摘　　要：利用有限域上的酉几何构造一个Cartesian认证码 ,计算了认证码的参数 ,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概率PI 和成功替换攻击概率Ps,为实现一些好的实用认证技术在理论上提供了可靠的基础 ,也给出了在有限域上构造Cartesian认证码的技巧 ;One construction of Cartesian authentication code from unitary geometry is presented.The size parameters of the authentication codes are computed.Assuming that the encoding rules are chosen according to a uniform probability distribution,the probabilities P I and P s of a successful impersonation attack and a successful substition attack,respectively,of this code are computed .This paper strictly provides the basis of theory for the technology of applying authentication system and develops the construction Cartesian authentication skill in finite geometries;At the same time, Wan's results are expanded in this paper.
