LegRoast is a recent post-quantum signature scheme based on the ‘Legendre PRF’, which considers the quadratic residuosity of a sequence of integers. It adapts the Picnic framework to exploit the homomorphic properties of this PRF in order to arrive at a signature scheme faster and smaller than alternates in round 3 of NIST’s post-quantum standardization process, Picnic and SPHINCS+. In this talk, I'll be going through LegRoast in fine detail, explaining the Legendre PRF, its post-quantum security, how its properties can be exploited for a more efficient zero-knowledge proof and signing scheme, and what the future may hold for the scheme.
