TRUE RANDOM NUMBER GENERATOR (TRNG)

May 28, 2022

A team at the Department of Electrical Communication Engineering (ECE), Indian Institute of Science (IISc) has developed a true random number generator (TRNG).

About:

  • This can improve data encryption and provide improved security for sensitive digital data such as credit card details, passwords and other personal information. The study describing the device has been published in the journal ACS Nano.
  • Cryptographic keys are typically generated in computers using pseudorandom number generators, which rely on mathematical formulae or pre-programmed tables to produce numbers that appear random but are not. In contrast, a TRNG extracts random numbers from inherently random physical processes, making it more secure.
  • In IISc’s TRNG device, random numbers are generated using the random motion of electrons.
  • It consists of an artificial electron trap constructed by stacking atomically-thin layers of materials like black phosphorus and graphene.
