Abstract

Cyber-physical systems (CPS) are critical components in industrial control, automation, and real-time decision, making, where they must frequently rely on cooperative relaying to be able to communicate reliably and with low latency. Nevertheless, advancements in quantum computing capabilities pose a threat to the cryptographic measures traditionally used in these networks. This paper explores the possibility of combining post-quantum secure protocols with the cooperative relaying architectures of CPS environments. We have run simulations to measure the effectiveness of these security measures by monitoring various parameters such as the ability to resist eavesdropping, the efficiency of secure key distribution, throughput, latency, energy consumption, and channel capacity. Our findings indicate that post-quantum technology can be instrumental in fortifying communication security without compromising the efficacy of key management and spectral utilization. The suggested approach also shows excellent flexibility when subjected to realistic traffic scenarios, thereby allowing data transmission with minimal delay required by time, critical control applications. Although post-quantum schemes introduce moderate additional energy overhead, the improvement in long-term security resilience outweighs the cost. The findings confirm that quantum-resilient cooperative relaying provides robust protection for Industrial IoT, smart grid infrastructures, and autonomous control networks against future quantum-enabled attacks, making it a viable foundation for next-generation secure CPS communication.
