Data protection method for charging pile based on blockchain technology
Guangcun Wei, Lan Gao, Qing Li · 2019
Aiming at the lack of information maintenance technology after the charging piles left the factory, the double encryption technology in the data transmission process causes a lot of computing power and storage space waste. A data protection method for charging piles based on blockchain technology is proposed. In order to ensure the security and integrity of the data, the blockchain technology is used to protect all the processes after the charging pile left the factory. The scalar multiplication of elliptic curve encryption algorithm is optimized and improved. Represent the random number as a binary number, reducing the amount of computation of the operation. In addition, in order to improve the efficiency of elliptic curve encryption algorithm, the Hamming weight is used to reduce the inverse operation.
