Wave is a family of PSF (Preimage Sampleable Functions) based on error correcting codes. It allows the design of a hash-and-sign digital signature scheme whose security provably reduces to two computational assumptions from coding theory.

The Wave paper “Wave: A New Family of Trapdoor One-Way Preimage Sampleable Functions Based on Codes” will be presented at the Asiacrypt 2019 conference and will appear in the proceedings. It also is available on line as a preprint

Its authors are Thomas Debris-Alazard, Nicolas Sendrier, and Jean-Pierre Tillich.
