A chaotic ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) encryption scheme is firstly proposed for security OFDM-WDM-PON in this paper. We adopt a dynamic key agreement based on the messenger RNA (mRNA) codebook to distribute the key, and the security and randomness of this key are enhanced by a pre-sharing key parameter set instead of transmission of a key directly. Also, the security key can be dynamically updated in real-time according to the needs of the users. The real (I) and imaginary (Q) parts of the QAM symbol matrix after modulation are encrypted by the correspondence between transfer RNA (tRNA) and amino acids and the selection mapping of DNA base complementary rules. Also, we add cubic permutation to ensure all data security encryption. The encrypted signals of 35.29 Gb/s on different wavelength channels are successfully demonstrated over a 25-km standard single-mode fiber (SSMF) and a back-to-back (BTB) system. It is proved that the proposed security OFDM-WDM-PON encryption scheme is compatible with the traditional WDM system, which can make full use of bandwidth resources and enhance the security with a large key space.

用于安全 OFDM-WDM-PON 和动态密钥协议的混沌 RNA 和 DNA

本文首次提出了一种用于安全OFDM-WDM-PON的混沌核糖核酸（RNA）和脱氧核糖核酸（DNA）加密方案。我们采用基于信使RNA（mRNA）码本的动态密钥协议来分发密钥，通过预先共享的密钥参数集而不是直接传输密钥来增强该密钥的安全性和随机性。此外，安全密钥可以根据用户的需要实时动态更新。调制后的QAM符号矩阵的实部（I）和虚部（Q）通过转移RNA（tRNA）与氨基酸的对应关系和DNA碱基互补规则的选择映射进行加密。此外，我们添加三次排列以确保所有数据安全加密。35的加密信号。在 25 公里标准单模光纤 (SSMF) 和背靠背 (BTB) 系统上成功演示了不同波长通道上的 29 Gb/s。证明所提出的安全OFDM-WDM-PON加密方案与传统WDM系统兼容，可以充分利用带宽资源，以较大的密钥空间增强安全性。
