Abstract
An integrated cryptographic system (24) executes a mathematical algorithm that computes equations for public-key cryptography. An arithmetic processor (22) receives data values stored in a temporary storage memory (14) and computes both the Rivest-Shamir-Adleman (RSA) and Elliptic Curve Cryptography (ECC) algorithms. Multiplication cells (270 and 280) have an INT/POLY terminal that selects a C-register (246) for computing RSA modular exponentiation or ECC elliptic curve point multiplication.
