Wiretap channels form the most basic building block of physical-layer and information-
theoretic security. Considerable research work has gone into the information-theoretic,
cryptographic and coding aspects of wiretap channels in the last few years. The main goal of
this tutorial article is to provide a self-contained presentation of two recent results-one is a
new and simplified proof for secrecy capacity using channel resolvability, and the other is
the connection between semantic security and information-theoretic strong secrecy.
