可认证的无证书密钥协商协议

无证书公钥密码体制能有效地克服基于身份密码体制中密钥托管的限制，结合基于身份密码体制和可认证密钥协商的优点，提出了一个新的可认证无证书密钥协商协议。经过分析，该协议不仅满足一般密钥协商的安全特性，而且与已有的密钥协商相比，具有更少的对数运算。

Authenticated certificateless key agreement protocol

Certificateless public key cryptography was introduced to overcome the key escrow limitation of the identity-based cryptography. Combining the advantages of the identity-based cryptography and authenticated key agreement protocol, a new ID-based authenticated certificateless key agreement protocol that made use of bilinear pairings was proposed. The analysis shows that the protocol not only possesses the security properties that common key agreement protocols have, but also needs less pairing operation comp...
