Read this question in English

In India, the term "Public Key Infrastructure" is used in the context of

(a) Digital security infrastructure · (b) Food security infrastructure · (c) Health care and education infrastructure · (d) Telecommunication and transportation infrastructure

उत्तर और व्याख्या · explanation in English

Answer: (a) डिजिटल सुरक्षा आधारभूत संरचना

Public Key Infrastructure (PKI) is the digital security system behind digital signatures. In India, the Controller of Certifying Authorities (CCA) under the Information Technology Act runs it: the Root Certifying Authority of India sits at the top, and licensed Certifying Authorities issue Digital Signature Certificates below it.

  • ✓ (a) India's PKI is a hierarchy of trust starting at the Root Certifying Authority of India. Licensed CAs issue Digital Signature Certificates, which let people sign electronic records and be verified.
  • ✗ (b) Food security relates to grain storage, distribution and the PDS. PKI has nothing to do with it.
  • ✗ (c) Health and education infrastructure means hospitals and schools; PKI is a cryptographic trust system, not a service network.
  • ✗ (d) Telecommunication and transport infrastructure means networks and roads or railways; PKI is not one of these. It secures electronic communication rather than carrying it.

Remember · PKI = digital security infrastructure: Root CA of India, licensed CAs and Digital Signature Certificates under the IT Act, overseen by the CCA.
