摘要

This paper investigates the achievable secrecy rate region of the Gaussian two-way wiretap channel,which describes the simultaneous secure two-way transmission of a confidential message.Through adjusting the time-sharing factor and the rate at which the random secret key is fed back,the allocation and optimization for the secrecy rates of two-way communication are achieved.Under peak and average power constraints,the achievable secrecy rate regions of the two-way communication are derived respectively.
