基于伪辛几何空间的带仲裁的认证码构造

摘要

Unconditionally secure authentication codes with arbitration protects against deception from the transmitter and from the receiver as well as those from the opponent. A new construction of authentication codes with arbitration using pseudo -symplectic spaces is described. Some parameters and the probabilities of successful attacks are computed.%带仲裁的认证码既要防止敌手的欺骗,又要防上收方和发方的互相欺骗.给出一种由伪辛几何空间构造带仲裁的认证码的方法,并计算了有关参数,分析了各种攻击成功的概率.
