WebAlthough more formal definitions of randomness exist, a colloquial one will suffice here: a random process is one whose consequences are unknown. Intuitively, this is why … WebRandomness extractors in cryptography. One of the most important aspects of cryptography is random key generation. It is often necessary to generate secret and random keys from sources that are semi-secret or which may be compromised to some degree. By taking a single, short (and secret) random key as a source, an extractor can be used to ...
