PQC Migration and Algorithm Selection23 Jun 2026

Key Encapsulation Mechanisms Explained for Security Architects

Most post-quantum cryptography literature describes ML-KEM as "the NIST post-quantum key exchange." That framing is close enough for a headline, and wrong enough to cause real implementation errors. ML-KEM is not a key exchange protocol in the sense that ECDH is. It is a key encapsulation mechanism, a formal cryptographic primitive with a different API, a different security model, and different composition properties.

Post-Quantum TLS: What Changes and What Stays the Same

Post-quantum TLS migration changes two things: the key exchange algorithm and, eventually, the certificate signature algorithm. The record layer, the handshake state machine, session resumption, and OCSP stapling are structurally unchanged. An engineer who understands what is not changing is in a much better position to sequence the migration.

CNSA 2.0 for Defence Contractors: Which Obligations Apply to Your Programmes

The common problem in defence contractor CNSA 2.0 planning is not a lack of awareness that the requirement exists. It is the gap between knowing it exists and knowing which specific programmes it applies to, which milestones are immediately operative, and how CNSA 2.0 interacts with CMMC certification.

The Data Lifetime Problem: When Encryption Decisions Outlast the Threat Model

Every encryption decision is made against the threat model that exists at that moment. The data it protects may need to remain confidential for a decade beyond that point. This article applies the Mosca inequality to classify existing encryption decisions as immediate, deferred, or irreversible, with worked examples across NHS records, ICS firmware, and enterprise email archives.

CNSA 2.0 vs CNSA 1.0 for Quantum Key Management: What Is Changing in 2026 and 2027

The 2026 KMS deadline in NSA's CNSA 2.0 roadmap requires all new key management and PKI systems to support ML-KEM-1024 and ML-DSA-87 natively. This article covers the KMIP 2.2 requirement, FIPS 140-3 HSM certification timelines, and the key wrapping vulnerabilities that remain quantum-exposed even after the algorithm swap.

Quantum Security Governance: Building a Board-Level Framework

Quantum risk briefings are now common at board level. Governance is not. This article sets out a five-element framework using NIST CSF 2.0 as the governance architecture, covering named accountability, CBOM as the Map deliverable, board-level metrics, escalation protocols, and regulatory obligations under NIS2, ISO 27001, and SEC 17 CFR 229.106.

HNDL in Financial Services: Regulatory and Operational Implications

Financial services institutions hold the data categories with the longest regulatory retention periods, are documented targets of nation-state cyber operations, and already operate under ICT risk management frameworks carrying technology-currency obligations on cryptography. The interaction of these three factors means HNDL is not a future consideration for this sector.

How to Calculate Your Organisation's HNDL Exposure

Harvest-now-decrypt-later exposure is calculable, not qualitative. An organisation that knows its network topology, data retention requirements, and current key exchange algorithms can produce a scored HNDL exposure assessment for any system in its estate. This article explains the I x L x A calculation methodology, works through three concrete examples, and shows how the score drives migration priority sequencing.

NCSC PQC Migration Guidance: The UK Position Explained

On 20 March 2025 the NCSC published its first dedicated PQC migration timeline, setting milestones at 2028, 2031, and 2035. For operators of essential services under the UK NIS Regulations 2018, those dates define the technical baseline competent authorities will use. This article explains what each phase requires, how it connects to UK legal obligations, and why 2028 is the milestone that demands attention now.
