Quantum-Safe Cryptography Migration Gathers Pace Among Banks
JPMorgan, HSBC and DBS publish detailed transition roadmaps as NIST-standardised post-quantum algorithms move from theory to deployment.
JPMorgan Chase published a 42-page technical white paper this week outlining its enterprise-wide migration to post-quantum cryptographic standards, with full deployment targeted for 2030.
The bank disclosed that approximately 14,000 internal applications and 880 external integrations rely on cryptographic primitives that will require updating to NIST-standardised post-quantum algorithms — principally CRYSTALS-Kyber for key exchange and CRYSTALS-Dilithium for digital signatures.
HSBC and DBS published parallel roadmaps. The three institutions together represent the most concrete commitment yet from major global financial firms to address the so-called "harvest now, decrypt later" risk.
Quantum hardware capable of breaking current public-key cryptography remains years away by mainstream estimates. The migration nonetheless cannot wait, given the lifespan of long-dated financial contracts.
