A digital audio data protection method using parametric action of generalised triangle group on GF(28)

The parametrization of the action of the modular group PSL(2,Z) for the triangle groups is extended for Δ(2,3,k) to the finite generalised triangle groups 〈u,v|u2=v3=wk=1〉 where w=uvuvuv2uvuv2. Also, based on the resulting parametric equations, the authors have presented an audio encryption approach...
