Fiber wireless seamless integrated encryption transmission scheme based on ciphertext-key double collaborative DNA reconstruction
In this paper, a double reconstructive DNA encryption transmission scheme based on ciphertext-key coordination is proposed for a fiber wireless seamless integrated communication system. The scheme uses a 5D memristor ring chaotic system and 1D chaotic system to realize the double collaborative reconstruction encryption transmission of ciphertext-key information through DNA coding mapping rules. The key space of the chaotic system reaches 10<sup>221</sup>. This paper successfully demonstrated the transmission of 48 Gb/s encrypted 16QAM signals with 25 km standard single-mode fiber (SSMF) and 10 m wireless distance. The bit error rate (BER) of the signal can meet the hard decision forward error correction (HD-FEC) threshold @3.8 × 10<sup>-3</sup>. When the offsets of DNA masking factors are more than 1, the BER is greater than 0.4. The results show that this scheme can guarantee the security of the optical fiber wireless seamless integrated transmission system.
