摘　　要：在奇特征的正交几何空间中构作一个Cartesian认证码，并且计算出认证码的参数，成功的模仿了攻击概率和替换攻击概率．One Cartesian authentication code from odd characteristic orthogonal geometry over a finite field with the characteristic not being 2 was constructed. Its size parameters were calculated and its probilitles of impersonation attack and substitution attack were successfully simulated.

关 键 词：认证码 奇特征 正交几何 有限域 攻击概率 编码
