The secure hash algorithm of SHA-256 is widely used in digital encryption and signature.A new hardware structure was proposed to implement the algorithm fast in order to meet the speed requirement in all kinds of applications.The new scheme was obtained by applying suitable transformation of the algorithm.According to it,the balanced four step pipeline could be implemented in hardware.Thus the speed performance was improved.Synthesized with the SMIC technique library featuring 0.18 μm process,the proposed core achieved a throughput of 2.89 Gb/s.To our knowledge,it outperformed the other counterparts.
