数字签名的一个公平交换协议

摘要

A fair exchange protocol by means of G. Ateniese's verifiable encryption of digital signatures is introduced. Two parties exchanged digital signatures fairly over Internet using the protocol. In the protocol, one part encrypted the valid signature on message, and then proved to the others that the encryption contained the signature. Its security is based on the discrete logarithm problem.%给出了一个应用G.Ateniese的可验证加密的公平交换协议,即构成了在因特网上公平交换数字签名的双方之间的一个协议.通过该协议,一方对消息的有效签名进行加密,并随后向另一方证明他得到的密文确实包含该签名,其安全性基于离散对数问题.
