摘要:
Based on the in-depth progress on research of the security and trust in a single information system, and the increasing requirements in interconnection between different information systems, this paper proposes a trusted interconnection model. Through establishes identity mapping and collision detection mechanism in system boundary, it can complete the identity conversion when cross-system access occurs. After the conversion, access decision is still based on the system's own security policy. So, this model can make the interconnection between different systems, at the same time, it can ensure the security of the original system will not be destroyed. In addition, this paper gives a formal proof of this trusted interconnection model, and demonstrates its safety.
