Service / PQC & Quantum Migration

HNDL / TNFL Risk Assessment

Prioritize post-quantum migration using confidentiality lifetime, threat horizon and time needed to change complex systems.

Business context

What this capability solves

Quantum risk is not only a future-event question. Data stolen today may remain valuable later, while migration can take years. Prioritization must combine data life, exposure and change difficulty.

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.

Data Lifetime

Estimate confidentiality/validity period of protected information and signatures.

Threat Horizon

Use scenario ranges rather than a single speculative Q-Day date.

Migration Lead Time

Estimate vendor, architecture, testing, procurement and rollout complexity.

Exposure Path

Assess harvest-now-decrypt-later and trust-now-forge-later scenarios.

Criticality

Factor business, safety, regulatory and national/strategic importance.

Priority Model

Rank assets into migration waves with transparent assumptions and owners.

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

Approved cryptographic profile registry
Hybrid-first transition where compatibility requires it
No untested algorithm replacement in production
Key/certificate lifecycle and fallback controls
Vendor and firmware dependency tracking
Independent test evidence for critical systems
Exception ownership and retirement dates

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.
