Conclusion ¡°In this paper, we proposed a secure STAR-RIS assisted NOMA-ISAC framework for multi-user and multi-target scenarios. By jointly optimizing base station beamforming, artificial noise, and STAR-RIS coefficients, the proposed design effectively enhances physical-layer security while satisfying sensing requirements. To handle the resulting non-convex problem, a WOA-based metaheuristic optimization method was adopted, achieving fast convergence with low computational complexity. Simulation results confirm clear secrecy performance gains over conventional RIS and random STAR-RIS schemes. Overall, the proposed framework provides a practical and scalable solution for secure ISAC systems in future 6G networks.¡±
