Identity-based signature scheme based on quintic residues
Xuedong Dong, Yuan Gao · 2017
We propose a new method to compute a quintic root of a quintic residue. Then we give a new identity-based signature scheme by the method. The scheme is secure against existential forgery on the adaptive chosen message and identity attacks assuming the hardness of factoring. The scheme is the first identity-based signature scheme based on quintic residues.
