摘　　要：具有仲裁的认证码既要防止敌手的欺骗，又要防止收方和发方的互相欺骗．本文给出一种由酉几何构造等概的具有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．Authentication codes with arbitration protect against deceptions from the transmitter and from the receiver as well as those from the opponent. In this paper, we describe a new construction of equally authentication codes with arbitration using unitary spaces parameters and the probability of susccessful attacks are computed.
