This isn't just about Airtel but for every organisation as MAVLink has supported per-message signing since MAVLink 2, yet almost no real-world PX4 fleet enables it, because key distribution, rotation & revocation across dozens of airborne vehicles has no production-ready tooling, so most swarms still accept any correctly formatted command from whatever radio reaches them. A single spoofed ground station or one drone with cloned key can inject commands rest of swarm has no way to reject. Talk introduces swarm-native trust layer that issues short-lived, mission-scoped MAVLink signing keys from a lightweight onboard authority, lets every drone verify signatures independently without round-tripping to a ground station & adds a peer-consensus exclusion protocol so that if one drone starts broadcasting commands inconsistent with its own attested mission profile, the rest of swarm votes to ignore it mid-flight without operator intervention. We demonstrate this on PX4 SITL & real hardware over a Zenoh-based inter-drone link, show a live command-injection attack being rejected by consensus & discuss key rotation strategy under degraded or fully lost ground-station connectivity mid-mission.
