Random Number Generator: How Do Computers Generate Random Numbers?
As an alternative to true random numbers, the second method of generating random numbers involves computational algorithms that can produce apparently random results. Why apparently random? Because the end results obtained are in fact completely determined by an initial value also known as the seed value or key. Therefore, if you knew the key value and how the algorithm works, you could reproduce these seemingly random results.

Random number generation – Wikipedia
Random number generation is a process by which, often by means of a random number generator, a sequence of numbers or symbols that cannot be reasonably predicted better than by random chance is generated. This means that the particular outcome sequence will contain some patterns detectable in hindsight but unpredictable to foresight. True random number generators can be hardware random-number generators that generate random numbers, wherein each generation is a function of the …

How Computers Generate Random Numbers – How-To Geek
There are two categories of random numbers — true random numbers and pseudorandom numbers — and the difference is important for the security of encryption systems. Computers can generate truly random numbers by observing some outside data, like mouse movements or fan noise, which is not predictable, and creating data from it. This is known as entropy. Other times, they generate pseudorandom numbers by using an algorithm so the results appear random, even though …

How random are the random numbers generated by your computer?
There are two common methods for generating random numbers from a computer: Pseudo-Random Number Generators (PRNGs) and True Random Number Generators (TRNGs). To generate PRNGs, a computer uses a seed number and an algorithm to generate numbers that seem to be random, but are actually predictable. The outputs of PRNGs may result into a reasonably complex pattern, but since they operate on the basis of a predefined algorithm, the numbers they produce are not truly random. Unlike PRNGs, TRNGs …

What Are Random Numbers and How Are They Used? – WhatIs.com
The first step to generate a random number sequence is to choose X 0, m, a and c. The algorithm will then initialize the required number of random numbers to be generated, as well as defining the storage to store the generated random number sequence. The 0 index of the vector will be initialized with the seed value.

What Are Random Number Generators and Why Are They Important?
The simplest way to generate a random number is to flip a coin. Ideally, there is no way to predict what the result may be – heads or tails should occur about 50% of the time. The problem with coins is that they are biased by nature: they have different patterns on their sides so they will favour one of the sides. Generating truly random numbers is much harder – and much more important than a coin flip.

How does a cryptographically secure random number generator work?
In order for a random number generator to be considered cryptographically secure, in needs to be secure against attack by an adversary who knows the algorithm and a (large) number of previously generated bits. What this means is that someone with that information can’t reconstruct any of the hidden internal state of the generator and give predictions of what the next bits produced will be with …
