below for your convenience). The correct answers will be provided after the a 1. Define G(s):= s/Is where || denotes concatenation. Describe and analyze an attack showing that G is not a pseudorandom generator. 2. Let G be a pseudorandom generator. In each of the following cases, say whether G' is necessarily a pseudorandom generator. If yes, give a proof; if not, show a counterexample. 1. Define G'(s):=G(s) where's is the complement of s. 2. Define G'(s):= G(5) 3. Define G'(s):= G(Ols| |1 5) 4. Define G'(s):= G(s)|IG(s + 1)
