India's Quantum-Safe Playbook: 128 Pages Distilled into One Actionable Brief

India just codified the most aggressive post-quantum cryptography migration timetable outside the Western bloc. CII must reach full PQC adoption by 31 December 2029. CBOM becomes a procurement mandate from FY 2027–28. Every vendor selling into Indian government or CII must be ready by April 2027.

What This Report Covers

A forensic condensation of the 128-page National Quantum Mission Task Force report  chaired by Dr Rajkumar Upadhyay, CEO, C-DOT  built for CISOs, procurement leads, and compliance officers. Every deadline, assurance level, migration milestone, and testing requirement, with original page references for cross-checking.

Prepared by QNu Labs in association with SITG Consulting.

Why This Matters Now

Binding Deadlines — Closer Than You Think

India's CII timetable is more aggressive than the UK, Canada, and the EU (all 2035). Only Australia's RSA and ECC cessation (end 2030) comes close.

• 31 Dec 2027 — CII foundations: governance, cryptographic inventory, risk assessment, CBOM procurement clauses. ‍
• 31 Dec 2028 — High-priority migration. No new classical-only deployments. PKI, HSM, KMS upgrades mandatory.
• ‍31 Dec 2029 — Full PQC adoption. PQC-only trust chains. All digital signatures quantum safe.

Regular enterprises: 2028, 2030, 2033.

Assume-Breach Is Now Official Policy

The report adopts an assume-breach posture against Harvest Now, Decrypt Later. Retrospective mitigation after Q-Day is infeasible. The CRQC window: 2028 to 2032 — tighter than NCSC's 2035 position.

CBOM: The New Procurement Gate

From FY 2027–28, every vendor selling into government or CII must submit a Cryptographic Bill of Materials — the parent of SBOM, HBOM (Hardware Bill of Materials), and QBOM (Quantum Bill of Materials).  

Not a recommendation. A gate with a fixed date.

Sovereign Certification Takes Shape

Four assurance levels (L1–L4). Three lab tiers (Tier-1 to Tier-3). Labs operational by December 2026. L4 — sovereign grade  requires indigenous cryptographic implementations, nation-state attack simulation, and Zero Trust compliance.

The report admits foreign OEMs will not share hardware documentation, making full hardware CMVP infeasible today. The sovereignty bottleneck, stated plainly.

What the Report Delivers

Global Regulatory Comparison

Nine jurisdictions in one table: US (RSA-2048 deprecated ~2030, USD 7.1B migration cost), EU (full migration by 2035), UK (high-priority by 2031), Australia (RSA/ECC cessation end 2030), Canada, Singapore, UAE, South Korea, China.

Six CII Migration Constraints

Latency sensitivity. Handshake frequency. User tolerance. Hardware limitations on legacy platforms. Vendor dependence. Cross-border standards dependencies. These are directly quotable in procurement conversations.

The Crypto-Agility Mandate

The report's sharpest line: Unlike most security controls, cryptography does not fail gradually; it fails definitively and absolutely. Crypto-agility reviews every 9–12 months become the stated cadence.

Where QKD and PQC Stand

PQC is the deployable default. QKD is strategic and sectoral. The hybrid architecture - PQC for breadth, QKD for depth aligns with NIST, NCSC, ACSC, BSI, and ANSSI.

QNu Labs operationalizes this through QShield™, integrating Armos (QKD), Tropos (QRNG), and Hodos (PQC) on a single sovereign platform.
