RSA Apparatus and Method for Integrated Hardware Implementation of Elliptic Curve Cryptography and RSA Public-key Cryptosystem

摘要

The present invention relates to an arithmetic unit and method for integrally implementing an elliptic curve cryptosystem and an RSA public key cryptosystem, and more particularly, to an arithmetic apparatus and method for integrally implementing an elliptic curve cryptosystem and an RSA public key cryptosystem using scalar multiplication of elliptic curve cryptosystem and modular exponentiation operation of RSA (Rivest-Shamir-Adleman) A first memory for storing a modulo value necessary for a finite field operation; a second memory for storing parameters and intermediate result values used for elliptic curve cryptosystem and RSA cryptosystem; And a control unit for controlling the memory and the second memory.
