| Abstract: | A new construction of cartesion authentication codes is proposed from the set knowledge. Their parameters are derived, and the probabilities of success for the impersonation attack, the substitution attack and order r spoofing attack by the opponent are also computed. These results extend the theorem given in 1997 by Wang Yongchuan and Yang Yixian. |

| Keywords: | authentication codes order r spoofing attack lower bound of information theory |
