Dual-Field Elliptic Curve Cryptography Processor with Countermeasures Against Power Analysis
Xiaoyang Zeng · Journal of Chinese Computer Systems · 2006
A new Elliptic Curve Cryptography (ECC) processor is proposed in this paper, which supports Galois fields GF(p) and GF(2n) arithmetic for arbitrary prime numbers and irreducible polynomials by introducing a dual-field unified algorithm and data-path. To speed up the scalar multiplication, a new technique is used, which is especially useful for the verifying operation of EC Digital Signature Algorithm. At the same time, the EC arithmetic is executed in an anti-attack form. The implementation result based on SMIC 0.18 CMOS technology shows the advantages of this design in the aspects of area, speed and anti-attack performance.
