Topic: 

   A Study of Wiretap Coding in Finite Blocklength Regime

 

Abstract: 

   In this talk, we investigate practical short-blocklength coding for the semi-deterministic binary erasure wiretap channel (BE-WTC). For a better understanding, we first provide a brief introduction to physical-layer security, especially on the secrecy capacity of a general wiretap channel (WTC). We move on to talk about non-asymptotic information theoretic rates, accounting jointly for reliability and secrecy constraints at finite blocklengths, and derive the non-asymptotic theoretical bounds on the secrecy rate for the emi-deterministic BE-WTC, where the main channel is noiseless, and the eavesdropper’s channel is a binary erasure channel. We further provide the achievable secrecy rates of several families of codes and compare them to the second-order secrecy rates, the random coding achievability, and the exact converse bounds.
