Distributed Network Data Security Protection for SG-eIoT

Abstract

With the continuous advancement of power system reform, grid enterprises relying on new technologies such as big data, cloud computing, artificial intelligence, internet of things (IoT) and blockchain are transforming towards more open energy internet enterprises, which brings more challenges to network security. The construction of SG-eIoT has promoted the circulation of data in all aspects of the system, cleaning up the barriers of data islands and effectively improving the operational efficiency of power company. However, due to the large scale of data access points, complex business operations, and huge amount of upstream and downstream enterprises in the industry chain, security risks may exist in the information circulation process such as being tampered and untrustworthy. Aiming at the problem of information security and credibility in the distributed network environment of power enterprises, this paper studies the application of blockchain technology in business information flow, and constructs a new data management mode of weak service connection to strong data interoperability based on the characteristics of blockchain technology, such as non-tampering property, collective maintenance and transaction non-repudiation, which achieves accurate data protection, and fully spports the construction of world-class energy internet company with excellent competitiveness.
