Service / PQC & Quantum Migration

Hybrid PQC Migration

Introduce quantum-safe primitives alongside classical cryptography while preserving interoperability and operational confidence.

Business context

What this capability solves

Immediate classical-only retirement may be impractical. Hybrid migration allows organizations to gain PQC protection while retaining established classical assurances during 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.

Hybrid Key Establishment

Combine classical and PQC key establishment according to approved platform capabilities.

Hybrid Authentication / Signatures

Evaluate dual-signature or transition trust patterns where appropriate.

Compatibility Testing

Test clients, servers, proxies, libraries, HSMs and network middleboxes.

Performance Engineering

Measure handshake size, CPU, memory, latency and constrained-device impact.

Fallback Governance

Define when fallback is allowed, detected, logged and retired.

Wave Migration

Pilot, expand, rekey and remove classical-only paths based on risk.

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.

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.
