摘要
This paper presents a 32-bit hardware architecture reduced from the original 128-bit ARIA cryptographic algorithm. The hardware design in this paper is a low-power and compact version of ARIA for mobile environment. We use four S-boxes and modify a diffusion function and its data-path to reduce a hardware size. The proposed 32-bit ARIA needs 63 clock cycles to generate initial values for a round key and 356 clock cycles to encrypt a single message packet. The 32-bit ARIA has 13,893 gates. It is 62.5% smaller than the original 128-bit ARIA. The power consumption is 61.46mW, 9.71%, of the 128-bit version at 71 MHz.
