The Arbitrarily Varying Wiretap Channel—Secret Randomness, Stability, and Super-Activation
The Arbitrarily Varying Wiretap Channel—Secret Randomness, Stability, and Super-Activation
We define the common randomness-assisted capacity of an arbitrarily varying wiretap channel (AVWC) when the eavesdropper is kept ignorant about the common randomness. We prove a multi-letter capacity formula for this model. We prove that, if enough common randomness is used, the capacity formula can be given a single-shot form …
