摘　　要：本文利用有限域上1维向量子空间构造了一个Cartesian认证码,并计算了该认证码的参数│S│,│E│,│M│,进而在假定编码规则按照均匀的概率分布被选取的情况下,分别计算了成功模仿攻击概率PI和成功替换攻击概率PS。In this dissertation,we use 1-dimensional vector subspace over Finite Fields to construct Cartesian Authentication Code and compute the paramaters of the code. Moreover,we assume that the encoding rules are chosen according to a uniform probability distribution. The and ,which denote the largest probabilities of a successful impersonation attack and of a successful substitution attack respectively,of these code are also computed.
