Security Enhancement Approaches to Wireless Communications Using Secret Sharing and Signal Processing in Physical Layer

Abstract

Secret sharing is a method of protecting information securely. The information is divided into n shares, and the information is reconstructed from any k shares but no knowledge of it is revealed from k-1 shares. Physical layer security is a method of yielding a favorable receive condition at an authorized destination terminal in wireless communications. In this study, we explain the fundamentals of secret sharing and physical layer security, and approaches to enhancing the security of wireless communications based on secret sharing and signal processing in physical layer security.
