Abstract

无证书的公钥密码学被介绍克服基于身份的密码学的 keyescrow 限制。它联合基于 theidentity 的密码学和传统的 PKI 的优点。许多无证书的公钥加密 andsignature 计划被建议了。然而，在 CL-PKE 的关键协议很少被讨论。Inthis 纸，我们在场一新无证书二聚会认证钥匙协议协议 andprove 它的安全属性。与存在协议相比，我们的协议是更有效的。

Two-party authenticated key agreement in certificateless public key cryptography

Yijuan Shi, Jianhua Li

Certificateless public key cryptography was introduced to overcome the key escrow limitation of the identity-based cryptography. It combines the advantages of the identity-based cryptography and the traditional PKI. Many certificateless public key encryption and signature schemes have been proposed. However, the key agreement in CL-PKE is seldom discussed. In this paper, we present a new certificateless two party authentication key agreement protocol and prove its security attributes. Compared with the existing protocol, our protocol is more efficient.
