Abstract:

Elliptic Curve Cryptography (ECC) has become widely deployed in embedded cryptographic devices. However, power analysis attacks may retrieve secret keys by exploiting the power consumption of ECC devices. This paper proposes a countermeasure with balanced operation procedure of point doubling and addition during the scalar multiplication implementation of ECC algorithms. Experiment results on smart cards demonstrate this balanced method can largely enhance the secure against side-channel attacks.

I. Introduction

Elliptic curve cryptography (ECC) was first proposed by Miller and Koblitz in 1985 [1]. In virtue of no subexponential algorithms known for the elliptic-curve discrete-logarithm problem (ECDLP), ECC provides equivalent security strengths with shorter keys compared to other public-key cryptosystems. Due to this advantage, ECC has acquired wide attention in academia as well as industry.
