Why in News

  • The Union Minister for Consumer Affairs, Food & Public Distribution launched a timing network based on White Rabbit Technology at RRSL Bengaluru.
  • This network distributes Indian Standard Time (IST) across critical digital systems to establish secure national Digital Public Infrastructure (DPI).

What is the IST Dissemination Demonstration Network?

  • The IST Dissemination Demonstration Network is a secure, tamper-resistant system that distributes precise national time across digital infrastructure.
  • Three major organizations created this network jointly: the Department of Consumer Affairs, CSIR-NPL, and ISRO.
  • It delivers time signals linked to national standard UTC (NPLI) using White Rabbit (WR) Technology based on the Precision Time Protocol (PTP).
  • The infrastructure provides secure time synchronization for 5G/6G telecom networks, banking systems, smart power grids, transportation, and e-governance.
  • Engineers completed a successful pilot test by sending timing signals between RRSL Bengaluru and the NSE facility in Chennai.
  • White Rabbit Technology improves the IEEE 1588 Precision Time Protocol by adding precise timestamps to standard Ethernet networks.
  • This technology syncs network points over fiber optic cables with accuracy ranging from microseconds to nanoseconds.
  • Unlike satellite systems like GPS that face spoofing and signal loss risks, fiber-based White Rabbit Technology offers strong protection against cyber threats.

Significance of Precision Time Dissemination

  • It provides tamper-proof time signals for essential sectors like banking, 5G/6G telecom, power grids, and transportation.
  • Recognizing accurate time as Digital Public Infrastructure (DPI) protects stock trading algorithms and prevents timestamp manipulation during cyber attacks.
  • This initiative supports the "One Nation, One Time" mission and advances Viksit Bharat by reducing reliance on foreign satellite systems.
  • It strengthens Legal Metrology frameworks, simplifies business operations, and boosts global investor confidence in India's digital economy.

Time Generation and Dissemination of Indian Standard Time (IST)

  • CSIR-NPL generates UTC (NPLI) to maintain IST, linking national time to the BIPM in France.
  • The laboratory calculates IST (UTC+5:30) using five caesium atomic clocks and three hydrogen masers to achieve precision within ±2.8 nanoseconds.
  • Caesium atomic clocks ensure long-term stability, while hydrogen masers maintain accurate short-term timing.
  • GNSS technology uses satellite signals to keep time synchronized at nanosecond precision with global standards.
  • TWSTFT uses geostationary satellites to transfer precise time, supporting NavIC and international time networks.
  • The Network Time Protocol (NTP) distributes IST over the internet via time.nplindia.org for government and private systems.
  • Cybersecurity agency CERT-In requires critical computer infrastructure to synchronize with NPL or NIC time servers.

CSIR–National Physical Laboratory (CSIR–NPL)

  • Parliament established CSIR-NPL in 1947 as the official National Measurement Institute (NMI) of India.
  • The laboratory maintains national measurement standards and IST, making Indian measurements recognized internationally.
  • Under Make in India, it develops quantum standards and offers calibration services to industries, defense units, and research centers.
  • Key focus areas include Metrology, Quantum Science, Nanotechnology, Materials Science, and Environmental Monitoring.
