Post-Quantum Cryptography: DST Pushes Quantum-Safe Encryption for Critical Sectors

Context: Post-Quantum Cryptography
DST task force recommended phased shift to Post-Quantum Cryptography (PQC) for critical sectors as future quantum computers may break current encryption systems.

Post-Quantum Cryptography

  • Encryption algorithms designed to resist attacks from quantum computers.
  • Protects banking, telecom, defence and governance data from future quantum threats.

Quantum Computing Basics

  • Classical computers use bits; quantum computers use qubits.
  • Qubits use superposition and entanglement, enabling very high-speed computation.

Quantum-Safe Encryption Concepts

  • Current public-key encryption systems like RSA and ECC may become vulnerable to quantum attacks.
  • “Harvest now, decrypt later” risk means data stolen today may be decrypted in future using quantum computers.
  • Quantum-safe encryption uses algorithms resistant to quantum attacks.

National Quantum Mission

  • Approved in 2023 with outlay of ₹6,003.65 crore till 2030-31.
  • Aim: Develop quantum computers with 50–1000 physical qubits.
  • Includes four Thematic Hubs in academic and R&D institutions.
  • Focus areas: Quantum computing, communication, sensing, and materials.

About the UPSC Civil Services Examination (UPSC CSE)

The UPSC Civil Services Examination (CSE) is one of the most competitive and esteemed examinations in India, conducted by the Union Public Service Commission to recruit officers for services such as the Indian Administrative Service (IAS), Indian Police Service (IPS), Indian Foreign Service (IFS), and others. The exam comprises three stages — Prelims, Mains, and the Personality Test (Interview) — designed to test a candidate’s knowledge, aptitude, decision-making, and leadership skills.


How to Prepare Effectively for UPSC CSE

Cracking the UPSC CSE requires a deep understanding of the syllabus, consistent revision, structured answer writing, and smart test-taking strategies. The Prelims test analytical and conceptual clarity, the Mains focuses on critical thinking, articulation, and subject mastery, while the Interview assesses presence of mind, ethical judgment, and personality traits relevant to public service.
