A national report on quantum cryptography could have been a survey of physics. This one is a programme-management document. Its central contribution is not explaining the threat — it is assigning dates, owners, and an order of operations. For anyone in Indian BFSI, those three things are the whole story.
Three milestones, two timetables
The report defines a three-stage migration and then runs it on two clocks depending on who you are.
- Milestone 1 — Build the Foundations. Establish governance, complete discovery and inventory of cryptographic assets, run quantum risk analysis, adopt crypto-agility as a guiding principle, and begin requesting and then mandating CBOMs from vendors. CII: by 31 Dec 2027. Regular enterprises: by 31 Dec 2028.
- Milestone 2 — Migrate High-Priority Systems. Convert pilots into funded programmes, enforce a strict "no new classical-only deployments" policy, deploy PQC-capable PKI and hybrid certificates, and upgrade HSMs, KMS and libraries. CII: by 31 Dec 2028. Regular: by 31 Dec 2030.
- Milestone 3 — Full PQC Adoption. PQC becomes the default across all systems, classical-only trust chains are retired, and crypto-agility is institutionalised as ongoing practice. CII: by 31 Dec 2029. Regular: by 31 Dec 2033.
The compression for CII is deliberate. Critical Information Infrastructure — power, telecom, defence, and the financial-market plumbing that supports them — must finish in 2029 what other enterprises have until 2033 to complete.
The personas: the report's prioritisation logic
Rather than treating all organisations identically, the report sorts them into PQC Personas based on quantum-risk exposure, system longevity, and data sensitivity:
- Urgent Adopters — critical infrastructure and high-risk operators (the report names Power, Telecom, ISRO, DRDO, ONGC). Accelerated timelines across every milestone.
- Regular Adopters — moderate-risk enterprises following the baseline 2028 / 2030 / 2033 schedule.
- Technology Providers & Enablers — vendors of cryptography-related products, expected to lead by example and support the broader ecosystem.
The crucial subtlety: an organisation can match more than one persona, and the highest-risk persona governs. A bank that also operates payment-switch infrastructure with long-lived keys does not get to claim the comfortable timeline. This single rule pulls a large slice of BFSI toward the urgent end of the spectrum.
The migration is not a technology upgrade. The report calls it a fundamental shift in digital trust — governed, funded, and audited like one.
CBOM as the universal gate
One instrument threads through every milestone: the Cryptographic Bill of Materials. From FY 2026–27 organisations are told to begin requesting CBOMs and quantum-resiliency roadmaps from vendors in procurement; from FY 2027–28 they must mandate CBOM submission through procurement policy. This is the lever that propagates the entire programme through the supply chain — a bank cannot meet its obligations if its core-banking, payments and HSM vendors cannot produce a credible cryptographic inventory.
Assume-breach, and no new classical-only systems
Two principles in the report deserve to be quoted into every internal strategy deck. The first is assume-breach: plan as though HNDL adversaries are already capturing your traffic, because retrospective mitigation after Q-Day is impossible. The second arrives at Milestone 2 — a strict "no new classical-only deployments" policy. Read carefully, that obligation bites well before 2028: every procurement and architecture decision made now either adds to the migration backlog or doesn't. The cheapest quantum-safe migration is the classical system you never deploy in the first place.
What a bank should take from the document
Three things. First, find your row and your persona — and apply the highest-risk one honestly. Second, treat 2027 (not 2030) as the live deadline, because the foundation work is where the years go. Third, recognise that CBOM is the load-bearing deliverable: without an accurate cryptographic inventory, risk analysis, prioritisation, roadmap and vendor governance all rest on guesswork.
The report's Milestone 1 is, almost line for line, what KavachQ's SCORE and PLAN modules produce: a CycloneDX 1.6 CBOM, a quantum risk classification, a DST persona classification, and a prioritised migration backlog with effort estimates mapped to the 2027/2028/2029 deadlines. It is purpose-built around this report's structure rather than retrofitted to it. → See N° 03 for what a CBOM contains, and N° 06 for the phased plan.
