In 1990, Guillou and Quisquater published an article where they described a new digital signature system. Their technique was based on the RSA algorithm. In this paper, we present several modified GuillouQuisquater digital signature protocols. We discuss their security and complexity. These schemes can be seen as alternative signature methods if existing systems are completely broken.
