Hardware-accelerated AES-GCM encryption and mutual authentication for safety-critical robotic communication topics.
Conforming to the OMG DDS Security specification, every node possesses an X.509 certificate. Governance XML files strictly specify which cryptographic keys can publish or subscribe to sensitive topics like `/emergency_stop`.
By offloading payload encryption to CPU AES-NI instructions, telemetry packets are authenticated and encrypted on the wire in under 1.5 microseconds, preventing packet injection or man-in-the-middle attacks.
