Parallel algorithms and systolic array designs for RSA cryptosystem
C.N. Zhang, H.L. Martin, David Y. Y. Yun · 2003
Two algorithms for computing very large integer modular exponentiation are proposed. One is based on a recording technique that significantly reduces the total number of modular multiplications. The second is parallel algorithm that can be implemented by two parallel processors and achieves optimal performance. Two corresponding systolic array designs are developed. The main advantage of these systolic architectures is to provide a potentially higher throughput for a large number of computations, namely, encryptions and decryptions in an RSA cryptosystem.>
