Non-interactive key agreement method between unmanned aerial vehicles under cloud network end architecture

Abstract

This invention discloses a non-interactive key negotiation method between drones under a cloud-network-edge architecture. The cloud server, acting as the control center for the drones, provides them with mission and flight path planning, significantly reducing their computational and storage burden. The cloud server also provides end-to-end authentication services, effectively ensuring the collaborative security of drone-like edge systems during tasks such as data sharing. In this invention, drones do not need to pre-store authentication materials for other drones, effectively reducing the storage pressure on sensitive data. The cloud server identifies drones requiring secure collaboration based on mission requirements and issues key negotiation authentication materials to these drones. The drones directly calculate their session keys with the collaborating drones based on the issued authentication materials. No direct message interaction is required between drones during the key negotiation phase, effectively avoiding problems such as lost or out-of-order authentication messages caused by unstable communication links between drones.
