Abstract: Embodiments of the present disclosure describe a secure, scalable and extensible aircraft and other system and device identity management (IdM) system that enables services for identity provisioning (idP), and identity validation, verification and authentication (idVV&A). The identity and management system uses dual-mode local broadcast and network connected device communication elements across a wide area network. The system serves as a Source System of Record (SSoR) that securely ingests private registration data, system/device identity verification and authentication requests and returns validated identity and activity information.
