一种基于复合问题的三方密钥交换协议

摘要

为了保证网络环境的安全通信，三方密钥交换协议得到广泛关注。结合对称加密算法、异或运算，将口令与身份进行简单复合，提出了一种三方密钥交换协议。该协议具有前向安全性，并能抵抗在线字典攻击、假冒攻击等。%In order to guarantee the security of the network environment communication, the three key exchange protocol is widely concerned. In this paper in combination with the symmetric encryption algorithm, exclusive or operation, and password and identity have been compounded, A three-party key exchange protocol is proposed. The protocol is with forward security, and resistance to online dictionary attack, fake attack, etc.
