| Abstract | SM2 has been fully studied on x86-64 architecture, but its optimization on ARMv8-A architecture is inadequate. In this work, we propose the following optimizations to fill this gap: for the modular multiplication/squaring of p and n in SM2, we optimize Montgomery modular multiplication/squaring by leveraging the numerical characteristics of p and n; for the modular inversion of p and n in SM2, we derive and implement a faster modular inversion algorithm based on Fermat's little theorem; for fixed-point and unknown-point scalar multiplication, we implement window algorithms with a window width of 7 and 5, respectively; for the calculation of s during the signature generation process, we replace a modular multiplication of n with a cheaper modular addition/subtraction of n. After integrating the optimizations mentioned above into OpenSSL (3.0.0-beta1), the benchmark on the HUAWEI Cloud Kunpeng 920 computing platform shows that the performance of SM2 signature generation is accelerated by 8.7 times; the performance of SM2 signature verification is accelerated by 3.5 times. Meanwhile, on the mobile device Raspberry Pi 4 platform, the performance of SM2 signature generation is accelerated by 9.7 times; the performance of SM2 signature verification is accelerated by 3.4 times. |
