Policy Attribute Based Encryption). Data acquired from the terminals will be partitioned into blocks and encrypted with its corresponding access sub-tree in sequence, thereby the data encryption and data transmission can be processed in parallel. Furthermore, we protect the information about the access tree with threshold secret sharing method, which can preserve the data privacy and integrity from users with the unauthorized sets of attributes. The formal analysis demonstrates that the proposed scheme can fulfill the security requirements of the Cloud-supported IoT in smart grid. The numerical analysis and experimental results indicate that our scheme can effectively reduce the time cost compared with other popular approaches.

On the one hand, it frees data owners from the technical management, and is easier for data owners to share their data with intended users. On the other hand, it poses new challenges on privacy and security protection. To protect data confidentiality against the honest-but-curious cloud service provider, numerous works have been proposed to support finegrained data access control. However, till now, no schemes can support both fine-grained access control and time-sensitive data publishing. In this paper, by embedding timed-release encryption into CP-ABE (Ciphertext-Policy Attribute-based Encryption), we propose a new time and attribute factors combined access control on time-sensitive data for public cloud storage (named TAFC). Based on the proposed scheme, we further propose an efficient approach to design access policies faced with diverse access requirements for time-sensitive data.

This paper proposed some services for data security and access control when users outsource sensitive data for sharing on cloud servers. This paper addresses this challenging open issue by, on one hand, defining and enforcing access policies based on data attributes, and, on the other hand, allowing the data owner to delegate most of the computation tasks involved in fine grained data access control to untrusted cloud servers without disclosing the underlying data contents. Our proposed scheme enables the data owner to delegate tasks of data file re-encryption and user secret key update to cloud servers without disclosing data contents or user access privilege information. We achieve this goal by exploiting and uniquely combining techniques of attribute-based encryption (ABE), proxy re-encryption, and lazy re-encryption. Our proposed scheme also has salient properties of user access privilege confidentiality and user secret key accountability and achieves fine - graininess, scalability and data confidentiality for data access control in cloud computing. Extensive analysis shows that our proposed scheme is highly efficient and provably secures under existing security models.

Mobile: (0) 9952649690, Email: jpinfotechprojects@gmail.com, web: http://www.jpinfotech.org Attribute-based encryption (ABE) has been widely used in cloud computing where a data provider outsources his/her encrypted data to a cloud service provider, and can share the data with users possessing specific credentials (or attributes). However, the standard ABE system does not support secure deduplication, which is crucial for eliminating duplicate copies of identical data in order to save storage space and network bandwidth. In this paper, we present an attribute-based storage system with secure deduplication in a hybrid cloud setting, where a private cloud is responsible for duplicate detection and a public cloud manages the storage. Compared with the prior data deduplication systems, our system has two advantages. Firstly, it can be used to confidentially share data with users by specifying access policies rather than sharing decryption keys. Secondly, it achieves the standard notion of semantic security for data confidentiality while existing systems only achieve it by defining a weaker security notion. In addition, we put forth a methodology to modify a ciphertext over one access policy into ciphertexts of the same plaintext but under other access policies without revealing the underlying plaintext.

Protecting Your Right Attribute based Keyword Search with Finegrained Owner
 
12:35
Protecting your right: Attribute-based keyword search with fine-grained owner-enforced search authorization in the cloud Search over encrypted data is a critically important enabling technique in cloud computing, where encryption-before-outsourcing is a fundamental solution to protecting user data privacy in the untrusted cloud server environment. Many secure search schemes have been focusing on the single-contributor scenario, where the outsourced dataset or the secure searchable index of the dataset are encrypted and managed by a single owner, typically based on symmetric cryptography. In this paper, we focus on a different yet more challenging scenario where the outsourced dataset can be contributed from multiple owners and are searchable by multiple users, i.e. multi-user multi-contributor case. Inspired by attribute-based encryption (ABE), we present the first attribute-based keyword search scheme with efficient user revocation (ABKS-UR) that enables scalable fine-grained (i.e. file-level) search authorization. Our scheme allows multiple owners to encrypt and outsource their data to the cloud server independently. Users can generate their own search capabilities without relying on an always online trusted authority. Fine-grained search authorization is also implemented by the owner-enforced access policy on the index of each file. Further, by incorporating proxy re-encryption and lazy re-encryption techniques, we are able to delegate heavy system update workload during user revocation to the resourceful semi-trusted cloud server. We formalize the security definition and prove the proposed ABKS-UR scheme selectively secure against chosen-keyword attack. Finally, performance evaluation shows the efficiency of our scheme.

Decentralized Access Control With Anonymous Authentication Of Data Stored In Clouds
 
08:20
We propose a new decentralized access control scheme for secure data storage in clouds that supports anonymous authentication. In the proposed scheme, the cloud verifies the authenticity of the series without knowing the user’s identity before storing data. Our scheme also has the added feature of access control in which only valid users are able to decrypt the stored information. The scheme prevents replay attacks and supports creation, modification, and reading data stored in the cloud. We also address user revocation. Moreover, our authentication and access control scheme is decentralized and robust, unlike other access control schemes designed for clouds which are centralized. The communication, computation, and storage overheads are comparable to centralized approaches. Project Purpose Efficient search on encrypted data is also an important concern in clouds. The clouds should not know the query but should be able to return the records that satisfy the query. This is achieved by means of searchable encryption The keywords are sent to the cloud encrypted, and the cloud returns the result without knowing the actual keyword for the search. The problem here is that the data records should have keywords associated with them to enable the search. The correct records are returned only when searched with the exact keywords. Security and privacy protection in clouds are being explored by many researchers. addressed storage security using Reed-Solomon erasure-correcting codes. Authentication of users using public key cryptographic techniques has been studied Many homomorphic encryption techniques have been suggested to ensure that the cloud is not able to read the data while performing computations on them. Using homomorphic encryption, the cloud receives ciphertext of the data and performs computations on the ciphertext and returns the encoded value of the result. The user is able to decode the result, but the cloud does not know what data it has operated on. In such circumstances, it must be possible for the user to verify that the cloud returns correct results Project Scope Much of the data stored in clouds is highly sensitive, for medical records and social networks. Security and privacy are, thus, very important issues in cloud computing. In one hand, the user should authenticate itself before initiating any transaction, and on the other hand, it must be ensured that the cloud does not tamper with the data that is outsourced. User privacy is also required so that the cloud or other users do not know the identity of the user. The cloud can hold the user accountable for the data it outsources, and likewise, the cloud is itself accountable for the services it provides. The validity of the user who stores the data is also verified. Apart from the technical solutions to ensure security and privacy, there is also a need for law enforcement Access control is also gaining importance in online social networking where users store their personal information, pictures, videos and share them with selected groups of users or communities they belong to. Access control in online social networking has been studied Such data are being stored in clouds. It is very important that only the authorized users are given access to those information. A similar situation arises when data is stored in clouds, for example, in Dropbox, and shared with certain groups of people Decentralized Access Control With Anonymous Authentication Of Data Stored In Clouds.

Privacy Preserving Ciphertext Multi Sharing Control for Big Data Storage
 
05:14
Title: Privacy-Preserving Ciphertext Multi-Sharing Control for Big Data Storage Domain: Cloud Computing Key Features: 1. A privacy-preserving ciphertext multi-sharing mechanism is proposed to achieve the above properties. It combines the merits of proxy re-encryption with anonymous technique in which a ciphertext can be securely and conditionally shared multiple times without leaking both the knowledge of underlying message and the identity information of ciphertext senders/recipients. The new primitive is secure against chosen-ciphertext attacks in the standard model. 2. A great amount of electricity consumed data of each family located inside the district will be automatically transferred to the authority via Internet period by period. The need of big data storage, therefore, is more desirable than ever. A basic security requirement of big data storage is to guarantee the confidentiality of the data.

Ciphertext-Policy Attribute-Based Encryption (CP-ABE) has been adopted as a promising technique to provide flexible, fine-grained and secure data access control for cloud storage with honest-but-curious cloud servers. However, in the existing CP-ABE schemes, the single attribute authority must execute the time-consuming user legitimacy verification and secret key distribution, and hence it results in a single-point performance bottleneck when a CP-ABE scheme is adopted in a large-scale cloud storage system. Users may be stuck in the waiting queue for a long period to obtain their secret keys, thereby resulting in low-efficiency of the system. Although multiauthority access control schemes have been proposed, these schemes still cannot overcome the drawbacks of single-point bottleneck and low efficiency, due to the fact that each of the authorities still independently manages a disjoint attribute set. In this paper, we propose a novel heterogeneous framework to remove the problem of single-point performance bottleneck and provide a more efficient access control scheme with an auditing mechanism. Our framework employs multiple attribute authorities to share the load of user legitimacy verification. Meanwhile, in our scheme, a CA (Central Authority) is introduced to generate secret keys for legitimacy verified users. Unlike other multiauthority access control schemes, each of the authorities in our scheme manages the whole attribute set individually. To enhance security, we also propose an auditing mechanism to detect which AA (Attribute Authority) has incorrectly or maliciously performed the legitimacy verification procedure. Analysis shows that our system not only guarantees the security requirements but also makes great performance improvement on key generation.

Mobile: (0) 9952649690, Email: jpinfotechprojects@gmail.com, web: http://www.jpinfotech.org Data sharing in cloud storage is receiving substantial attention in Information Communications Technology, since it can provide users with efficient and effective storage services. To protect the confidentiality of the shared sensitive data, the cryptographic techniques are usually applied. However, the data protection is still posing significant challenges in cloud storage for data sharing. Among them, how to protect and revoke the cryptographic key is the fundamental challenge. To tackle this, we propose a new data protection mechanism for cloud storage, which holds the following properties. 1) The cryptographic key is protected by the two factors. Only if one of the two factors works, the secrecy of the cryptographic key is held. 2) The cryptographic key can be revoked efficiently by integrating the proxy re-encryption and key separation techniques. 3) The data is protected in a fine-grained way by adopting the attribute based encryption technique. Furthermore, the security analysis and performance evaluation show that our proposal is secure and efficient, respectively.
