带身份认证的BB84协议

The BB84 Protocol with identity authentication

利用量子特性实现量子保密通信是目前量子信息学界和密码学界关注的热点问题之一。提出带身份认证的BB84协议,在密钥产生和分配过程中,通信双方利用初始密钥进行身份认证,既能提高效率,又增强了系统的安全性。

Now it is a hot topic to use the character of quantum for quantum encrypt communication in password and quantum information world.So the BB84 protocol with identity authentication is proposed.In production and disposition of the BB84 protocol with identity authentication,users can authenticate identity each other by the authentication key,which can not only strengthen its security,but also improve efficiency.
