Dynamic Countermeasure Against the Zero Power Analysis
Jean-Luc Danger and Sylvain Guilley and Philippe Hoogvorst and CÚdric Murdica and David Naccache
Abstract: Elliptic Curve Cryptography can be vulnerable to Side-Channel Attacks, such as the Zero Power Analysis (ZPA).
This attack takes advantage of the occurrence of special points that bring a zero-value when computing a doubling or an addition of points.
This paper consists in analysing this attack.
Some properties of the said special points are explicited.
A novel dynamic countermeasure is described.
The elliptic curve formulæ are updated depending on the elliptic curve and the provided base point.
Category / Keywords: public-key cryptography / Elliptic Curve Cryptography, Side-Channel Analysis, Zero Power Analysis, Zero-Value Points, Dynamic Countermeasure, Jacobi Symbol.
