  • For secure communications, the keys should be pseudorandom to ensure they cannot be easily predicted.

  • So we'll address that today if A is pseudorandom and OK.

  • OK, so I want to say more about how you might go about proving this type of result and also what pseudorandom graph means over here.

Morphology

pseudorandom = random (semi-transparent) = pseudo + random

The word is built transparently from pseudo- plus random, but the result is a specialized technical term rather than a fully everyday meaning.

Etymology

The word pseudorandom combines pseudo- meaning 'false' and random meaning 'by chance'. So it describes numbers or results that look like they come 'by chance' but are actually made by a fixed rule, like a magician's trick that seems spontaneous but follows a secret pattern.
