Hongyi Lu · Computer Engineering and Science · 2007
Message integrity can be achieved by the hash functions of cryptography,and hardware implementations are essential to high-performance requirements in special applications such as trusted computation.In this paper, according to the similarity of the widely-used hash algorithms,custom reconfigurable function units are developed.By integrating these units into a transport triggered architecture,a reconfigurable processor TTAH is implemented.The results of mapping several hash algorithms to TTAH show that TTAH is faster and more area-efficient compared to the fine-grained reconfigurable architecture,and it can support these hash algorithms with little overhead compared to ASIC.
