An Improved Formal Model of Cryptographic Protocol
一种改进的密码协议形式化模型

MSR (multiset rewriting) model is a technique of protocol modeling based on multiset rewriting. According to the results of the current study, this model is not perfect. Since the intruder model of MSR model is not suitable for the verification of the protocol, it was improved. Using this model, the secrecy and authentication of the cryptographic protocols are described. The practice proves the improvement of the former model.
