基于EPR协议和Rabin密码的签名方案

提出利用具有可证明无条件安全性的量子密钥分配协议EPR，同具有可证明的数学上大数分解难题与破解其密码体制相等价的Rabin密码相结合的一种数字签名方案。该签名方案采用Rabin公钥密码体制实现数字签名，并以对称量子密钥作为临时会话密钥。经安全性分析，此签名方案可有效抵御各种主动攻击和被动攻击，可用于点对点的保密通信，且同时具有认证的效果。

Signature scheme based on EPR Protocol and Rabin Cipher

By means of quantum secret-key distribution protocol EPR with proved unconditional security, and the Rabin Cipher, which has a equal difficulty between breaching itself and the problem of analyzing a big number, a digital signature scheme is proposed. Its signature carried out by Rabin Public Cipher System, and the session-key consists of symmetrical quantum key. Analyzed by safety, it can effectively defense the assault of initiative or passiveness, and can be used in p2p confidential communication, as well as authentication.
