Trusted Platform Module
A hardware root of trust that holds keys, measures boot and signs attestation evidence.

QualificationDevices and releases tested against the protocol, state on record.
Qualification, inside Protocol & Grid: trusted Platform Module, DICE layered identity, secure device identifiers, remote attestation architecture and more. Every item is traced to its specification, from TCG TPM 2.0 Library Specification to ISO/IEC 11889, and runs on the open Observatory Protocol.

01What it is
Device identity and attestation.
How every node proves what it is and what it runs, how links and keys are protected, how software is traced to its source, how personal data is minimised, and how incidents are found and handled. Each technology below carries what it is, what we do with it, and the standard it is drawn against.
Security, identity and trust
DICE layered identity
Device identity derived from each firmware layer for microcontrollers without a TPM.
We design and integrate.
TCG DICE Layering Architecture
Security, identity and trust
Secure device identifiers
Factory-installed and locally significant device identities bound to hardware.
We design and integrate.
IEEE 802.1AR-2018 (IDevID, LDevID)
Security, identity and trust
Remote attestation architecture
Roles of attester, verifier and relying party, so trust in a node is evidence-based.
We design, integrate and operate.

Entity Attestation Tokens
Signed claims about a device’s state carried as CWT or JWT.

Secure elements
Tamper-resistant chips that store credentials on constrained devices.
We design and integrate.
