The client is one of Asia Pacific’s largest private sector banks by assets and market capitalisation. The bank operates a distribution network of various branches across many cities and villages in India, with a strong international presence, serving millions of customers across retail, corporate, and institutional segments.
Key Facts
Vulnerable Sector: The Banking & Financial Services sector is among the most susceptible to quantum computing threats.
Approaching Quantum Threat: 57.5 % expect a significant quantum threat within three years. Source: TOI
Sustainable Security: Banks must adopt long-term cryptographic resilience without disrupting mission-critical services.
NIST Compliance: Preparing for global PQC standards set by NIST and anticipated Indian regulatory guidelines.
Increasing global adoption: Nearly 80% of the world’s 50 largest banks are now actively engaging with quantum technologies, moving toward strategic investment in quantum-safe systems. Source: Techinformed
Challenges Faced: Securing mobile & server applications against quantum threats
Why was this a problem?
Outdated Encryption: RSA and ECC, long-standing encryption standards, are vulnerable to being broken by quantum algorithms like Shor’s, which could render digital signatures and customer data easily decryptable.
Time is ticking: With the “harvest now, decrypt later” attack model, data captured today can be compromised tomorrow.
Regulatory Compliance: With global and Indian regulators moving toward mandating PQC standards, early action is essential to remain compliant and competitive.
After a detailed assessment, QNu Labs deployed its QShieldTM SDK and Quantum Random Number Generator (QRNG) to future-proof the bank’s digital channels.
Phased PQC Migration: Gradual migration from RSA/ECC to PQC-based algorithms minimises risk and enables controlled testing.
QShieldTM SDK Integration: Embedded directly into mobile applications and server-side components, enabling quantum-safe digital signatures and secure key exchange operations.
Quantum-Grade Entropy: Integrated QNu’s Tropos QRNG via SDK to inject true quantum entropy into all cryptographic processes, ensuring unpredictability and resilience in key generation and cryptographic operations.
QNu’s Differentiators
Seamless Integration: Minimal to no disruption to the existing banking infrastructure.
Regulatory Alignment: Ahead of NIST PQC mandates and upcoming Indian security regulations.
Born in India, Built for the World: Indigenously designed, developed & manufactured (IDDM) systems.
Scalability: Solutions are scalable to address customer-specific needs.
Results Achieved
It is one of the first-of-its-kind PQC deployments in India’s BFSI sector, enabling the client to safeguard against Q-Day risks while proactively enhancing customer trust. With QNu’s quantum-resilient framework in place, the client is setting a benchmark for APAC BFSIs’ journey into the quantum era.
100% PQC Compliance: Aligned with NIST-Approved Algorithms
Future-Ready Applications: Mobile and server apps secured with PQC.
Scalable Architecture: PQC framework extended across other banking applications.
Enhanced Customer Trust: Reinforces its position as a technology-driven, future-ready financial leader.
