Modular multiplication is a key operation in public key cryptosystems like RSA. Among modular multiplication methods, Montgomery modular multiplication is an efficient algorithm suitable for hardware implementation. In this paper, a Modified Montgomery Modular Multiplication design is proposed with carry save adder architecture and parallel simplified quotient computation for the next iteration...

Encryption and decryption in RSA are done by modular exponentiation which is achieved by repeated modular multiplication. Hence efficiency of modular multiplication directly determines the efficiency of RSA cryptosystem. This paper designs a Modified Montgomery Modular Multiplication in which addition of operands is computed by 4:2 compressor. The basic logic operations in addition are partitio...

Modular design is the based on independent and connectable modules to achieve product variety. It an ideal tool that could facilitate inclusion of prosumers in creative process. However, its evolution has focused development not end users. The creation a new modular model for respond their needs while exploiting advantages modularity. present work analyzes applicability prosumer scope defines g...
