Data service is a specialization of Web service, and end-users can synthesize cross-organizational data by composing data services. As composite schemes overlap each other, some primitive data services could be called repeatedly by composite data services, so that the response delay and server load are aggravated. In this paper, an optimized strategy for data service response with template-based caching and compression is proposed. Firstly, the strategy uses the message template to extract the application-relevant values from SOAP messages. Secondly, the strategy holds the objects from application-relevant values rather than XML representations to decrease the overhead of SOAP message parsing. Thirdly, the strategy uses the XMill compression algorithm to decrease the volume of data transmitted. Extensive experiments based on Spring-WS-Test benchmark demonstrate the strategy is an effective approach to reduce response latency and server load compared to non-caching tehcnniques. © Springer International Publishing Switzerland 2014.

In this paper, a novel proxy re-encryption (PRE) scheme with keyword search is proposed, where only the ciphertext containing the keyword set by the delegator can be transformed by the semi-trusted proxy and then decrypted by delegatee. In the proposed scheme, the semi-trusted proxy can convert the ciphertext encrypted under the delegator’s public key into the ciphertext encrypted under the delegatee’s public key. In addition, only the delegatee’s email gateway with a trapdoor can test whether or not a given cipheretext containing some keyword, but can learn nothing else about the sensitive data of email. We proposed an identity-based proxy re-encryption with keyword search scheme, where the delegator and the delegatee extract keys from a trusted party called the key generator center (KGC), who generates public-private key pair for delegator and delegatee based on their identities. Meanwhile, the identity-based proxy re-encryption with keyword search scheme satisfies the properties of PRE including unidirectionality, multi-use and transparency. Additionally, the proposed scheme is efficient in terms of both computation and communication, and can realize security privacy preserving in cloud computing environments. © 2014 Trans Tech Publications, Switzerland.

Forward-secure signatures are proposed to deal with the key exposure problem. Compared to regular signatures, forward-secure signatures have a special update algorithm that can evolve the new private key in each time period. Therefore, it can protect the security of signatures previous to the time period of key exposure. The efficiency is an important issue of forward-secure signatures. In this paper, we construct a new forward-secure signature scheme using bilinear maps. In this scheme, all performance parameters have complexities of log magnitude in terms of the total time periods. In addition, our scheme needs very few (only triple) pairing operations in the verifying algorithm, which is very important because the pairing operation is very time-consuming. This scheme is proved to be forward secure in the random oracle model assuming the CDH problem is hard. Finally, we give some applications of this scheme including constructing an intrusion-resilient signature scheme and constructing a forward-secure threshold signature scheme. © 2014 Elsevier Inc.

Certificateless signature eliminates the need of certificates in traditional public key signature and solves the inherent key escrow problem in identity-based signature. Therefore, it is an important secure requirement to solve key escrow problem in certificateless signature scheme, i.e., certificateless signature scheme should to resist the malicious but passive KGC attack. Key-insulated signature reduces the endangerment of private key leakage. Recently, Chen et al. propose a certificateless key-insulated signature scheme, and give the security proof in the standard model. In this paper, we give a security analysis of Chen et al.'s scheme. Our analysis reveals that Chen et al.'s scheme is vulnerable to the malicious-but-passive KGC attack.

A Provably secure Certificate based ring signature without pairing

International Journal of network security 2014年第4期16卷 278-285页

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 this paper, an identity-based conditional proxy re-encryption (PRE) scheme is proposed, where a delegator provides a re-encryption key satisfying one condition to a semi-trusted proxy who can convert a ciphertext encrypted under the delegator's public key into one that can be decrypted using the delegatee's private key. We address the identity-based proxy re-encryption scheme, where the delegator and the delegatee request keys from a trusted party known as a key generator center (KGC), who generates private keys for delegator and delegatee based on their identities. Meanwhile, the identity-based conditional proxy re-encryption scheme satisfies the properties of PRE including unidirectionality, non-interactivity and multi-hop. Additionally, the identity-based conditional proxy re-encryption scheme is efficient in terms of both the communication cost and the computing cost, and can realize security secret sharing in cloud computing environments. © (2014) Trans Tech Publications, Switzerland.

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.

With the fast development of mobile devices, the volume of mobile internet traffic increased dramatically. Various information is potential to be mined from it. In this paper, the large-scale mobile internet traffic is employed to protect end-users from mobile malwares that emerge at a similar speed to that of mobile internet. Traditional mobile malware detection methods often inevitably consume the limited battery life and computing resource of the end device. To solve these problems, a novel framework, Mining Mobile Internet Packets for Malware Detection (MMIP-MD), is proposed. Since the new technology of format preserving encryption (FPE) made the data of mobile internet traffic from telecommunication operators accessible and minable without leaking end-users' privacies, the framework thus aims feasibly at detecting mobile malwares using the traffic data only, which moves the detection from the end device to the internet side. It has good extensibility since a variety of mining algorithms can be applied on this framework to discover behavioral patterns of malwares. In addition, a real example of Bayes classification was implemented to illustrate the framework and test its feasibility.
