Abstract:

Electric vehicle charging platform is a crucial part of smart grid, more and more users use the charging pile to charge their electric vehicle, the charging platform will store a large amount of transaction data. In the existing charging pile sharing platform, the user’s transaction data is uploaded to a trusted central database for storage, But this centralized storage method is highly vulnerable to malicious attacks, causing single point of failure and important transaction data security problems such as malicious tampering, and thus may cause a large number of user privacy information to leak. In response to these problems, this paper proposes to use the blockchain technology to select a number of charging stations in the electric vehicle charging platform as data center nodes to construct a transaction data storage system. The users can encrypt personal transaction data and control data usage rights. The data center nodes use a consensus mechanism to decentralized store encrypted data in a synchronized manner. The security analysis shows that the designed data storage platform can safely store data.
