【摘要】 针对有限域上计算离散对数的困难,提出了一种新的身份认证与密钥协商安全协议——PJY。PJY安全协议通过两次握手就可以验证通信双方的身份,同时产生对等的会话密钥。采用串空间模型分析该安全协议的正确性,通过构造渗透串空间模型,采用认证测试证明了PJY安全协议在任意一种攻击串模式下都具有单射一致性和机密性,从而证明了PJY安全协议的正确性。更多还原

【Abstract】 We proposed a novel PJY identity authentication and key agreement security protocol based on computational difficulty of discrete logarithm in finite field.The PJY security protocol can validate identity of the both parties with two session,and generate peer session key.We analyzed the correctness of the security protocol on strand space model.First we constructed infiltrate strand space,and proved the PJY security protocol has injective agreement and secrecy by authentication tests under arbitrary penetration strand,so proved the PJY security protocol is correct.更多还原
