| Abstract: | 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. |
