摘要
本文分析了基于密钥分配中心(KDC)的密钥分配技术,为了防止会话密钥被篡改或泄露、消息的重放攻击,采用在认证过程中增设公开密钥和附加消息认证码的机制,并采用混沌加密算法产生伪随机序列,实现了认证和加密过程中的“一次一密”。该研究结果有助于序列密码算法在信息安全及网络加密卡中的应用。
This paper analyses key distributed technology based on key distribution center and provides a mechanism of opening the key and the authentication code of attached messages in authentication process to prevent session key from revealing, revising and distorting, and prevent the replay message from attacking. Use chaos encryption algorithm to produce a pseudo-random sequence in order to realize one-time-pad in authentication and encryption process. The results of this research can be applied to information safety and encrypted network card.
