EAT -- EAT - Entity Attestation Token

 

About EAT
English (USA)

Entity Attestation Token (EAT) is proposed as a general purpose signed
attestation token to prove provenance and characteristics about an end
client device, node or entity to a server or service. The proposal uses
CBOR to represent claims to be small, compact and general purpose,
particularly for very small IoT devices. COSE is used so the
cryptography and signing is up to date.

EAT is not tied to any particular use case. It is intended as a
general mechanism for any use case where a server or service requires
proof of device provenance, configuration and characteristics. These use
cases might include IoT device claiming and on boarding, online banking
and payments, biometric authentication, DRM/content protection and
authentication risk engine inputs.

EAT is intended to be flexible with regard to the devices signing key
material so as to accommodate many device manufacturing scenarios. For
example, the proposal can use IEEE Device ID, ECDAA or even symmetric
key material.
