不使用双线性对的无证书认证协议

Certificateless Authentication Protocol Without Pairing

  • 摘要: 基于离散对数问题,提出了一种不使用双线性对的无证书签密方案。利用该签密方案,提出了一种高效的、不使用双线性对的无证书认证协议,并在CK模型下提供安全性证明。分析表明,该协议具有双向实体认证、完美的向前保密性等安全属性,满足了认证的安全需求。此外,该认证协议仅需进行1次对称加密、3次指数运算和1轮通信即可完成,通信开销小,计算量较低。

     

    Abstract: A new certificateless signcryption scheme without using the bilinear pairings was presented based Discrete-Logarithm firstly,which was proved security in the random oracle model.Secondly,with the proposes signcryption scheme Canetti-Krawczyk model,the author proposes an efficient certificateless authentication and key exchange protocol without pairings.The security analysis of the proposed protocol in the implementation plan with the Canetti-Krawczyk model is presented in this paper.The results show that the proposed protocol is session-key secure with perfect forward secrecy.Moreover,the implementation of the protocol is just 1 encryption operation,3 exponent operations and twice communications.
