Here is a more detailed description of the algorithm proposed in 1. This algorithm simultaneously uses two cryptographic procedures: encryption using a generalization of the Markovski algorithm 2 and encryption using a system of orthogonal operations. In this paper, we present an implementation of this algorithm based on T-quasigroups, more precisely, based on medial quasigroups.
