摘要：Take-Grant protection model (TGPM) is a powerful method for modeling access rights in a wide range of systems. It is graph based formal method that is used for studying situations that rights can unintentionally be transferred as rights leakage. Deduction of new rights using rules of this model is difficult task especially for systems that have numeras parties and many rights between them. In this paper a novel model of TGPM using colored Petri net is presented. Using model checking of state space of the model, is proved that a specific party in the system can have specific right over other party or not in a case study? If a right leakage exists, then using model checking of the state space of the model an automatic proof can be generated.
