Abstract:Galois field computations abound in many applications, such as in cryptography, error correction codes, signal processing, among many others. Multiplication usually lies at the core of such Galois field computations, and is one of the most complex operations. Hardware implementations of such multipliers become very expensive. Therefore, there have been efforts to reduce the design complexity by decomposing the Galois field GF(2 k ) as GF ((2 m ) n ) where k = m × n. Such a decomposition introduces a hierarchic… 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.
