基于区块链的共享充电桩安全监管方案

共享充电桩可缓解当前电车充电难的现状。然而，基于第三方平台的共享充电桩平台面临着信任问题；而基于区块链的共享充电桩平台虽可提供信任环境，但缺乏对用户、桩主、充电量等信息核查。为解决以上问题，提出了一种基于区块链的共享充电桩安全监管方案。该方案通过基于双链的共享充电信任模型，安全地存储用户、桩主或运营商的关键信息，并在该模型上设计穿透式监管方案，向上核查用户、桩主或运营商的身份，向下核查充电量、充电速度等信息正确性。实验评估表明，该方案能够以不大的开销提高平台的安全性。

Security supervision scheme of shared charging pile based on blockchain

Sharing charging piles can alleviate the current situation of difficult charging of electric vehicles. However, the shared charging pile platforms based on the third-party platform face the problem of trust; although shared charging pile platforms based on the blockchain can provide a trust environment, these platforms lack verification of users, pile owners, charging capacity and other information. In order to solve the above problems, this paper proposed a security supervision scheme of shared charging pile based on blockchain. The scheme could securely store the key information of users, pile owners or operators through the shared charging trust model based on double chain. It designed a penetrating supervision scheme on the model to check the identity of users, pile owners or operators upward and the correctness of information such as charging capacity and charging speed downward. Experimental evaluation shows that the proposed scheme can improve the security of the platform with a small overhead.
