RankShield Robotics is a verifiable, post-quantum security layer for robots and embodied AI. It authorizes every high-consequence action before the actuator moves, signs it with post-quantum cryptography, and writes a tamper-evident receipt to the RankShield Network — so an embodied agent can't act on a command it can't prove was authorized, and every action is one you can verify yourself.
Because in 2025 robots stopped being demos and started acting in factories, hospitals, and homes — and the first real attacks landed. A robot that acts on an unverified command can cause physical harm, and most robots today can't prove who authorized what they just did. RankShield Robotics puts a verifiable checkpoint between "the system decided" and "the robot moved."
Researchers showed a single shared cryptographic key could give anyone in Bluetooth range root on a humanoid robot — and the exploit could spread robot-to-robot, like a worm.
Per-device post-quantum identity means there is no shared key to steal, and an unauthorized command never reaches an actuator.
A crafted voice prompt convinced a humanoid to swing at a person and infect the robot standing beside it — the model was manipulated, so the body obeyed.
A pre-actuation policy gate authorizes or denies the resulting motion before the motor moves. Deny is the default; manipulation of the model can't bypass the gate.
After a physical-harm incident, the only record of what the robot was told to do is a log the attacker could quietly edit.
Every action is sealed to a tamper-evident transparency log, so the receipt of who authorized what is provable and independently checkable — not editable.
RankShield Robotics sits in front of the actuator. Each high-consequence command is checked against policy, signed with post-quantum cryptography, and recorded as a tamper-evident receipt before the robot moves. The result is a robot whose every meaningful action carries proof of who authorized it — proof you, an auditor, or an insurer can verify without trusting us. It builds on RankShield's live post-quantum and transparency stack; robot integration is in development.
A deny-by-default policy gate authorizes or denies each command before the actuator moves. The safe state is "no."
Per-device identity with composite ML-DSA and SLH-DSA (NIST FIPS 204/205). No shared keys — the UniPwn class of bug can't exist.
Every action sealed to an RFC 6962 transparency log. Anyone can check a receipt's inclusion proof — verify it yourself.
IETF RATS: the robot proves its running build and policy match a signed reference, or it is quarantined from the fleet.
Signed, multi-hop authorization across operator → fleet → robot. Revocable, replay-bound, no privilege escalation.
A post-quantum-signed revocation the gate honors fleet-wide — bounding the blast radius of a captured robot.
RankShield Robotics doesn't invent a private scheme. It anchors to the attestation, post-quantum, and transparency standards the industry is converging on — and produces the evidence the new robot-safety and machinery rules ask for.
A security brand built on verifiability has to be honest about its edges. RankShield Robotics authorizes the command path and proves what happened. It is not magic, and it is not a substitute for these:
RankShield Robotics is a new pillar of the RankShield Network. We're working with robot makers, fleet operators, and healthcare and defense teams on first deployments — pre-actuation authorization, post-quantum identity, and provenance you can audit. If autonomous machines act on your behalf, let's talk.
