两类笛卡尔认证码的构造

利用有限域上的2v 2维伪辛空间中的子空间构造了两类笛卡尔认证码,并且计算了它们的参数,假设编码规肘是按照一种均匀概率分布选择的,则模仿攻击成功的概率P_I和替换攻击成功的概率P_S也被计算。

Construction of Two Classical Cartesian Authentication Codes

Two classical cartesian authentication codes are constructed from the (2v 2)-dimensional pseudd symplectic space over finite fields.and their size parameters are armputed.suppose that the encoding rules are chosen according to a uniform probability distribution, the probabilities P1 and Ps of a successeful impersonation attack and a successful substitution attack ,respeectively,of these codes are also computed.
