WebOct 24, 2024 · In cryptography, randomness is the beacon by which to measure the security of ciphers. A cipher must be random to be secure; otherwise, all operations would be predictable, therefore, insecure because any attacker could emulate the encryption (again, because it is public) and predict the outcome. WebThis page lists online resources for collecting andprocessing crypto-strength randomness. Seethis paperfor a motivating example of why this is important to get right.

WebJan 6, 2014 · Random weakness In some cases, even this might not be enough. For example, TrueCrypt, like most cryptographic systems, use the system's random number generator to create secret keys. If an attacker can control or predict the random numbers produced by a system, they can often break otherwise secure cryptographic algorithms.
