Abstract
The evolution journey of optical network (ON) towards heterogeneous and flexible frameworks with high order of applications is continued from the last decade. Furthermore, the prominence of optical security, amount of transmitted data, bandwidth, and dependable presentation are heightened. The performance of ON is degraded in view of various natures of attacks at the physical layer, such as service disrupting and access to carrier data. In order to deal with such security breaches, new and efficient ON must be identified. So, this paper elaborates a detailed structure on physical layer security for heterogeneous ON. Possible mechanisms, such as Elliptic-curve Diffie–Hellman (ECDH), are used to treat a physical layer attack, and an efficient framework is proposed in this paper for 64 quadrature amplitude modulation-based orthogonal frequency division multiplex (64QAM-OFDM) ONs. Finally, theoretical and simulation validations are presented, and the effective results of the proposed method and viewpoint are concluded.
Highlights

Secure and long range consistent communication framework is set to become a crucial demand in the near future
Summary
The expanding request of client work for bigger transfer speed has introduced the development of heterogeneous optical networks (ONs) [1] Such a framework adjusts to broaden high throughput, portability, and future information interconnects. Seeing that presently data stream of the ONs surpass 100 Gbps, continuous executing, low-latency signal handling for data security has been progressively tested [6] To treat such challenges, the parallelism and better speed of optical signal processing is considered a good option for continuously handling such signals in real time and the physical layer of the ONs. Adding to the previous discussion, the security of the encryption previously gave in the higher layer of protocol stack is enhanced in the optical layer [7]. In contrast to their digital parameters, the electromagnetic waves are not induced in optical domains; in results, less external interactions happen to the ONs
