Abstract :
In order to make the typical Montgomery´s algorithm suitable for various lengths RSA, this paper proposes a scheme for an expandable RSA coprocessor. This design allows for cascading the hardware of process elements when larger modulo are required. The proposed design uses optimized Montgomery´s modular multiplication algorithm. The proposed architecture has distinctive features, i.e. not only the computation speed is significantly fast but also the hardware overhead is drastically decreased
