ePrint Report: Vortex : Building a Lattice-based SNARK scheme with Transparent Setup

Alexandre Belling, Azam Soleimanian

We present the first transparent and plausibly post-quantum SNARK relying on the Ring Short Integer Solution problem (Ring-SIS), a well-known assumption from lattice-based cryptography. At its core, our proof system relies on a new linear-commitment scheme named Vortex which is inspired from the work of Orion and Brakedown. Vortex uses a hash function based on Ring-SIS derived from “SWIFFT" (Lyubashevsky et al., FSE08). We …
