Security proof for PRNG

jp flag

Could you help to find an example of where the next kind of proof is performed, please? "if we can distinguish the randomly generated bits of a PRNG from a random sequence, then we can distinguish the underlying block cipher/permutation from a random permutation"

A construction where you would see this kind of proof summary is counter mode with a fixed start using the random input as the key, i.e. $G(x)=E_x(0)\|E_x(1)\|E_x(2)\|E_x(3)\|\ldots$

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
