document: Efficient cellular automata based versatile multiplier for GF -LRB- 2/sup m / -RRB- In this paper , a low-complexity programmable cellular automata -LRB- PCA -RRB- based versatile modular multiplier in GF -LRB- 2/sup m / -RRB- is presented . The proposed versatile multiplier increases flexibility by using the same multiplier in different security environments , and it reduces the user 's cost . Moreover , the multiplier can be easily extended to high order of m for more security , and low-cost serial implementation is feasible in restricted computing environments , such as smart cards and wireless devices
