### 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.
