Abstract:

A fast advanced encryption standard (AES) encryption method based on one lookup table for resource-constrained industrial wireless network was presented. A 512-Byte lookup table was constructed by compressing and optimizing the lookup table of the widely used method based on four 1KB lookup tables, It decreases the storage of lookup table and the overhead consumed by the GF(28) multiplications; the round function was optimized as well, decreasing the additional operations caused by the compressed lookup table. Experiment shows that this method saves 72% at the cost of 43% more computation time and power compared with the method based on four 1-KB lookup tables; and saves 55% computation time and 61% power at the cost of 2.5 folds storage consumption compared with the method based on the accelerator on radio chips.
