At the beginning, the paper analyzes the basic principle and structure of PON. The set of integrated automation network platform according to the information transmission characteristics of mine based on access network and Ethernet of PON is designed. The paper descripes the platform in detail from aspacts of designs of system hardware, software and others. The results show that the system platform can improve the efficiency and reduce the cost.展开更多

This paper proposes a trustworthy integrity measurement architecture, BBACIMA, through enforcing behavior-based access control for trusted platform module (TPM). BBACIMA introduces a TPM reference monitor (TPMRM) to ensure the trustworthiness of integrity measurement. TPMRM enforces behavior-based access control for the TPM and is isolated from other entities which may be malicious. TPMRM is the only entity manipulating TPM directly and all PCR (platform configuration register) operation requests must pass through the security check of it so that only trusted processes can do measurement and produce the proof of system states. Through these mechanisms malicious user can not enforce attack which is feasible in current measurement architectures.展开更多
