The wiretap channel is a setting where one aims to provide information-theoretic privacy of communicated data based solely on the assumption that the channel from sender to adversary is "Noisier" than the channel from sender to receiver. It has been the subject of decades of work in the Information and Coding (I&C) community. This paper bridges the gap between this body of work and modern cryptography with contributions along two fronts, namely metrics (definitions) of security, and schemes. The authors explain that the metric currently in use is weak and insufficient to guarantee security of applications and propose two replacements. One, that they call mis-security, is a mutual-information based metric in the I&C style.
