%0 Journal Article %T MOR Cryptosystem and classical Chevalley groups in odd characteristic %A Ayan Mahalanobis %A Anupam Singh %J Computer Science %D 2014 %I arXiv %X 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. %U http://arxiv.org/abs/1408.6340v1
