Shuffling cards, throwing dice, flipping coins, and drawing straws are just some of the ways people try to randomize things traditionally. In today’s modern world, however, the contemporary and advanced application of these randomness devices can be easily found in random number generators.
As the name suggests, a random number generator (RNG) is a mathematical construct that is specifically designed to come up with a completely random set of numbers that should not showcase any patterns in their appearance or generation.
How Do Random Number Generators Work?
RNGs can be categorized depending on the kind of random number they generate. According to an article by How To Geek, those that generate pseudo-random numbers involve computational algorithms that can produce apparently random results. We say apparently random because the numbers are completely determined by an initial value.
On the other hand, true random number generators (TRNGs) rely on some outside data. The computer observes some type of physical phenomenon in order to ensure “pure randomness” from the universe. Some examples of these occurrences include the radioactive decay of an atom, telegraph noise, and other quantum and electromagnetic phenomena.
Where Are They Used?
Although we don’t normally notice it, RNGs are integrated into a wide array of things today. While some require pseudo-random numbers that allow for the reproduction of a certain sequence, others leverage true random numbers for their lack of predictability.
One of the most common applications of RNGs is in games. They play a big role in loot-focused games like Destiny, Borderlands, and Diablo. RNGs are also at the center of procedural generation or the process of creating game content through an algorithm. MakeUseOf’s feature on the application of RNGs in games also noted how this can be used in determining the chance percentage of certain actions or events, as well as in keeping speedruns interesting and fun.
Online casinos, too, rely on this technology to ensure fairness and excitement in their games. An article on online slots by Gala Spins highlights how sophisticated RNG software is present in every single slot game, which works in mere milliseconds to allow for random sequences — whether you are playing classic 3-reel slots or more dynamic 5 and 6-reel titles. Aside from ensuring fairness, this technology also helps determine bonus features like free spins and unique mechanics, which has helped push online slot gaming to new heights in both gameplay and popularity around the globe.
Last but certainly not least, the most ubiquitous application of RNG is cryptography. Cryptography can be defined as a method of storing and transmitting data in a particular form so that only those that are supposed to read and process them can. RNGs come into the picture when they are being leveraged to create a strong random key that can ensure the highest security and reliability possible. As explained in a post by IEEE Spectrum, through TRNGs, cryptographers will be able to produce unpredictable cryptographic keys. These, when combined with a secure method of distribution, can combat even the most capable hacker.
As the world becomes more and more reliant on everything online and digital, RNGs will become an even more crucial ingredient in strengthening cybersecurity, as well as in keeping varying types of games fun, exciting, and most importantly, fair.
