Abstract: With the acceleration of new power systems, there has been increasing emphasis on the need for secure power infrastructure. The implementation of 5G technology in power systems has leveraged wireless communication for the transmission of critical data. While this advancement has enhanced network accessibility, it has concurrently heightened security vulnerabilities. At present, the scheme to bolster the secure communication capabilities of power terminals through a fusion of quantum cryptography and lightweight identification technology is grappling with practical deployment challenges. To address this predicament, we introduce a novel quantum key-based lightweight authentication architecture for local communication networks. By leveraging a secure encryption chip in conjunction with lightweight authentication key technology, the proposed architecture facilitates efficient and secure connectivity among a multitude of terminals in local communication settings. A comprehensive security analysis shows that the proposed solution has strong security capabilities to meet the requirements of new power systems.

Keywords: local communication; quantum cryptography; secure chip; lightweight authentication key technology; authentication.
