利用有限域上辛几何构作Cartesian认证码

利用有限域上的辛几何构作了一个Cartesian认证码,并计算了这个码的参数。进而,假定编码规则按照均匀的概率分布所选取,计算出了该码被模仿攻击成功的最大概率P1和被替换攻击成功的最大概率P3。

The Construction of Cartesian Authentication Codes from Symplectic Geometry

A consturction of Cartesian authentication codes from symplectic is presented. The parameters of the code are computed. Moreover,assumed that the encoding rules are chosen according to a uniform probability destribution, the P1 and Ps which denotes the largest probabilities of a successful impersonation attack and,of a successful substitution attack respectively, and these codes are also computed.
