  • Industry Contribution: The banking and financial sector contributes the highest volume of transactions, followed by e-commerce, telecom, and government payments.
  • Compliance Standards Met: The organization adheres to NIST-approved Post-Quantum Cryptography (PQC) standards, ensuring future-proof security against quantum threats.

The Challenge: Securing a Nation’s Financial Backbone

As digital payments ecosystem continues to expand, the organization faces increasing threats from Quantum Computing and AI-driven attacks, necessitating future-proof security solutions.

Why This Is a Problem

  1. Public Trust in Digital Payments – Ensuring confidence in secure transactions.
  2. Quantum Computing Threats – Future quantum computers could break existing encryption.
  3. AI Predicting RNG Patterns – Advanced AI models can compromise randomness in cryptographic systems.
  4. Future Compliance Needs – Regulatory bodies will mandate quantum-resistant security.
  5. Increasingly Sophisticated Attacks – Cyber threats are evolving rapidly.
  6. Expanding Attack Surface – Hundreds of interconnected apps create multiple vulnerabilities.

Why This Was Not Addressed Earlier

  • Scale & Complexity – National infrastructure is vast and intricate.
  • Perceived High Cost – Quantum implementations were seen as expensive.
  • Fear of Disruption – Concerns about interfering with critical operations.
  • Integration Challenges – Merging new security technologies with legacy systems.
  • Unclear Transition Path – Lack of structured migration strategies.
  • Compliance Uncertainty – Future regulations were unpredictable.
  • Long Transition Timelines – Change management requires significant effort.
