The discrete logarithm problem in the group of non-singular circulant matrices

Ayan Mahalanobis

Abstract: The discrete logarithm problem is one of the backbones in public key cryptography. In this paper we study the discrete logarithm problem in the group of circulant matrices over a finite field. This gives rise to secure and fast public key cryptosystems.

Category / Keywords: public-key cryptography / MOR cryptosystems, discrete logarithm problem, circulant matrices
