Title:
The ElGamal cryptosystem over circulant matrices

Authors: Ayan Mahalanobis

Abstract:

Can one use the discrete logarithm problem in matrix groups, to build a better and secure cryptosystem? We argue, it is indeed the case. This makes the group of circulant matrices suitable and attractive for lightweight cryptography.
