IntegraQOS — PQC-Secured Immutable IoT OS

A hardened, crypto-agile operating system architecture for IoT and edge devices that combines immutable system state, trusted boot, signed lifecycle management and post-quantum-ready device trust.

Business context

What this capability solves

IoT fleets often remain deployed for years, run heterogeneous firmware, receive inconsistent updates and depend on long-lived cryptographic identities. IntegraQOS is designed to reduce persistence and tampering risk while making device identity, communications and update trust ready for a staged PQC transition.

EBP Integra delivery principle

Technology is implemented as an operating capability: architecture, integration, governance, assurance, people, procedures and measurable outcomes are designed together.

Deep-dive capabilities

Capability model

Modular building blocks allow the scope to start with a focused pilot and expand into an enterprise operating model.

Immutable Base System

Read-only or image-based system partitions minimize persistent modification and configuration drift.

Trusted Boot Chain

Secure/measured boot, hardware-backed roots of trust and integrity measurement establish known-good device state.

PQC-Ready Device Identity

Crypto-agile device certificates, hybrid key establishment and rotation policies support staged quantum-safe transition.

Signed OTA Lifecycle

Cryptographically signed A/B updates, staged rollout, rollback controls and fleet health validation.

Application Isolation

Least-privilege workloads, container/sandbox isolation, restricted services and minimized attack surface.

Remote Attestation

Expose device integrity evidence, software identity and policy posture to fleet or zero-trust access decisions.

SBOM + CBOM

Track software components and cryptographic dependencies per image/device generation.

Fleet Policy & Telemetry

Central policy, secure configuration, event telemetry, vulnerability posture and remediation status.

Reference architecture

How the capability fits together

Final topology, control placement and deployment model are validated during discovery and detailed design.

Hardware Trust

TPM/secure element/TEE where available, boot measurements and device-bound identity.

Immutable OS

Minimal read-only base, controlled writable state, application isolation and hardened service profile.

Crypto & Network

Hybrid/PQC-ready identity, secure transport profiles, key rotation and zero-trust device access.

Fleet Control Plane

Image signing, OTA orchestration, attestation, SBOM/CBOM, policy, telemetry and device lifecycle evidence.

Implementation

Phased delivery

Each phase ends with evidence, acceptance criteria and a decision gate before broader scale-out.

1. ProfileSelect hardware class, lifecycle, threat model and connectivity constraints.

2. HardenBuild immutable OS image, trust chain and isolation profile.

3. Quantum-readyIntroduce crypto-agile/hybrid device identity and secure transport.

4. OperateSign, attest, update, monitor and govern the fleet throughout its lifecycle.

IntegraQOS is a proposed EBP Integra solution concept. Algorithm profiles, supported hardware, certification targets and safety requirements must be validated for each device class and deployment environment.
