LI Ling-fan · Journal of Chinese Computer Systems · 2007
The paper analyzes WheelChange and KeyExpansion of Rijndael algorithm and puts forward to use the matrix to optimize Rijndael algorithm,then WheelChange and KeyExpansion are converted into look-up table and the optimized flow chart of Rijndael algorithm is given. According to the characteristics of the table,the hardware circuit design of Rijndael algorithm is completed by making use of saving resources of FPGA.
