What is a Random Number Generator – RNG?
A random number generator is simply a tool that produces numbers that do not follow any predetermined logic . In other words, they are “ random ”.
It is important to note that although these numbers are called "random", they are actually generated by an algorithm that follows a series of precise rules. This means that it is theoretically possible to predict which numbers will be generated, but this would require complete knowledge of the algorithm used and the current state of the generator.
History of the RNG
- The first electronic random number generator was created by mathematician John von Neumann in the 1940s. He used a random number generator to help develop the first general-purpose computer, the ENIAC .
- Since then, many other random number generators have been created, using a variety of algorithms and generator grain sources.
Applications of RNG
- Online Transactions : RNG is used to enhance the security of online transactions by generating security codes and secure passwords .
- Computing : RNG can be used to create security tokens that can be used to authenticate users and protect sensitive data during transmission.
- Cryptography: Random number generators are used to create encryption keys to ensure the security of online communications .
- Gambling: Random number generators are used in gambling games such as slots and card games to ensure impartial results .
- Video games: Random number generators are used in video games to create random events such as loot drops in role-playing games or enemies appearing in shooting games.
- Scientific simulations: Random number generators are used in scientific simulations to imitate randomness and variability in data.
- Data Analytics: Random number generators can be used to randomly select data samples for analysis .
How do Random Number Generators work?
There are many different algorithms that can be used to create random number generators, but they all follow a similar process. Here's how it generally works:
- An “initial state” is chosen, generally in the form of a number or sequence of numbers. This initial state is called “ generator grain ”.
- The algorithm uses the generator grain to produce a new random number, which is called a “ prime number ”.
- The prime number is used to update the generator grain , which is used to produce the next random number, and so on.
It is important to note that the generator grain should be chosen so that it is not predictable. If the generator grain can be predicted, then it is possible to predict the random numbers that will be generated by the generator.
Types of Random Number Generators
There are several types of random number generators, which differ in how they produce random numbers. Here are some examples:
- Pseudo-random number generators : These generators use an algorithm to produce numbers that appear to be random, but in reality are not. They are generally used when there is no need for truly random numbers, or when it is difficult to produce truly random numbers.
- Motion-based random number generators : These generators use sensors to detect physical movements, such as the movement of a mouse or joystick , and use these movements to produce random numbers.
- Noise-based random number generators : These generators use sensors to detect physical noises, such as wind noise or background noise from an environment, and use these noises to produce random numbers.
- Time-based random number generators : These generators use the current time or other measurements of time to produce random numbers.
Although each of these types of generators has its own advantages and disadvantages, they are all used in different situations depending on the needs of the application.
RNG in IT
RNG is used in many aspects of computing , including generating random numbers for passwords , encryption keys , and authentication tokens . It can also be used to simulate chance in computer programs , such as in video games or simulations.
On personal computers, RNG can be used to generate random numbers when installing software or operating systems , or when using encryption programs to protect files and communications.
It is important that random number generators used on personal computers are secure and cannot be easily predicted, in order to protect sensitive data and ensure system security . password generator software to create strong passwords and protect their online accounts.

RNG in video games
The use of RNG in video games is a way to create uncertainty and randomness in the events that occur in the game. This can be used to add variety and interest to the game making each part unique.
There are several different ways that RNG can be used in video games. For example, it can be used to determine which enemies appear in a level, which loots are generated for the player, or to determine the results of certain player actions (such as hitting an enemy or trying to hack a system).
It's important that random number generators used in video games are balanced and fair, so that players don't feel like the game is rigged against them. This can be accomplished by using robust RNG algorithms and performing testing to ensure that the results generated are balanced.
Controversy surrounding microtransactions with LA RNG
Microtransactions have been the center of controversy in the gaming world due to their connection to RNG . Indeed, some players have accused games that use microtransactions of favoring players who spend real money by giving them access to more powerful game elements via RNG. This can make it seem like the game is rigged and that only players who spend money have a chance of succeeding.
This practice, known as “ loot boxing ,” has sparked much controversy and has been criticized for exploiting players' psychology and tricking them into spending real money in the game. Some governments have even taken steps to regulate the use of these microtransactions, considering that they may be similar to resale of chance and therefore subject to strict regulations.
RNG in cryptocurrency
RNG plays an important role in creating and securing cryptocurrency transactions .
When a cryptocurrency transaction is made, a new block is added to the blockchain (also called “ blockchain ”). To add this new block to the chain securely, it is necessary to solve a complex mathematical problem called “proof of work”. This proof of work usually involves calculating hashes of a large amount of data, which can be a very time-consuming and expensive process in terms of computing power .
To make this process faster and less expensive, some cryptocurrency protocols use what is called “ proof-of-stake mining ”. In this case, nodes (computers) in the blockchain are randomly selected to add the new block to the chain, using a random number generator to determine which node will be chosen.
It is important that this random number generator is secure and cannot be predicted so as to avoid fraud and hacking attacks . If an attacker were able to predict which node will be chosen to add the next block, they could try to forge transactions or take control of the blockchain.
Is RNG used for online payments?
Yes, banks often use RNG (random number generation) to generate random data, to enhance transaction security .
For example, when you make an online transaction , your bank may use a random generation system to create a unique security code , which will be sent to your mobile phone to verify your identity . This ensures that only the credit card holder can authorize the transaction , and prevents fraud.
Similarly, banks often use RNG to generate secure, random passwords when creating online accounts. This helps protect user accounts against hacking attempts .
Cyber attack on the RNG?
It is possible that a cyberattack aims to compromise a random number generation (RNG) system, in order to predict the data generated by this system and thus compromise the security of transactions or accounts protected by the RNG. However, it is difficult to know whether such cases actually took place, as this information is often confidential and not made public.
It is important to note that, in most cases, random number generation systems are designed to be very secure and it is difficult to predict the data they generate . Additionally, many companies and organizations implement security measures to protect their random generation systems from cyberattacks.
Conclusion
The RNG (Random Number Generator) is an essential tool for ensuring the security of computer systems and protecting sensitive data. It is used in many fields, such as computing, video games and online transactions.
However, there is a risk of cyberattack on RNG , because it is theoretically possible to predict the numbers produced by a random number generator by knowing the algorithm used and the current state of the generator. If an attacker can predict the numbers produced by a random number generator, they could use this information to hack systems or falsify transactions!
In summary, although RNG is an important tool for the security of online transactions and accounts, it is unclear whether cyberattacks have successfully compromised these random number generation systems.
As a precaution, updating software and using strong passwords can protect against possible attacks.
