Sbox is the most important part of the advanced encryption standard.The implementation of the Sbox determines the per-formance of the AES.Usually,look-up-table method is used in implementation of Sbox.But the utilization of placement of the method is very low.A hardware implementation of the S-Boxes from the advanced encryption standard(AES) is presented.The SBoxes substitute an 8-bit input for 8-bit output and are based on operation in the finite field GF(2m).The result show that a calculation of this function with combinational logic.Compared to traditional methods,the method increases the utilization of placement from 25% to 75%.
