Securities Exchange Board of India (Sebi) chairman Tuhin Kanta Pandey has warned of potential cybersecurity risks posed by advancements in quantum computing, likening it to the Y2K crisis. Unlike the Y2K bug, which had a clear deadline, the quantum threat lacks a definitive timeline, raising concerns about inaction and data vulnerability. Sebi is proactively developing a roadmap to implement post-quantum cryptography by 2028-29, while the government has allocated significant resources for quantum research under the National Quantum Mission. Experts emphasize the urgency for a comprehensive national strategy to safeguard sensitive data and ensure a smooth transition to quantum-safe systems, highlighting that proactive measures are crucial to avoid future crises.
