Service / PQC & Quantum Migration

PKI Modernization

Prepare certificate authorities, trust chains, key management and certificate lifecycle for crypto-agility and PQC transition.

Business context

What this capability solves

PKI is a foundational dependency for identity, TLS, signing and devices. Migration requires careful coordination of CAs, HSMs, certificate profiles, relying parties and operational tooling.

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.

PKI Inventory

CAs, intermediates, trust stores, certificate profiles, issuance and relying parties.

Trust Architecture

Design transition chains, profile segmentation and validation behavior.

HSM / KMS Readiness

Assess algorithm support, firmware, key lifecycle and vendor roadmap.

Certificate Lifecycle

Enrollment, renewal, revocation, discovery and automated rotation.

PQC / Hybrid Profiles

Pilot supported certificate/signature approaches and compatibility.

Relying-Party Migration

Update applications, devices and trust stores in controlled waves.

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.
