【Abstract】 Authentication codes play an important role in modern communication.Authentication means that the receiver can identify the information,which is an essential technology avoiding the attack of others.A construction method of Cartesian authentication codes is presented and the parameters are computed.Moreover,assuming that the encoding rules are chosen,Pl and PS,which denote the largest uniformly distributed probability of a successful impersonation attack of these codes and of a successful substitution attack respectively,are also computed.更多还原
