Current remote attestation schemes in trusted cloud computing lack of dynamic measure scheme of virtual computing nodes. In this paper, by the analysis and comparison of existing remote attestation technology, we propose a trust measure of virtual computing node running state, and a remote attestation scheme based on the trust measure results and CP-ABE attribute access control. By RO security analysis, and a simulation, we verify the security and efficiency of the program. The trust measure of platform running state is mainly based on the trust rating of the programs running on the platform, and a total trust value of the platform by an algorithm. The trust measure of virtual computing node running state is mainly based on the trust measure of the programs running on the platform and CP-ABE attribute access control. The remote attestation for the trust measure of platform running state is based on CDH problem. In this paper, we carry out simulation experiment with different proportions of non-credible nodes and the experiment results verify the trust evaluation efficiency of the scheme on the virtual machine.

Trust Measure

Remote attestation is the key technology of trusted computing. The existing remote attestation techniques lack of the trust measure of platform running state. In this paper, by the analysis and comparison of existing remote attestation technology, we propose a trust measure of platform running state, and a remote attestation program based on the trust measure results. By RO security analysis, and a simulation, we verify the security and efficiency of the program. The trust measure of platform running state is mainly based on the trust rating of the programs running on the platform, and a total trust value of the platform by an algorithm. The remote attestation for the trust measure of platform running state is based on K-CCA problem. In this paper, we carry out simulation experiment with different proportions of non-credible nodes and the experiment results verify the trust evaluation efficiency of the scheme on the platform.

Configuration Information

In the cloud computing mode TCCP, there exist shortcomings of overburdened trusted TC, the anonymity of nodes and configuration information of platform can’t be guaranteed. In this paper, we propose an anonymous scheme based on attribute certificate. The scheme is achieved by the trusted ring signature based on attribute certificate. By the security analysis, the anonymity and platform configuration information of computing nodes is guaranteed. By simulation experiment, we obtain the efficiency of the scheme. Comparing with Boneh ring signature based on ECC algorithm, this scheme has a great superiority in terms of large amount of ring signatures.

Catastrophic Damage

As the utilization of sensor networks continue to increase, the importance of security becomes more profound. Many industries depend on sensor networks for critical tasks, and a malicious entity can potentially cause catastrophic damage. We propose a new key exchange trust evaluation for peer-to-peer sensor networks, where part of the network has unconditionally secure key exchange. For a given sensor, the higher the portion of channels with unconditionally secure key exchange the higher the trust value. We give a brief introduction to unconditionally secured key exchange concepts and mention current trust measures in sensor networks. We demonstrate the new key exchange trust measure on a hypothetical sensor network using both wired and wireless communication channels.

Cloud Computing Services

In order to solve the trust problems between users and cloud computing service providers in cloud computing services, the existing trust evaluation technology and access control technology in the cloud computing service are analyzed. And the evaluation index of cloud computing is also analyzed. Users can calculate the relevant indicators of cloud computing service according to their own business goals, and choose the appropriate cloud computing services according to their own trust need. In addition, the reliability assessment method of users based on the service process is proposed. Cloud computing access control system can be used for user credibility evaluation, and it can handle user access requests according to user's creditability. In the study, a cloud computing service trust evaluation tool is designed, and the modeling and architecture designs of trust evaluation are also given. The effectiveness of the method is verified by experiments on cloud computing service evaluation methods.

And Storage

Data deduplication serves as an effective way to optimize the storage occupation and the bandwidth consumption over clouds. As for the security of deduplication mechanism, users’ privacy and accessibility are of utmost concern since data are outsourced. However, the functionality of redundancy removal and the indistinguishability of deduplication labels are naturally incompatible, which bring about a lot of threats on data security. Besides, the access control of sharing copies may lead to infringement on users’ attributes and cumbersome query overheads. To balance the usability with the confidentiality of deduplication labels and securely realize an elaborate access structure, a novel data deduplication scheme is proposed in this paper. Briefly speaking, we drew support from learning with errors (LWE) to make sure that the deduplication labels are only differentiable during the duplication check process. Instead of authority matching, the proof of ownership (PoW) is then implemented under the paradigm of inner production. Since the deduplication label is light-weighted and the inner production is easy to carry out, our scheme is more efficient in terms of computation and storage. Security analysis also indicated that the deduplication labels are distinguishable only for duplication check, and the probability of falsifying a valid ownership is negligible.

Novel Model

This paper, present a novel model to resolve the problems of evaluating trust value of nodes, and prepare a dynamic supervising in ad hoc network as well. Trust evaluation is not only based on direct interactions among nodes, but also observing previous behaviors of nodes, which come from all interactions through the network. This model specially decreases the delay time of selecting a new head for each cluster, which leads to prepare a dynamic monitoring in intra cluster and inter cluster in ad hoc network.
