Intent-Based In-flight Service Encryption in Multi-Layer Transport Networks

This work addresses secure service provisioning in multi-layer transport networks for network operators, but it appears incremental as it builds on existing SDN and intent-based frameworks.

The paper tackled the problem of providing encrypted services across multiple network layers by introducing the ACINO orchestrator, which integrates a novel intent interface with an ONOS-based SDN orchestrator to enable encryption at IP, Ethernet, and optical layers.
