摘要
利用有限域上酉几何构作了两类Cartesian认证码,计算了这些码的参数。当编码规则按等概率分布选取时,计算出敌方成功的模仿攻击概率和成功的替换攻击概率。
Two constructions of Cartesian authentication codes from unitary geometry are given, and the parameters are computed. Assuming the encoding rules are chosen according to a uniform probability distribution, the probabilities of successful impersonation attack and substitution attack of the opponent are also computed.
