In the present study, a chaotic map, substitution-box (S-box) and DNA theory-based image encryption approach is presented. Due to its complex features, including pseudo-randomness and dependence to the initial values and control parameters, chaotic systems have been widely used in image cryptography. Chaotic maps are applied to construct a S-box in confusion stage. In diffusion stage of proposed encryption method, DNA encoding along with three DNA operations namely DNA addition, DNA subtraction, DNA exclusive-or (X-OR)-based approach is suggested. Initial conditions and control parameters of chaotic maps will be considered as a security key. This security key boosts the strength of proposed encryption approach. The adeptness of the proposed approach is justified by comparing with existing techniques in terms of evaluation matrices.

摘要

In the present study, a chaotic map, substitution-box (S-box) and DNA theory-based image encryption approach is presented. Due to its complex features, including pseudo-randomness and dependence to the initial values and control parameters, chaotic systems have been widely used in image cryptography. Chaotic maps are applied to construct a S-box in confusion stage. In diffusion stage of proposed encryption method, DNA encoding along with three DNA operations namely DNA addition, DNA subtraction, DNA exclusive-or (X-OR)-based approach is suggested. Initial conditions and control parameters of chaotic maps will be considered as a security key. This security key boosts the strength of proposed encryption approach. The adeptness of the proposed approach is justified by comparing with existing techniques in terms of evaluation matrices.
