[Invited Talk] Information Security in Wireless Communication at Physical Layer Based on Radio Propagation
Hideichi Sasaoka (Doshisha Univ.) RCS2011-10
Abstract (in Japanese) (See Japanese page) 
(in English) As a countermeasure for the risk to eavesdrop by intercept a wireless communication, it is usual to apply the cryptographic techniques such as a public key system and a common key system, which are computationally secure. Information-theoretically secure cryptographic techniques, however, are developing slowly from the theoretical research to the practical approach and are recently interested as a physical-layer security schemes. This paper reviews the radio-layer security schemes such as unconditional secure key agreement and information transmission based on the reciprocity and spatial dependency of radio propagation. This paper also shows the expected attack for these security schemes and the security estimation method.
