Computers and Number Crunching Phenomena

Ever wondered how some numbers are magically generated by computers in frequent uses such as cryptographic keys, interactive games, security applications etc. Day by day, we strive toward betterments in technology and one of the milestones we covered was how the computer was able to pick a single or even a collection of numbers or alphabets.

One of the methods to produce purely random numbers is with the help of thermal noise. Thermal Noise is obtained from fluctuations in a resistor that generates a voltage source, thus providing us a purely random output.

Similar techniques to generate an arbitrary output such as Atmospheric Noise, Nuclear Decay are also popular in the Computer Science fraternity. What makes Hardware Random Number Generation more reliable is that there is no requirement for pseudo-random techniques like hash algorithms or searching and sorting as our readings are dependent on natural properties that keep changing over time.

It is commonly used in Internet Encryption Protocol such as Transport Layer Security and expected to be an integral part of decentralized projects in forthcoming times.
