摘　　要：利用酉几何构作了一个non-Cartesion认证码,计算了它的参数;当编码规则按等概率分布选取时,求出了模仿攻击和替换攻击成功的概率.Using subspaces of Unitary geometry, we construct a class of non -Cartesion authentication code, and compute its size parameters. Moreover assuming that the encoding rule is chosen according to a uniform probability distribution, we also compute the probabilities of a successful impersonation attack and of a successful substitution attack respectively.
