A New Directed Signature Scheme On A General Linear Group Over A Group Ring

Authors : Makhlouf Sassia . Guenda Kenza . Gulliver T. Aaron .

Abstract

In this work, we propose a new directed digital signature scheme over a group ring whose security relies on the hardness of the discrete logarithm problem and the factorization search problem. This scheme is efficient as it requires very few operations for both signing and verifying signatures. Further, the security of the proposed scheme is examined.
