Definition ∞ A pseudorandom generator is an algorithm that produces sequences of numbers that approximate the properties of true random numbers. While not truly random, these generators produce outputs that are computationally indistinguishable from random sequences, given a small, truly random seed. They are essential components in cryptographic systems for generating keys, nonces, and other random-like values required for security protocols. The quality of a pseudorandom generator directly impacts the strength of the cryptographic system it supports.
Context ∞ Pseudorandom generators are fundamental to the security of digital assets and blockchain technology, particularly in cryptography, transaction signing, and smart contract execution. Discussions often highlight the importance of using cryptographically secure generators to prevent vulnerabilities that could compromise funds or data. Ongoing research focuses on developing new generators that offer enhanced security guarantees and efficiency, especially in the context of quantum computing threats.
