摘    要:密钥协商协议允许两个或多个用户在公开网络中建立一个共享密钥,是最基本的密码原型和公钥密码学的基础.本文综述密钥协商协议的研究进展,包括密钥协商的安全模型、传统离散对数环境下的密钥协商协议、最近发展起来的基于双线性对的密钥协商协议以及基于口令的密钥协商协议,指出了密钥协商协议中的公开问题和未来可能的发展方向.

关 键 词:密钥协商  密钥分发  群密钥协商  认证密钥协商  公钥密码体制

Abstract:Key agreement protocols allow two or more users to establish a common secret key though open networks.This notion of key agreements is one of the most fundamental cryptographic primitives and the base of public cryptography.This paper presents a survey on the state of key agreements including the security model of key agreements,the key agreement protocols in the context of conventional discrete logarithms,pairing-based key agreement protocols and password-based key agreement protocols.We also remark some o...
Keywords:Key agreement  Key distribution  Group key agreement (GKA)  Authenticated key agreement  Public key cryptosystem
