利用垂直阵列构作了一类Cartesian认证码,计算了它们的参数,并且在编码规则按等概率分布选取时,成功的模仿攻击和成功的替换攻击概率也被算出。 A Cartesian authentication code is constructed by using a vertical array, their parameters are calculated, and the probability of successful mock attacks and successful replacement attacks are also calculated when the coding rules are selected according to an equal probability distribution.
