无可信中心的Ad Hoc网络身份认证方案

Identity authentication scheme for Ad Hoc network without trusted party

利用门限机制,提出了一种基于椭圆曲线密码的Ad Hoc网络身份认证方案。该方案采用椭圆曲线数字签名来生成可验证的证书,无需可信中心,能够有效地抵御网内和网外的攻击者。分析表明,方案的安全性是基于椭圆曲线离散对数问题的难解性,其执行效率较高。

Through threshold mechanism,an identity authentication scheme for Ad Hoc network is proposed based on elliptic curve cryptography.In this scheme,the author can generate verifiable certificate by using elliptic curve digital signature without a trusted party,and the scheme can resist interior and exterior attackers effectively.Analyse show that the security of this scheme is based on the difficulty of solving the elliptic curve cryptography discrete logarithm problem,and its implementation is efficient.
