A Blockchain-based Protocol for Power Data Preservation in Ping Dingshan vs. Wang Case

power companies, the data collected by smart meters on electricity consumption is of vital interest. In 2019, Wang had a dispute with Ping Dingshan. They came into disagreement regarding the amount of electricity consumed, which was a difference of 1334 kWh. It was not settled until 2021. To avoid the above problem, smart meters could upload power information to the blockchain. In this paper, we improved the authentication protocol key proposed by Zhang and proposed a new scheme for uploading the power information from smart electricity meters, which ensures the integrity, confidentiality and authentication of the power information. At the same time, the proposed scheme is unbalanced for the computing capability of both communication parties, and can effectively reduce the burden of the server.
