| Abstract: | Digital signature scheme Aigis-sig,constructed on ideal lattice,takes the advantages of high efficiency,short signature length and resistant to quantum attack,etc.An optimized modular multiplication arithmetic component was constructed and a compact hardware architecture for polynomial operation over a ring based on number theory transformation(NTT)algorithm for Aigis-sig was designed.Besides,based on this architecture,software/hardware co-design and implementation for Aigis-sig scheme on FPGA platform in cryptography was proposed.Experimental results show that the speed of signature phase and verification phase are increased by about 26% and 17% respectively,compared with the pure software implementation on Xilinx Zynq-7000 SoC platform when CPU clock frequency and hardware clock frequency are set as 666.66MHz and 150 MHz respectively. |
