A Centralized Blockchain-based Data Security System for Electrical Energy against Attacks

摘要

Electric power networks are evolving rapidly across the globe. In order to deliver energy to the end users, traditional systems had to rely heavily on a centralized network, which led to increased cyber-attacks against the power systems, causing instability and serious problems such as blackouts. In this paper, by providing high protection to the modern power system using block chain technology, the outlined triggers can be solved by maintaining essential records through the decentralized ledger that magnifies the firmness of the electric power system. The key operational data are encapsulated in the form of blocks and hashed to create a unique value. The paper flow begins from the collection of information where the basic data is obtained. The encryption and decryption of the information is then carried out using the SHA-256 algorithm. In addition, there is a method of data validation with the assistance of the Byzantine Fault Tolerance algorithm, which allows all nodes to achieve consensus agreement. In addition, after efficient validation of the blocks by the miners who validate it using mathematical problem, the linking of blocks occurs to find the nonce, which is nothing but the solution for adding up the consecutive blocks. Finally, attack classification takes place where the daily electrical use dataset is pre-processed, conditioned and evaluated.
