Dynamic Remote Attestation on Trusted Computing

Abstract:

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.
