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

Mentions lack of modern technology adoption (barcodes, RFID) in food supply chains, highlighting that digital/logistics technologies are considered part of food infrastructure.

A student could note that if digital identification/authentication technologies are being applied to PDS logistics, they should check whether security frameworks like PKI are referenced in government digital supply-chain documents.

Emphasises the role of science and technology in agriculture to ensure food security and that farmers need access to state-of-the-art technologies and information.

One could reasonably look for specific digital-security mechanisms (e.g., PKI) in official technology deployments for agricultural information systems and farmer-facing platforms.

Notes 'dynamic changes in the technological environment' as a challenge for infrastructure, implying that modern infrastructure discussions include consideration of new digital technologies and their management.

A student could infer that infrastructure policy documents addressing technological change might mention security frameworks such as PKI when discussing digital components of food infrastructure.

Describes the Public Distribution System (PDS) and the National Food Security Act as central components of India's food-security infrastructure.

Given PDS is the principal food-security system, one could investigate PDS digitisation/IT initiatives (e.g., e-PDS) to see if they reference PKI for authentication or secure transactions.

Defines food security as depending on availability, accessibility, affordability and on the PDS and government action — suggesting government-run systems where digital controls/security might be applied.

A student can combine this with knowledge that many government services use digital authentication, and thus check PDS/e-governance security standards for PKI mentions.

Describes the government's push for 'Digital Public Infrastructure' built on digital identity (Aadhaar) and mobile/financial linkages — a framework where authentication and secure digital transactions are central.

A student could note that PKI is a common technical means for authentication and secure transactions, so they should check digital public infrastructure policies for mentions of PKI or certificate-based authentication in health/education services.

Mentions 'National Digital Health Blueprint' and digital initiatives for education (PM eVIDYA, DIKSHA), indicating explicit government programs to digitalize health and education delivery.

Combine this with the fact that digital health/education systems require secure identity and data protection — thus search these program documents for technical security standards like PKI.

Lists institutional infrastructure for 'smart cities' including e‑governance and banking/financial institutions — areas that typically rely on secure digital infrastructure and cryptographic trust services.

Use the smart city institutional list to hypothesize that secure trust frameworks (often implemented via PKI) would be relevant and then inspect smart city technical guidelines for PKI references.

Defines 'Social Infrastructure' as including schools and hospitals, tying education and healthcare to the broader concept of infrastructure that is being modernized.

A student can infer that when social infrastructure is digitalized (per other snippets), security mechanisms like PKI may be adopted and should be looked for in digitalization plans for schools/hospitals.

Emphasizes public spending on education and health as key components of inclusive growth, implying government-led development where standardized digital solutions could be applied.

Combine this policy emphasis with knowledge that governments often standardize security (e.g., PKI) across public services; thus check government procurement/specs for PKI in health/education projects.

This snippet highlights the large scale and importance of the Indian telecom sector, implying a need for secure digital systems to support millions of connections.

A student could infer that large telecom networks commonly require security frameworks (like PKI) and therefore check telecom regulations or operator documentation for explicit PKI usage.

It explicitly discusses 'Digital Public Infrastructure' (digital identity, bank linking, mobile penetration), showing government focus on foundational digital systems.

Given that PKI is a common building block of secure digital identity and services, a student could look up Indian digital-identity/DI projects (Aadhaar/UPI) or policy documents to see whether PKI is referenced.

Defines 'infrastructure' to include communication and notes economic infrastructure supports growth—linking communications with broader infrastructure planning.

A student could treat communications as part of infrastructure and then search telecom/communication policy texts for references to cryptographic infrastructures such as PKI.

Describes transport as a core infrastructure sector with multiple modes, implying increasing digitalization and the need for secure communications within transport systems.

One could reasonably check transport-sector digitalization plans (rail/air/road ITS) for standards or mentions of PKI for secure signalling, ticketing or communications.

Points to technology adoption gaps in logistics (barcodes, RFID, modern logistics), indicating areas where digital security and authentication mechanisms could be introduced.

A student could investigate logistics/transport technology initiatives to see if they recommend or adopt PKI-based authentication or digital certificates.
