Secure DNA-Coding Image Optical Communication Using Non-Degenerate Hyperchaos and Dynamic Secret-Key

With the aim of tackling insufficient security in chaotic encryption algorithm for digital images Optical Access Network, a color image scheme combining non-degenerate discrete hyperchaotic system and deoxyribonucleic acid (DNA) dynamic encoding is proposed. First, new constructed with all positive Lyapunov more complex characteristics. Furthermore, key sequence based on generated using plaintext correlation to achieve effect secret key. Next, binary bit-planes permutation performed one sequences. Then, used sequentially perform DNA encoding, obfuscation, decoding. Finally, obfuscation obtain final ciphertext. The research results show that can pass NIST 800-22 test, corresponding resist various common attacks has strong anti-interference ability. In addition, verified ARM-Embedded, which proves proposed this paper feasible secure communication technology scheme. Therefore, helpful provide ideas design application high-security cryptosystem optical access network.
