| Abstract: | Multi-receiver Authentication Codes with Secrecy are investigated in this pa- per. An information-theoretic lower bound for the probability of successful deception for a spoofing attack of order r is obtained. By use of partially ballanced t-designs and special block designs, the combinatorial characterization of multi-receiver authentication codes that can achieve the lower bound is described. |
