A team from the Indian Institute of Science (IISc) has developed a true random number generator (TRNG). This can improve data encryption and provide improved security for sensitive digital data such as credit card details, passwords and other personal information.<\/p>\n
Everything a person does on the internet is encrypted for security. The strength of this encryption depends on the quality of random number generation.<\/p>\n
Encrypted information can be decoded only by authorised users who have access to a cryptographic \u2018key\u2019. But the key needs to be unpredictable and, therefore, randomly generated to resist hacking.<\/p>\n
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.<\/p>\n
In contrast, a TRNG device extracts random numbers from inherently random physical processes, making it more secure.<\/p>\n
In IISc’s TRNG device, random numbers are generated using the random motion of electrons.\u00a0The random motion of electrons consists of an artificial electron trap constructed by stacking atomically-thin layers of materials like black phosphorus and graphene.<\/p>\n
The current measured from the device increases when an electron is trapped and decreases when it is released.<\/p>\n
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.<\/p>\n
Standard tests for cryptographic applications are designed by the US National Institute of Standards and Technology (NIST). Min-entropy<\/strong> is a parameter used to measure the performance of TRNGs. Its value ranges from 0 (completely predictable) to 1 (completely random).<\/p>\n IISC’s TRNG showed a record-high min-entropy of 0.98, a significant improvement over previously reported values, which were around 0.89. Further, this TRNG is also more compact than its bulkier counterparts.<\/p>\n Source:\u00a0<\/b>The post is based on the article \u201cIISc develops device to improve data security\u201d\u00a0<\/b>published in\u00a0The Hindu<\/strong>\u00a0<\/b>on 28th May 2022.<\/b><\/p>\n","protected":false},"excerpt":{"rendered":" What is the News?
