A New Strategy to Design Reconfigurable Rivest–Shamir–Adleman (RSA) Accelerators
International Journal of Circuit Theory and Applications, EarlyView.A reconfigurable FPGA‐based RSA accelerator is proposed using compression‐based modular multipliers combined with pseudomoduli arithmetic. The approach maps modular exponentiation to low‐cost arithmetic domains and applies a correction stage, achieving significant improvements in delay, operating frequency, and delay–area efficiency compared with ...
