ABSTRACT

This paper proposes an efficient SM2 digital signature. The batch verification algorithm is especially suitable for application scenarios that require verification of a large number of digital signatures such as electronic money. The algorithm does not verify immediately after each signature, but verifies multiple signatures at the same time. Because in the SM2 digital signature verification process, the dot multiplication operation is a very time-consuming operation, the batch verification algorithm significantly shortens the entire verification process by reducing the time-consuming dot multiplication operation in the verification process, and greatly improves the verification efficiency. Experimental data shows that in the case of the same number of messages, the efficiency of the batch verification algorithm is much higher than the efficiency of a single verification algorithm. For example, when the number of signatures reaches about 1 million, a single verification algorithm takes about 1 hour, while a batch verification algorithm only needs 2 seconds.
