In this paper, we investigate the possibility of the use of suprathreshold stochastic resonance system in the physical layer security scheme. The suprathreshold stochastic resonance (SSR) array is used as a preprocessor at the front-end of the legitimate receiver, which reduces the noise in the receiving signal. Analysis in two cases are given, which are (1) the eavesdropper uses the minimum error probability detection and (2) the eavesdropper also uses the SSR-based detection. For (1), as the ambient noise of the channel is non-Gaussian it is shown that even as the legitimate channel is inferior to the eavesdropping channel in a certain range, the mutual information of the legitimate channel is higher than that of the eavesdropper's, which provides the possibility of enlarging the secrecy capacity. For (2), analysis shows that the eavesdropper experiences greater performance deterioration as the legitimate receiver sends the Gaussian interference with timevarying mean. The bit-error-rate simulations testify the above performance analyses.
