Abstract:The hash functions are applied in the communication integrity and signature authentication. There are so many secure communication protocols which involve various hash algorithms of different security level. This paper presents a reconfigurable hardware design to support different protocols, which use SHA-1 or MD5 hash algorithm. Because it implements two algorithms with one set of hardware and only uses two 32-bits registers in the data-path, this design is also an ultra low cost solution for portable communi… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
