英文摘要Elliptic curve encryption (ECC) has been widely used in public key cryptography, and modular multiplicationis one of the core operations of elliptic curve encryption. This paper presents a low-cost high-speed parallelmodular multiplication implementation based on SM2. Using the characteristics of the prime (??256), the two-step multiplication and reduction of modular multiplication are performed in parallel. The 8-part karatsubaalgorithm is used in multiplication. In the process of performing multiplication, in order to reduce theconsumption of multiplier resources, the karatsuba algorithm is used to improve the ordinary multiplier. Thecontrol signal????= 0/1is used to control the multiplier to perform ordinary multiplication or karatsubaalgorithm multiplication. Then the multiplier is reused. 4 improved 32-bit multipliers are used in complete256-bit modular multiplication. Experiments show that on the 100 MHz Artix-7 FPGA hardware platform, only12K LUTs are needed, and a modular multiplication operation can be completed in0.09 mu s. Comprehensivetime and area, our design has certain advantages
