End-to-End Encryption in Optical Transport Networks

With the increasing demand for secure high-capacity communications, OTN encryption has emerged as a powerful solution for protecting data beyond the traditional ITU-T OTN G.709 framework in metro and core networks. By encrypting the OTN transport payload frame (OPUk), operators gain a protocol-agnostic and highly efficient security mechanism.

✅ OTN Encryption: Provides end-to-end encryption across all client types and protocols without additional overhead, ensuring 100% capacity utilization and minimal delay.
✅ Ethernet Encryption (MACsec): A trusted security mechanism for high-speed metro access networks, securing data transfer at Layer 2 with strict security compliance.
✅ IPSec Encryption: A widely used protocol for securing Layer 3 (IP-based) communications, ideal for establishing secure tunnels between network sites.
✅ Application Layer Encryption (TLS): Protects Layer 4-7 client-server sessions, ensuring privacy and integrity for web, cloud, and enterprise applications.

As part of the ALLEGRO project , we are driving next-generation encryption solutions to enhance security across optical networks. By leveraging multi-layer encryption strategies, we enable a future of fast, secure, and efficient communications.

Let’s innovate and shape the future of optical network security together! 🚀
