摘　　要：利用有限域上的伪辛几何构作一类Cartesian认证码,计算了新认证码的参数,并在假定按照等概率分布来选择编码规则下,计算了成功模仿攻击的概率和成功替换攻击的概率.A construction of Cartesian authentication code from pseudo-symplectic geometry is given. Its size parameters are computed. Assuming that the encoding rules are chosen according to a uniform probability distribution, the probabilities of successful impersonation attack and of successful substitution attack are computed respectively.

关 键 词：认证码 伪辛几何 有限域
