--- title: "Qualification: Protocol & Grid | Nexus Observatory" description: "Qualification, inside Protocol & Grid: trusted Platform Module, DICE layered identity, secure device identifiers, remote attestation architecture and more." url: https://observatory.global/grid-services/qualification/ publisher: Nexus Observatory Inc. updated: 2026-10-27 --- [Nexus Observatory](https://observatory.global/) / [Protocol & Grid](https://observatory.global/grid-services/) / **Qualification** # Devices 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. [Plan with us](https://observatory.global/contact/) Architecture [The protocol](https://observatory.global/protocol/specification/) **Technologies**: 9 **At the frontier**: 1 **Protocol functions**: 5 of 8 **Industries served**: 6 Reference design, drawn to scale · drag to turn · hover a part **01** What 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 ### Trusted Platform Module A hardware root of trust that holds keys, measures boot and signs attestation evidence. We design and integrate. TCG TPM 2.0 Library Specification · ISO/IEC 11889 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. IETF RFC 9334 (RATS architecture) Security, identity and trust ### Entity Attestation Tokens Signed claims about a device's state carried as CWT or JWT. We design and integrate. IETF RFC 9711 (EAT) Security, identity and trust ### Secure elements Tamper-resistant chips that store credentials on constrained devices. We design and integrate. GlobalPlatform specifications **Frontier** · Security, identity and trust ### Physically unclonable functions Keys derived from silicon variation rather than stored, resisting extraction. We integrate. ISO/IEC 20897-1 (PUF security requirements) Security, identity and trust ### Zero-touch secure onboarding Devices proving their identity to the owner's network without shared secrets in the field. We design, integrate and operate. FIDO Device Onboard 1.1 · IETF RFC 8995 (BRSKI) Security, identity and trust ### Certificate profiles X.509 certificate and revocation list profiles used across devices and services. We design. IETF RFC 5280 **02** Architecture ## Where it sits, and what it speaks. Qualification draws on 1 domain and 8 layers of the spectrum; the highlighted layers carry this area. It speaks 5 of the protocol's 8 core functions. Device identity and attestation 8 PKI, secure boot and updates 7 Zero trust and network security 7 5G and wireless security 6 OT security and software supply chain 9 Privacy and data protection 7 Keys, cryptography and post-quantum migration 9 Monitoring, incident response and governance 8 01**Join** Identity, attestation quote, signed policy. 02**Admit** Admitted for a stated scope, nothing wider. 03**Describe** What, where, how and by whom, with calibration. 04**Time** One clock across the grid, with its error bound. 05**Observe** Every value with quality and provenance. 06**Qualify** Tested against the specification, state on record. 07**Federate** Signed exchange across grids and trust domains. 08**Orchestrate** Software and configuration by signed plan. **03** On the grid ## Every site joins one observing grid. The open networks on the grid today, over real relief and the geodesic cells we count them into. A site built here enrols into the same grid. **04** In the field ## Where this runs, sector by sector. 6 deployment scenarios from the sector research that rely on qualification.
