Symmetric block ciper algorithm consists of a chains of operations such as permutation and substitution. There exists four kinds of operation mode, CBC, ECB, CFB, and OFB depending on the operation paradigm. Since the final ciper text is obtained through the many rounds of operations, it consumes much time. This paper proposes a pipelined design methodology which can improve the speed of crypto operations in ECB mode. Because the operations of the many rounds are concatenated in serial and executed concurrently, the overall computation time can be reduced significantly. The experimental result shows that the method can speed up the performance more than ten times.
