A High Bit-Rate Shared Key Generator with Time-Frequency Features of Wireless Channels.
IEEE Global Communications Conference(2017)
摘要
Although pre-shared key schemes are popularly used in securing communication systems, they are impractical in some applications such as ad-hoc communications. This paper proposes a new method for secret key generation between wireless endpoints. In contrast to previous studies, the present method utilizes a joint time-frequency multiscale features of wireless channels, thus yields higher bit-rate and/or larger secret key, as demonstrated in the numerical evaluations and experiments.
