A Constant-time AVX2 Implementation of a Variant of ROLLO

This paper introduces a key encapsulation mechanism ROLLO+ and presents a constant-time AVX2 implementation of it. ROLLO+ is a variant of ROLLO-I targeting IND-CPA security. The main difference between ROLLO+ and ROLLO-I is that the decoding algorithm of ROLLO+ is adapted from the decoding algorith...
