Abstract
DNA computing has prevailed in the field of cryptography. DNA cryptography uses DNA as an information transporter and gets benefit from biotechnology in order to achieve encryption. Encryption character algorithm proposed by Kang et al relying on pseudo-DNA operation, However, DNA encryption methods have defects such as expensive experimental equipment, complex operation and difficult to understand its biotechnology and remains cannot be effectively applied in encryption field. Also the chaos theories can generator dynamic system with random numbers. In this paper; a design new approach for encryption image was suggested depending on proposal DNA computing such as (coding, decoding) with multi-operation in festiel structure to increase more complexity when an attacker tries image retrieval. When used NLFSR as random generate system to mixing to increase complexity also was proposed new idea to generated secret key. A performance analysis in measurement test between the original image and encryption image was evaluated, the values rustle is big to depend on no correlation for a pixel in original and cipher image. Another test between plain image and clear image after decryption are good values for a statistical test. MSE is equal to zero and PSNR infinity number because no loss data or difference in this approach was found.
