摘要
Optimized implementation of computationally intensive cryptographic transformation is an area of active research, mainly focused on Advanced Encryption Standard (AES). Byte substitution implemented using substitution boxes (S-boxes), is the main transformation in AES which strains the enabling embedded platform, e. g., Field Programmable Gate Arrays. We represent a novel clocking technique enabling optimized implementation of Byte Substitution that enhances processing speed and reduces the area required for S-boxes on Xilinx FPGA Block RAM (BRAM).
