Research on Blockchain Reconciliation Applications of Intelligent Charging Pile Platforms
Qingrong Zheng, Jianli Zhao, Jiani Xiang · 2021
To solve the problem of low reconciliation efficiency of city-level charging pile platforms, we propose a homomorphic encryption-based blockchain smart contract reconciliation application. Blockchain technology is used to achieve order recording, bill reconciliation, and synchronization of data. At the same time, homomorphic encryption technology is used to protect the data privacy in the blockchain system so that the order data can be not only open and transparent but also privacy preserved. In this study, three different kinds of fully homomorphic encryption technologies are used for performance comparison, including a new polynomial homomorphic encryption algorithm based on coefficient mapping transformation. Experimental data show that the new algorithm has great performance improvement in all operations.
