Service / PQC & Quantum Migration

IoT / OT PQC Migration

Plan quantum-safe transition for constrained, safety-sensitive and long-lived device environments without disrupting operations.

Business context

What this capability solves

IoT/OT systems can remain deployed for a decade or more, often with fixed cryptography and vendor-controlled firmware. Migration requires hardware, performance, safety and fleet lifecycle considerations.

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.

Device Segmentation

Group hardware classes by CPU/memory, lifecycle, connectivity and criticality.

Firmware / Crypto Inventory

Libraries, boot/signing, device identity, transport and update cryptography.

Hardware Readiness

Assess secure elements, TPM/TEE, memory/CPU and upgrade constraints.

Hybrid Device Trust

Pilot PQC-ready identity and key establishment with safe fallback.

OTA / Signing

Modernize update signing, A/B deployment and anti-rollback.

Fleet Governance

Track supported profiles, exceptions, patch state and replacement requirements.

Reference architecture

How the capability fits together

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

Inventory & Evidence

Assets, algorithms, protocols, keys, certificates, libraries, firmware, owners and dependency graph.

Risk & Governance

Data lifetime, HNDL/TNFL exposure, criticality, migration difficulty, target profiles and exception authority.

Migration Engineering

Hybrid algorithms, PKI/HSM/KMS, protocols, applications, devices, interoperability and test environments.

Continuous Crypto-Agility

Rescans, posture dashboard, key rotation, retirement, vendor tracking, evidence and assurance.

Controls & governance

Implementation

Phased delivery

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

1. DiscoverEstablish authoritative crypto inventory and ownership.

2. PrioritizeRisk-rank exposure using data lifetime, criticality and migration effort.

3. PilotValidate target/hybrid profiles and interoperability in controlled environments.

4. MigrateExecute waves, rekey, retire legacy, rescan and maintain evidence.
