- Recently, Researchers at the Indian Institute of Science (IISc) have developed a True Random Number Generator (TRNG) with a “record-breaking” performance parameter.
About True Random Number Generator (TRNG) Device
- The study describing the TRNG device has been published in the journal ACS Nano.
- The performance of the TRNG device on the standard tests for cryptographic applications designed by the US National Institute of Standards and Technology (NIST) has exceeded their expectations.
- IISc will provide better protection for sensitive digital data such as credit card details, passwords, and more using TRNG devices.
- It can improve data encryption and provide improved security for sensitive digital data such as credit card details, passwords, and other personal information.
- Encrypted information can be decoded only by authorised users who have access to a cryptographic ‘key’.
- 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.
- Encrypted information can be decoded only by authorised users who have access to a cryptographic ‘key’.
- In IISc’s TRNG device, random numbers are generated using the random motion of electrons.
- The current measured from the TRNG device increases when an electron is trapped, and decreases when it is released.
- Since electrons move in and out of the trap in a random manner, the measured current also changes randomly.
- The timing of this change determines the generated random number.
