Description of device-centric authentication (DCA) protocols and technology support (revised and extended)

The deliverable will describe DCA protocols, user/device and device/server interfaces and APIs, including description of needed extensions to FIDO standards with multi-level authentication and recovery mechanisms. Moreover, it will document how the trusted device execution environment can be exploited for human-to-device authentication, and it will document the implementation of TPM- and Telco-signed behavioral certificates.
