In this paper, we propose a certificateless noninteractive key exchange protocol. No message exchange is required in the protocol, and this feature will facilitate the applications where the communication overhead matters, for example, the communications between the satellites and the earth. The public key certificate is removed as well as the key escrow problem using the certificateless public key cryptosystem. The security of the protocol rests on the bilinear Diffie–Hellman problem, and it could be proved in the random oracle model. Compared with previous protocols, the new protocol reduces the running time by at least 33.0%.

具有可证明安全性的无证书非交互式密钥交换协议

在本文中，我们提出了一种无证书的非交互式密钥交换协议。协议中不需要消息交换，并且此功能将促进那些通信开销很重要的应用程序，例如卫星与地球之间的通信。使用无证书的公共密钥密码系统可以删除公共密钥证书以及密钥托管问题。协议的安全性取决于双线性Diffie-Hellman问题，可以在随机预言模型中证明。与以前的协议相比，新协议将运行时间减少了至少33.0％。
