The parametrization of the action of the modular group P S L ( 2 , Z ) for the triangle groups is extended for Δ ( 2 , 3 , k ) to the finite generalised triangle groups 〈 u , v | u 2 = v 3 = w k = 1 〉 where w = u v u v u v 2 u v u v 2 . Also, based on the resulting parametric equations , the authors have presented an audio encryption approach in this study. The extremely secure S-Box, which is then utilised to encrypt audio signals , is built using parametric equations . Utilising several audio sources, the effectiveness of the current approach is assessed. According to the simulation specially differential analysis average NSCR 99.96% and average UACI 33.33% as well as comparison results, the recommended method might prevent cryptographic vulnerabilities and produce reliable encryption results.
