| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years, with the commercialization of the fifth generation mobile communications system (5G), there has been a growing interest in wireless communications security. This has led to a flurry of research on physical layer security (PLS), which is not encrypted in current wireless systems. In PLS technologies, secret key sharing using channel state information (CSI), which depends on the user's time and location, has attracted much attention because it is information-theoretically secure because it uses a wireless channel that is difficult to predict. However, because CSIs are autocorrelated and time-varying, the randomness of the key deteriorates when the secret key sharing time is shortened in conventional CSI-based key sharing schemes. Therefore, in this paper, we propose a new secret key sharing method using chaos theory that does not degrade the randomness of the key even when the sharing time is shortened, in which the chaos theory exhibits unpredictable and complex behavior when generating the secret key. It is shown through numerical simulations that the proposed method passes the National Institute of Standards and Technology (NIST) randomness evaluation test even when the sharing time is shortened. | |
