eMudhra warned that the transition to post-quantum cryptography could represent a Y2K-scale disruption for global digital infrastructure, raising questions for enterprises, governments and infrastructure operators about preparedness. The company noted that advances in quantum computing threaten to break widely used encryption standards and that sensitive information encrypted today could be harvested and decrypted in future as quantum capabilities mature. It observed that regulators in the United States and Europe have begun pushing organisations towards quantum-resistant cryptography to protect long-term data and critical infrastructure. eMudhra said the shift may require large-scale changes across enterprise infrastructure, identity systems and digital public infrastructure comparable in complexity to the global remediation efforts undertaken during the Y2K transition. The company indicated that legacy certificate lifecycles, authentication systems and secure communications may need overhaul, and that long-term data protection strategies should be reassessed to mitigate future risk. It urged organisations to commence inventories of cryptographic assets and to prioritise migration planning. The firm warned that boards and security leaders must treat post-quantum readiness as a strategic priority as organisations expand cloud adoption, digital services and autonomous systems. The transition is likely to have broad implications for digital identity, financial systems and global trust infrastructure, affecting how trust anchors and certificate authorities operate at scale. Security teams will need to update trust architectures, test interoperability of quantum-resistant algorithms and coordinate with partners and regulators to preserve operational continuity. As quantum research accelerates, the company said proactive planning and modernisation of trust infrastructure will be essential to sustain resilience and confidence in the digital economy. eMudhra, which provides digital identity, authentication and trust services with capabilities in public key infrastructure and certificate lifecycle management, noted that organisations should engage vendors and update procurement specifications to include quantum-resistant solutions. Establishing verifiable trust across users, devices and services will underpin secure digital transformation.
