摘　　要：利用有限域上奇特征的正交几何构作了一个新的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，则摸仿攻击成功的概率ＰＩ和替换攻击成功的概率ＰＳ也被计算。A new construction of Cartesian authentication codes from orthogonal geometry over finite fields with characteristic ≠2 is given in this paper. Its size parameters are computed. Assume that the encoding rules are chosen according to a uniform probability distribution, then the probabilities of successful impersonation attack and of succssful substitution attack are also computed.

关 键 词：正交几何 有限域 C认证码 编码规则
