Abstract: To meet the strategic demand for independently controllable national information security and to ensure algorithm transparency and security, a high-performance parallel acceleration method for the domestic public key cryptographic SM2 digital signature algorithm based on domestic GPU was proposed. Firstly, low-level functions for field operations were designed to optimize the efficiency of finite field arithmetic, with two-round carry resolution adopted in modular reduction to resist timing attacks. Then, point addition and point doubling were implemented using Jacobian coordinates, leveraging register and global memory features, and offline/online precomputation tables were introduced to enhance scalar multiplication efficiency. Finally, experimental design was carried out based on the characteristics of the Hygon deep compute unit (DCU) platforms, achieving high-performance SM2 signature and verification with throughput of 6 816 kops/s and 1 385 kops/s, respectively. Results demonstrate the feasibility and effectiveness of implementing clemestic public key cryptographic SM2 based on domestic GPU, providing crucial support for national information security autonomy.
