Research on Security of Multi-access Edge Computing Nodes System Integrated by Blockchain Technology

摘要

This paper introduces the application mode of the multi-access edge computing nodes system (MECNS), and analyzes the needs of the security research of the MECNS. Aiming at the security problems faced by the MECNS in the application of new energy sources such as power plant-grid-load-store system (PPGLSS), etc., the security edge computing node (ECN) is defined, and the architecture of a MECNS with a security mechanism is designed. It is based on public and private key encryption algorithm. The authorization protocol, registration protocol, cancellation protocol and the address query protocol of ECNs are proposed. In this scheme, the confidentiality and security of communication between ECNs are realized through SSL. And on this basis, the blockchain technology is integrated to propose a trusted protection mechanism for edge computing. This architecture and related protocols can ensure the verifiability and non-repudiation of ECN activities.
