WebNov 6, 2024 · In cryptography, the term random means unpredictable. That is, a process for generating random bits is secure if an attacker is unable to predict the next bit with greater than 50% accuracy (in other words, no better than random chance). We can obtain randomness that is unpredictable using one of two approaches.
