Robot Authentication

Robot Authentication
Verification of the identity of a robotic component or system

Robot authentication refers to verifying the claimed identity of a robot or one of its communications participants before a protected operation. The entity being verified might be the robot hardware, an onboard controller, a middleware process, an operator, or a remote service. Authentication is not the same as safety validation or permission to execute arbitrary commands.

Common approaches

Approaches include device certificates, mutual TLS, signed messages, protected keys, and hardware-based credentials. Identity and communication design depend on the threat model: a robot connected to a factory control network faces different risks from a household research platform.

Middleware example

ROS 2 has security capabilities that depend on compatible middleware and configuration. The ROS 2 security model describes participant credentials, encrypted communication, and permission policies; using ROS 2 does not automatically mean these protections are configured.

Operational limitations

Authentication can limit impersonation but cannot alone protect against faulty sensors, compromised authenticated devices, maliciously authorized users, or unsafe motion. Systems require additional safety controls, updates, monitoring and incident response.
