Abstract

Physical layer cryptography is the cryptographic technique which realizes the information-theoretically secure message transmission and key establishment by exploiting physical properties of transmission channels. In this paper, we give an outline of fundamental model for physical layer cryptography and present the main result of channel estimation experiment toward the physical layer cryptography in free space optical communication which is carried out by Quantum ICT Advanced Developed Center.
