摘要：In this paper, formal verification methodologies and the SPR (Safety Problem Resolver) model checking tool are used for verifying a security model's safety. The SPR tool makes it possible to analyze security issues on security systems based on the access control model. To illustrate this approach, a case study of the Simple Access Control Model (SACM) is used and specific safety problems of the security model are analyzed using the SPR tool.
