摘　　要：利用有限域上奇特征的正交几何构作了一个Ｃａｒｔｅｓｉａｎ认证码，并且计算了其参数．假设编码规则是按均匀概率分布选取的，则模仿攻击成功的概率ＰＩ和替换攻击成功的概率ＰＳ也被计算．One construction of cartesian authentication codes from orthogonal geometry over finite fields with characteristic not 2 is given in this paper. Its size parameters are computed. Assuming that the encoding rules are chosen according to a uniform probability distribution,then the probabilities of successful impersonation attack and of successful substitution attack are also computed.
