leveraging quantum key distribution for data security in distributed energy resources

The rapid proliferation of distributed energy resources (ders) introduces substantial challenges in securing the vast volumes of data exchanged within these decentralized networks. while traditional cryptographic methods remain effective, they are increasingly susceptible to the threats posed by quantum computing, particularly in the realm of key distribution. this paper proposes quantum key distribution (qkd) as an advanced solution, harnessing the principles of quantum mechanics to deliver unparalleled security for cryptographic key establishment. we explore the application of qkd within der systems, addressing specific constraints such as limited bandwidth, resource-constrained devices, and dynamic network topologies. we assess the feasibility of incorporating qkd into existing communication frameworks by evaluating the bb84 qkd protocol and its integration with der infrastructures. our study also considers practical aspects such as scalability, interoperability, and cost-effectiveness. the findings reveal that qkd achieves a practical key efficiency of approximately 50%, underscoring its suitability for der applications. moreover, qkd provides robust security features, including minimal error rates in noiseless environments, manageable error rates in noisy conditions, and strong resilience against eavesdropping. these capabilities ensure the integrity and confidentiality of data within der networks, marking a significant advancement in secure communication technologies.
