Abstract

Considering the issues of communication and sensing securities for the reconfigurable intelligent surface (RIS) enabled integrated sensing and communication system

a joint design for the transmit covariance matrix and the reflection matrix of the RIS is proposed to maximize the ergodic secrecy rate under the constraints of legal sensing signal-to-noise ratio (SNR)

eavesdropper sensing SNR

transmit power

and the constant modulus for the reflection matrix of the RIS. Firstly

the asymptotic ergodic secrecy rate lower bound and the asymptotic sensing SNRs are derived by exploiting the large dimensional random matrix theory. Then

based on the statistical channel state information

the optimal closed-form optimal solution for the transmit covariance matrix is derived by exploiting the modified water-filling algorithm and the first-order Taylor series expansion

and sub-optimal the reflection matrix of the RIS is obtained by employing the barrier method and the projected gradient ascent method. Finally

numerical simulations validate the accuracy of the large-system analysis and the superiority of the proposed method.
