Randomness in cryptography

Although 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 randomness is crucial in cryptographic applications - because it provides a way to create information that an adversary can´t learn or predict. It´s then the task of a good protocol designer to leverage this power in the best possible way to protect data and communication. In this paper, we´ll look at some basic uses of randomness in cryptography and briefly review the process of securely generating randomness
