A modern signature scheme with message recovery: Abe--Okamoto signatures with EdDSA elements

Satō Shinichi

Abstract

This paper revisits the Abe--Okamoto signature scheme to present a version of their signature scheme augmented with modern best practices, with major influences taken from EdDSA. Implementation guidance is given on how to reuse existing Ed25519 code.
