A Method of Data Distribution and Traceability Based on Blockchain

Abstract

In view of the privacy and particularity of power data, this paper proposes a traceability encryption data distribution method based on encryption technology in power system, including data distribution based on encryption technology in different storage modes and traceability mechanism suitable for different leak scenarios, so as to improve the traditional data distribution centralized degree, unclear rights allocation, low distribution efficiency and complex traceability conditions. This method uses league chain to construct block chain service, formulates different encrypted data forwarding schemes according to different storage modes of data files in the sender, adapts different data leakage traceability strategies according to different scenarios of data leakage in various forwarding schemes. A traceability, tamper-free, open and transparent shared traceability model is established. It ensures the safe transmission of power data and the traceability of data, and realizes the effective supervision of data sender and data receiver, so as to ensure the integrity of data distribution.
