The RSA algorithm was recognized as the asymmetric encryption signature algorithm in PBOC2.0 specifications. Since the Elliptic Curve Cryptosystem(ECC) is popular in smart card platform, this paper ...

In this article, we present a memory-efficient variant of Tunstall's random-order exponentiation algorithm, making it applicable to modular exponentiations in (Z/NZ)* (for instance, the RSA ...
