Abstract
An electronic point multiplication device () is provided for computing a point multiplication (kG) on an elliptic curve between a multiplier (k) and a base point (G) on the elliptic curve (E) for use in a cryptographic protocol. The device being arranged to compute from a first set of multiple joint encodings (A) a blinded base multiplier (A,), and a second set of multiple joint encodings (B) multiple blinded auxiliary multipliers (η). The device performs obtains the point multiplication () (kG) of the multiplier (k) and the base point (G) by computing the point addition of the point multiplication of the blinded base multiplier and the base point on the elliptic curve, and the multiple point multiplications of a blinded auxiliary multiplier and an auxiliary point. The blinded base multiplier and auxiliary multipliers may be represented in a plain format during the performing of the elliptic curve arithmetic.
