Abstract

In this paper, we introduce two double-IRS strategies to enhance proactive eavesdropping, namely Double-IRS Enhancing Strategy (DES) and Double-IRS Enhancing-Jamming Strategy (DEJS). In the former strategy, both cooperative IRSs reflect the incident signal passively. In the latter strategy, one IRS performs passive reflection while the other IRS acts as a passive jammer to modulate the incident signal into the jamming signal to deteriorate the suspicious link. Based on these two strategies, the semidefinite relaxation (SDR) technique and the bisection search method are applied to optimize the reflection coefficients at two IRSs, aiming at maximizing the effective eavesdropping rate. Finally, numerical evaluations are conducted to verify the effectiveness of our proposed schemes.
