The Cloud Access Control Based on Dynamic Feedback and Merkle Hash Tree

For cloud environment is an open, dynamic environment, analysed the lack of based on the Merkle hash tree architecture, we propose a high efficiency, flexible and dynamic feedback, remote authentication mechanisms. This paper describes TPM_ Trust command enhanced the functionality of the existing TPM (trusted platform module), and analyze the discussion of the advantages of the new mechanism, and proposes a measuring method based on subjective trust.
