A novel image encryption technique based on H,non chaotic map and S8 symmetric group

The structure of cryptographically resilient substitution boxes (S-boxes) plays a central role in devising safe cryptosystems. The design of chaos-based S-boxes by means of chaotic maps obtained more devotion in current ages. We have suggested novel S-boxes based on the chaotic maps and S-8 symmetric group. We have experimented our chaos-based S-box for image encryption applications and analyze its strength with statistical analyses.
