Pseudorandomness refers to sequences of numbers that appear random but are generated by a deterministic process, such as an algorithm. These sequences are often produced by computer programs using initial values called seeds. While they mimic the properties of true randomness, they can be reproduced if the same seed is used, making them predictable. Pseudorandom numbers are widely used in various fields, including computer simulations, cryptography, and gaming. For example, in cryptography, secure communication relies on the unpredictability of these numbers to protect sensitive information. However, because they are not truly random, their security can be compromised if the generation method is known.
