We propose some multivariate cryptosystems based on finite \(BN\)-pair \(G\) defined over the fields \(F_q\). We convert the adjacency graph for maximal flags of the geometry of group \(G\) into a finite Tits automaton by special colouring of arrows and treat the largest Schubert cell \({\rm Sch}\)...
