摘要 利用群在集合上的共轭作用,给出了一种由2-Jordan型幂零矩阵构造Cartesian认证码的新方案,计算了相关参数,并在假定编码规则按等概率分布选取时分析了模仿攻击和替换攻击成功的概率. We describe a new construction of Cartesian authentication codes from nilpotent matrices with the 2-Jordan normal form by the ″conjugate action″ of a group on a set, and some its size parameters are computed. Moreover, assume that the encoding rules are chosen according to a uniform probability distribution, the largest probabilities of a successful impersonation attack and of a successful substitution attack of these codes are also computed.
