A novel hierarchical access control scheme for perceptual layer of the IoT is presented based on resources hierarchies, which could conform to the secure and efficient access requirement of multi-user. In the scheme, every hierarchical node is composed of perceptual nodes which provide resources with the same levels of security. More hierarchical nodes can be modeled as a set of partially ordered classes. With this mode, a deterministic key derivation algorithm is designed, which makes every user and perceptual node possesses a single key material to get some keys, and obtains the resources at the presented class and all descendant classes in the hierarchy. Furthermore, a mechanism of Merkle tree is introduced to guarantee secure and efficient multi-user key material derivation by independent of each hash link. Compared with previous proposals, the scheme is more suitable for multi-user to access resources of perceptual layer in IoT.

The paper is mainly used to provide the equivalence of two algorithms of independent component analysis (ICA) based on the information bottleneck (IB). In the viewpoint of information theory, we attempt to explain the two classical algorithms of ICA by information bottleneck. Furthermore, via the numerical experiments with the synthetic data, sonic data, and image, ICA is proved to be an edificatory way to solve BSS successfully relying on the information theory. Finally, two realistic numerical experiments are conducted via FastICA in order to illustrate the efficiency and practicality of the algorithm as well as the drawbacks in the process of the recovery images the mixing images. © 2015 Qiao Ke et al.

In Eurocrypt 2003, Gentry introduced the notion of certificate-based encryption. The merit of certificate-based encryption lies in implicit certificate and no private key escrow. This feature is desirable especially for the efficiency and the real spontaneity of ring signature, which involve a large number of public keys in each execution. In this paper, we propose an efficient certificate-based ring signature scheme which does not require any pairing computation. Furthermore, this scheme is proven secure under the Discrete Logarithm assumption in the random oracle model. To the best of authors' knowledge, this is the first construction of certificate-based ring signature scheme in the literature that has such kind of feature.

In order to reduce the complexity of traditional multithreaded parallel programming, this paper explores a new task-based parallel programming using the Microsoft .NET Task Parallel Library (TPL). Firstly, this paper proposes a custom data partitioning optimization method to achieve an efficient data parallelism, and applies it to the matrix multiplication. The result of the application supports the custom data partitioning optimization method. Then we develop a task parallel application: Image Blender, and this application explains the efficiency and pitfall aspects associated with task parallelism. Finally, the paper analyzes the performance of our applications. Experiments results show that TPL can dramatically alleviate programmer burden and boost the performance of programs with its task-based parallel programming mechanism.

Aiming at the problem of intelligent path guidance in the parking lot, an improved Particle Swarm Optimization Algorithm(PSO) is proposed in this paper to find the optimal path. In order to overcome the shortcomings that standard PSO traps into local optima easily and improve the convergence speed of algorithm, the concept of GA and Multi-thread technology are introduced. The experiment results show that the proposed parallel hybrid PSO algorithm(PHPSO) is relatively steady with faster convergent rate. Especially for multi-nodes, the efficiency is improved obviously. So the proposed PHPSO is well suited for large parking lot.

Attribute-based encryption based access control scheme with constant-size ciphertext in cloud computing

引用

Jilin Daxue Xuebao (Gongxueban)/Journal of Jilin University (Engineering and technology Edition) 2014年第3期44卷 788-794页

Based on Attribute-Based Encryption (ABE), a variety of access control schemes have been constructed in cloud computing. However, in these schemes, the ciphertext overhead goes linearly with the number of attributes used in encryption. To address this concern, a CCP-ABE (Constant-size Ciphertext Policy ABE) based access control scheme is proposed. The original data is encrypted by a symmetric key;then symmetric key is encrypted under an AND-gate access policy. Only the user who possesses a set of attributes that satisfy the policy can recover the symmetric key. The security of the proposed scheme is proved based on security of the CPA (Chosen Plaintext Attack) secure CCP-ABE scheme. Moreover, a method of constructing CCA (Chosen Ciphertext attack) secure CCP-ABE schemes is introduced. Performance analysis indicates that the ciphertext overhead over the number of attributes included in ciphertext is constant-size rather than linearity.

User interaction is one of the most important features of online social networks, and is the basis of research of user behavior analysis, information spreading model, etc. However, existing approaches focus on the interactions between adjacent nodes, which do not fully take the interactions and relationship between local region users into consideration as well as the details of interaction process. In this paper, we find that there exists influence transfer effect in the process of user interactions, and present a regional user interaction model to analyze and understand interactions between users in a local region by influence transfer effect. Based on real data from Sina Weibo, we validate the effectiveness of our model by the experiments of user type classification, influential user identification and zombie user identification in online social networks. The experimental results show that our model present better performance than the PageRank based method and machine learning method.

A secure self-destruction scheme with IBE for the internet content privacy

Jisuanji Xuebao/Chinese Journal of computers 2014年第1期37卷 139-150页

With the rapid emerging of novelty Web services and cloud services, privacy information and documents of users become increasingly easy to be exposed in the Internet. To tackle the issue of lifecycle security of the privacy information and documents in the Internet, in this paper, we propose the idea of combining the three security methods of multilevel security, identity-based encryption (IBE), and distributed hash table (DHT) network. And we further propose an IBE-based secure self-destruction (ISS) scheme to protect the confidentiality and privacy of the Internet content by self-destruction after a predefined time. In our proposed ISS security scheme, the Internet content is first partitioned into many segments with diverse security levels, and each segment is encrypted with a symmetric key to obtain primitive ciphertext. By applying the methods of association and extraction, the primitive ciphertext is turned to associated ciphertext, which is then divided into extracted ciphertext and encapsulated ciphertext. The latter is encapsulated into the Internet content self-destructing object (CDO), which is stored into the storage services provider. Furthermore, to protect the privacy security when the CDO expired, the symmetric key is encrypted using the IBE algorithm based on the identity of the authorized user. The combination of this key's ciphertext and the extracted ciphertext, by means of Lagrange polynomial processing, generates mixture ciphertext shares. Then those shares are distributed into nodes within the DHT network and will be automatically discarded over the deadline when the primitive ciphertext and the symmtric key are unrecoverable. Consequently, the ISS scheme achieves the aim of secure self-destruction. Comprehensive analysis shows that the ISS scheme is able to satisfy all the design demands and is more secure than existing schemes. The ISS scheme can resist against not only the traditional cryptanalysis and brute-force attack, but also the Sybil
