摘要
双重签名是安全电子交易协议的一个重要技术,它将摘要和数字签名结合起来,使得交易中的各方仅得到部分消息即可完成验证从而达成多方协议。论文利用Petri网对双重签名进行建模和形式化描述,并就安全性对此模型进行了分析。
Dual signature is an important feature of Secure Electronic Transaction protocol. Its combination of hashes and digital signatures makes several parties agree on a transaction without each of them receiving a complete view of transaction. In this paper, dual signature is modeled and formally specified on the basis of Petri nets, and then its security is discussed and analyzed.
