Alternative Equations for Guillou-Quisquater Signature Scheme

By J. Ettanfouhi O. Khadir

DOI: https://doi.org/10.5815/ijcnis.2016.09.04, Pub. Date: 8 Sep. 2016

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 Guillou-Quisquater digital signature protocols. We discuss their security and complexity. These schemes can be seen as alternative signature methods if existing systems are completely broken.
