摘　　要：该文利用有限域上的酉几何构作了三类新的带仲裁的认证码,计算了码的参数;当编码规则按等概率分布选取时,计算出各种攻击成功的概率。研究结果表明可用酉几何进一步构作多类带仲裁的认证码。Three families of authentication codes with arbitration are constructed from unitary geometry, the parameters of the codes are computed. Assuming the encoding rules of the transmitter and the decoding rules of the receiver are chosen according to a uniform probability distribution, the probabilities of each kind of deceptions are also computed.
