Attacking M&M Collective Signature Scheme

Michal Rjaško and Martin Stanek

A collective signature scheme aims to solve the problem of signing a message by multiple signers. Recently, Moldovyan and Moldovyan [1] proposed a scheme for collective signatures based on Schnorr signatures. We show some security weaknesses of the scheme.
