Alternative Equations for Guillou-Quisquater Signature Scheme
Jaouad Ettanfouhi, Omar Khadir · International Journal of Computer Network and Information Security · 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.
