In this paper we present an hardware implementation of the RSA algorithm for public-key cryptography. The RSA algorithm consists in the computation of modular exponentials on large integers, that can be reduced to repeated modular multiplications. We present a serial implementation of RSA, which is based upon an optimized version of the RSA algorithm originally proposed by P.L. Montgomery. The proposed architecture is innovative, and it widely exploits specific capabilities of Xilinx programmable devices. As …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
