摘要

提出了一种基于储层DNA和索引置乱的相干光正交频分复用系统物理层加密方案，该方案利用高维超混沌产生的密钥序列进行加密。在16QAM CO-OFDM系统中，通过50 km标准单模光纤传输，以40 Gsps的符号速率对该方案进行了仿真。结果和分析表明，该方案可以在$\sim 10^{225}$的密钥空间下提高系统的安全性，保证加密性能在可以忽略不计的代价内。

Physical Layer Encryption Scheme based on Reservoir DNA and Index Scrambling in the CO-OFDM system

In this paper, a physical layer encryption scheme is proposed in coherent optical orthogonal frequency division multiplexing system based on reservoir DNA and index scrambling using key sequences generated by higher-dimensional hyper-chaos. Simulations of the proposed scheme are conducted in a 16QAM CO-OFDM system via 50 km standard single mode fiber transmission at the symbol rate of 40 Gsps. Results and analyses show that the scheme can enhance the security of system with a key space of $\sim 10^{225}$, which guarantees encryption performance within a negligible penalty.
