摘要
利用伪辛几何构作了一类带仲裁的认证码,计算了码的参数.当发方与收方的编码规则都等概率分布选取时,计算出各种攻击成功的概率,并在特殊情况下得到了一组完备码.
A construction of authentication codes with arbitration from pseudo-sympletic geometry is given and the parameters of the codes are computed. Assuming the rule of the transmitter and the receiver are chosen according to a uniform probabilities distribution and the probabilities of success for different type of deceptions are also computed. In a special case, a perfect code is obtained.
