FPGA implementation of RSA based on carry save Montgomery modular multiplication
Rupali Verma, Maitreyee Dutta, Renu Vig · 2016
Modular multiplication determines the efficiency of RSA cryptosystem as modular multiplication is core operation in RSA. The efficiency of modular multiplication can be improved by algorithmic improvement. The long operands in Montgomery modular multiplication can be added with carry save adders. Implementation of carry save adders on FPGAs require more area. This paper presents the implementation results of RSA on FPGAs based on carry save Montgomery.
