Hybrid Trust Chain Security Model with Cloud Computing Based on Smart Grid

Abstract

The paper proposes a hybrid trust chain model with cloud computing based on smart grid, for the purpose of enhancing the ability of smart grid cloud computing system to deal with most malicious attacks and reduce the security risk. The model merges the trust transfer model and the separation model, based on a set of trust chain establishment scheme defined by Trusted Computing Group (TCG), and improves the traditional chain and star trust model, in order to boot and establish a trusted secure computing environment. Proved by examples, the hybrid trust chain security model puts the security of cloud computing on the trusted computing platform, which has significant effects on improving the credibility of the computer system, increasing the security of the cloud foundation and ensuring the integrity of the information.
