MOR Cryptosystem and classical Chevalley groups in odd characteristic
In this paper we study the MOR cryptosystem using finite classical Chevalley
groups over a finite field of odd characteristic. In the process we develop an
algorithm for these Chevalley groups in the same spirit as the row-column
operation for special linear group. We focus our study on orthogonal and
symplectic groups. We find the hardness of the proposed MOR cryptosystem for
these groups
Group theory in cryptography
This paper is a guide for the pure mathematician who would like to know more
about cryptography based on group theory. The paper gives a brief overview of
the subject, and provides pointers to good textbooks, key research papers and
recent survey papers in the area.Comment: 25 pages References updated, and a few extra references added. Minor
