摘要
利用有限域上辛几何、酉几何与正交几何构造了一类笛卡尔认证码，并且计算了其参数．假设编码规则是按照一种均匀概率分布选择的，那么假冒攻击成功的概率ＰＩ和替换攻击成功的概率ＰＳ也被计算。
A construction of Cartesian authentication codes,which is a generalization of some results in [4,5],is presented. Assuming that the encoding rules are chosen according to a uniform probability distribution,the probabilities PI and PS of a successful impersonation attack and a successful substitution respectiverly,of these codes are also computed.
