PQC & Quantum Migration • PQ-09
IoT / OT PQC Migration
The hardest estate: constrained devices with long lives and no easy update path.
Scope
What the engagement covers.
Industrial and connected devices often cannot accept larger keys, lack update mechanisms, or sit in processes that cannot be interrupted. This service plans migration around those constraints, including the option of a post-quantum secure device operating system where replacement is warranted.
Included capabilities
- Device population analysis by cryptographic and compute capability
- Constrained-device algorithm selection and lightweight profiles
- Firmware update and secure boot chain migration
- Device identity, provisioning and certificate lifecycle at fleet scale
- IntegraQOS evaluation where an immutable, PQC-ready device OS is the better path
Outputs and deliverables
- Device population and capability analysis
- Segmented migration strategy per device class
- Secure boot and update chain design
- Field trial results and fleet rollout plan
Workflow
How it is delivered, step by step.
Each step has an owner, an entry condition and an artefact that has to exist before the next step begins.
01ProfileDevice classes, compute headroom, update capability and lifespan.
02SegmentSplit into upgradeable, replaceable and compensating-control groups.
03DesignAlgorithm profiles, identity model and update chain per segment.
04Field trialControlled deployment on a representative device population.
05Roll outStaged fleet migration with process-window and safety coordination.
Use cases
Where this is typically applied.
Manufacturing controllers inside certified safety processes
Connected medical or transport devices with long certification cycles
Delivery model
The operating pattern for PQC & Quantum Migration.
The same delivery discipline applies across every capability in this line, so combined engagements stay coherent.
Discover
Find every certificate, key, library, protocol and hardware dependency.
Prioritize
Rank by harvest-now-decrypt-later exposure, data life and migration effort.
Design
Hybrid profiles, agility interfaces, PKI and key lifecycle target state.
Migrate
Waves, pilots, fallback paths, exception handling and change control.
Operate
Posture monitoring, algorithm governance, revalidation and reporting.
Integration
- Certificate lifecycle management and PKI platforms already in place.
- HSM estate, key management services and cloud KMS.
- CI/CD pipelines, so crypto inventory stays current as code ships.
- Asset and configuration management for device and endpoint coverage.
Engagement approach
Most clients begin with discovery and risk mapping as a contained first phase, because nothing else can be planned credibly without an inventory. Migration then runs in waves aligned to certificate renewal and platform refresh cycles rather than as a separate programme.
