Roadmap announcement
India PQC Roadmap Strengthening Digital Security: The Department of Science and Technology (DST) has released a national roadmap for Post-Quantum Cryptography (PQC) migration in April 2026. The initiative aims to secure India’s digital infrastructure against future quantum threats.
It focuses on developing cryptographic systems that remain secure even when powerful quantum computers emerge. This step is crucial for ensuring long-term digital sovereignty and data protection.
Static GK fact: The Department of Science and Technology operates under the Ministry of Science and Technology, Government of India.
Why PQC is necessary
Advancements in Quantum Computing pose a serious threat to current encryption methods. Existing systems like RSA (Rivest–Shamir–Adleman) and Elliptic Curve Cryptography (ECC) are widely used in banking and communication.
Quantum computers can solve complex mathematical problems much faster than classical systems. This makes traditional encryption vulnerable to future attacks.
Static GK Tip: RSA encryption is based on the difficulty of prime factorization, a key concept in number theory.
Risks to cybersecurity
Quantum computing can lead to the breaking of existing encryption, exposing sensitive information. This includes financial data, emails, and government communications.
Another major concern is the “Harvest Now, Decrypt Later” strategy. Data encrypted today can be stored and decrypted once quantum systems become powerful enough.
There is also a systemic risk to sectors like power, telecom, and governance. A breakdown in cryptographic security could disrupt critical infrastructure.
National security concerns
The exposure of defence and intelligence data can weaken national security. It may also create strategic vulnerabilities in global geopolitics.
Securing encryption systems is therefore essential for safeguarding sensitive national information. PQC ensures resilience against such future threats.
India quantum initiatives
India is actively building capabilities in quantum technology. The National Quantum Mission aims to create an indigenous quantum ecosystem with dedicated research hubs.
The Quantum-Enabled Science and Technology (QuEST) programme by DST supports research and talent development in this field. It helps train young scientists in quantum technologies.
Several states have also launched initiatives such as Amaravati Quantum Valley (AQV) in Andhra Pradesh, Karnataka Quantum Mission, and Telangana Quantum Strategy.
Static GK fact: The National Quantum Mission was approved in 2023 with a significant budget outlay to boost research.
Future outlook
The PQC roadmap marks a proactive step toward future-ready cybersecurity. It ensures India stays ahead in protecting digital infrastructure from emerging threats.
As quantum computing evolves, early adoption of secure cryptographic standards will be essential. This roadmap strengthens India’s position in global digital security frameworks.
