中文摘要：

关键协议协议为安全通讯是必要的。在 thispaper，解决基于身份的密码学的固有的关键附带条件契约问题， escrow-freecertificate-based 证实了关键同意(CB-AK ) 有完美的 forwardsecrecy isproposed 的协议。我们的协议在椭圆形的曲线上使用配对。协议被描述， itsproperties 不过被讨论比较与聪明“ s 协议。

英文摘要：

Key agreement protocols are essential for secure communications. In this paper, to solve the inherent key escrow problem of identity-based cryptography, an escrow-free certificate-based authenticated key agreement （CB-AK） protocol with perfect forward secrecy is proposed. Our protocol makes use of pairings on elliptic curves. The protocol is described and its properties are discussed though comparison with Smart＇s protocol.
