Information spectrum approach to strong converse theorems for degraded wiretap channels
We consider block codes for degraded wiretap channels in which the legitimate receiver decodes the message with an asymptotic error probability ε but the leakage to the eavesdropper vanishes. For discrete memoryless and Gaussian wiretap channels, we show that the maximum rate of transmission does not depend on ε ϵ …
