针对现有安全策略模型BLP与BIBA结合应用存在可用性差的问题,通过引入可信度量机制提出了基于可信计算的多级安全策略TCBMLSP(Trust Computing Based Multilevel Security Policy),该策略能够保证主客体的行为可信,解决多级信息的安全流通,并通过可信计算的远程证明机制使得该策略能够应用于不同安全域之间的可信通信,较好的解决了可用性差的问题。
【英文摘要】
Aiming at the problem of the security policy existing which Combinate BLP and BIBA, In this paper, Trust computing based multilevel security policy has been introduced. Through the concept of trusted measurement, the subject and object's action can proved to be trust. It can solve the multilevel security information transition and can transition the information between two domain using the remote attestation.
