With the rapid rise of the mobile Internet, mobile terminals, as important information communication and data carriers, have played an important role in the information transmission and processing, but the use and storage insecurities of mobile terminal keys have limited their use. Therefore, based on the national secret algorithm standard, this paper proposes and implements a verifiable SM2 threshold signature scheme suitable for mobile terminals. The scheme decentralizes and stores the key, and uses the verification formula to calculate the transfer share in the key generation and digital signature phase, which ensures the security of the digital signature on the mobile terminal, and the performance test shows that the system has good performance and meets the security requirements of the signature algorithm.
