Implication

Proposed method improves security performance in wireless systems by optimizing multiple reconfigurable intelligent surfaces, highlighting eavesdropping threats.

Key Points

  • The proposed algorithm significantly enhances security performance against eavesdropping in wireless systems.
  • Simulation results indicate a major improvement in secrecy rate over systems using single or dual RIS configurations.
  • Employing alternating optimization, the method effectively addresses non-convex optimization for beamforming and phase shifts.
  • Real-world challenges like imperfect channel state information may impact the security efficacy of multi-RIS setups.
