Last Update:
π Quantum Leap in Digital Security by Indian Researchers
π Context:
β
Scientists at Raman Research Institute (RRI), Bengaluru, led by Dr. Urbasi Sinha, have developed quantum techniques to generate and certify true random numbers.
β
Marks a major breakthrough for hack-proof digital and online security.
π How It Works:
β
Traditional systems use pseudorandom numbers (algorithm-based, predictable).
β
True randomness comes from natural or physical quantum processes like photon behaviour.
β
Technique uses Leggett-Garg inequality and quantum entanglement β proving randomness is intrinsic and certifiable.
π Significance:
β
Enables creation of truly unpredictable encryption keys.
β
Strengthens cybersecurity for encryption, authentication, and national digital infrastructure.
β
RRI became the first lab globally to show certified true randomness in a loop-free quantum setup.
π Mains Question:
Discuss how advancements in quantum random number generation can enhance Indiaβs cybersecurity and data protection framework.
