Scalar Blinding on Elliptic Curves based on Primes with Special Structure

Scott Fluhrer

Abstract

This paper shows how scalar blinding can provide protection against side channel attacks when performing elliptic curve operations with modest cost, even if the characteristic of the field has a sparse representation. This may indicate that, for hardware implementations, random primes might not have as large of an advantage over special primes as previously claimed.
