Hardware random number generator
Hardware random number generators are used in cryptography. They are a more secure alternative to pseudorandom number generators. The RAND Corporation began generating random digits with an electronic roulette wheel in 1947. It is still used today in Internet encryption protocols such as Transport Layer Security.
About Hardware random number generator in brief
A hardware random number generator is a device that generates random numbers from a physical process, rather than by means of an algorithm. Such devices are often based on microscopic phenomena that generate low-level, statistically random signals. Hardware random number generators are used in cryptography, where they are used to generate random cryptographic keys to transmit data securely. They are a more secure alternative to pseudorandom number generators, which use a deterministic algorithm to produce numerical sequences. The major use for hardwarerandom number generators is in the field of data encryption, for example to createrandom cryptographic keys and nonces needed to encrypt and sign data. The RAND Corporation began generating random digits with an electronic roulette wheel in 1947. It was a significant breakthrough because it delivered large numbers such as 100,000 Normal Digits with a five gated pulse and fed into a binary counter. The results of a long run from the RAND machine were filtered and converted into a large random numbers table, which was published in 1955 in the book A Random Digits, Normal Deviates with a Five gated Pulse and a five pulse per second. It is still used today in Internet encryption protocols such as Transport Layer Security. The main application for electronic hardwareRandom Number Generators is to generate cryptographic keys for secure data encryption and other applications.
