| Abstract |
We consider the problem of authenticating communication over a Myopic Binary Adversarial Channel (MBAC)while maintaining covertness with respect to the myopic adversary. When the main channel between legitimate parties is degraded with respect to the adversary’s channel, we show the existence of an integrated scheme that simultaneously exploits secret keys to ensure covertness and authentication. The main technical challenge we address is showing that authentication may be ensured against myopic attacks when using the low-weight codewords mandated by covert communication
