As we envision the future of 6G, the sheer complexity of the network – connecting billions of devices, from smart city sensors to autonomous vehicles, makes manual management of networks impossible.
To address this complexity, researchers and network engineers introduced a revolutionary concept called Intent-Based Networking (IBN). Instead of engineers writing thousands of lines specifying how to configure the network devices, they simply provide a high-level “intent,” such as “ensure low latency for all emergency vehicles in this sector”. The network’s “brain” and “intelligence, then automatically figures out how to make that happen.
But what if someone tries to trick or attack this system? This is the core challenge addressed by Proof of Concept 5 (PoC#5).
The Vulnerability: When the Network is Misled
An IBN relies on a constant stream of data, known as telemetry, to understand its current state. It looks at metrics like CPU usage, link data-rate and usage, latency and connection quality to decide if it is meeting the user’s needs and intent.
The danger lies in data tampering. If an attacker can secretly alter these telemetry streams, they can feed the IBN system false information. For example, by making the network believe a certain path is congested when it is not, an attacker could force the system to redirect sensitive traffic through a compromised server. Because the network thinks it is following the right intent, this “poisoning” of the system’s knowledge base can be incredibly difficult to spot. It’s the digital equivalent of changing the road signs to force a self-driving car into a trap.
How PoC#5 Guards the Network’s Intent
- Knowledge Base Integrity: The PoC will also seek to protect the IBN knowledge base, protecting the system from potential internal threats which could cause disruption to network operations when erroneous intents – altered by an adversary, are applied in a network
- Authenticity Validation: The system will verify that telemetry data is coming from a legitimate, authorized source.
- Anomaly Detection for Telemetry: Using advanced AI, the system will monitor the telemetry streams themselves. If the data being reported doesn’t match the physical reality of the hardware, or is found to be anomalous, it will flag this as a potential tampering attempt.
The Impact: A Network which can be Managed with Confidence
This work is essential for the trustworthiness of 6G. As we move toward a world where critical infrastructure are managed by automated systems, we must be certain that the “intent” of human operators cannot be hijacked by malicious actors.
Through PoC#5, MARE is ensuring that the intelligence of 6G remains a tool for progress, protected against the threats of the digital age.
