如今，诸如在线聊天（例如，MSN）和SMS（短消息服务）的客户端到客户端应用正变得越来越流行。这些客户端到客户端的应用程序正在彻底改变我们的通信方式。密码认证密钥交换（PAKE）协议是一种三方协议，它为通信双方提供了一种在公共服务器的帮助下建立安全信道的方法。在本文中，我们提出了一个有效的三方PAKE协议的客户端到客户端的应用程序，它具有更好的性能比现有的一般结构。我们还表明，该协议是安全的，在一个正式的安全模型。
Nowadays, client-to-client applications such as online chat (e.g. MSN) and SMS (Short Message Services) are becoming increasingly prevalent. These client-to-client applications are revolutionizing the way we communicate. Three-party PAKE (password authenticated key exchange) protocols provide a means for the two communicating parties holding passwords to establishment a secure channel between them with the help of a common server. In this paper, we propose an efficient three-party PAKE protocol for the client-to-client applications, which has much better performance than the existing generic constructions. We also show that the proposed protocol is secure in a formal security model.
