Q. With reference to True Random Number Generator (TRNG), consider the following statements;
1.The random numbers are typically generated in computers using pseudorandom number generators, which rely on mathematical formulae.
2.Min-entropy is a parameter used to measure the performance of TRNGs
Which of the statements given above is/are correct?
Statement 1 is incorrect: 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 device extracts random numbers from inherently random physical processes, making it more secure.
For instance, IISc’s TRNG device, random numbers are generated using the random motion of electrons. The random motion of electrons consists of an artificial electron trap constructed by stacking atomically-thin layers of materials like black phosphorus and graphene.
Statement 2 is correct: Standard tests for cryptographic applications are designed by the US National Institute of Standards and Technology (NIST). Min-entropy is a parameter used to measure the performance of TRNGs. Its value ranges from 0 (completely predictable) to 1 (completely random).
