Method for improving energy efficiency of elliptic curve cryptography algorithm on reconfigurable symmetric cipher processor

The reconfigurable very-long instruction word (VLIW) cipher processor need a large number of instructions and a long execution period when processing the elliptic curve cryptographic algorithm. By adding a modular operation acceleration unit to the cryptographic processor, the energy efficiency of the cipher processor processing the elliptic curve cryptographic algorithm is improved. After synthesis under the 130nm process standard cell library, the experimental results show that the module operation acceleration unit area is 30 Kgate, accounting for 6% of the processor area, and the 256-bit binary domain point multiplication operation time is reduced from 22.8ms to 5.8ms, and the energy efficiency is improved by about 372%.
