Q4 (8 points) Let G(s)= (sl) for some t. Consider the following experiment: The PRG indistinguishability experiment PRGA,G(n): (a) A uniform bit be {0,1) is chosen. If b =0 then choose a uniform r {0,1}"); if b = 1 then choose a uniform s {0,1}" and set : G(s). (b) The adversary A is given r. and outputs a bit b. (c) The output of the experiment is defined to be 1 if bb, and 0 otherwise. Provide a definition of a pseudorandom generator based on this experiment, and prove that your definition is equivalent to the definition discussed in class (Soe slide titled Pseudo Random Number Generator: Definition ) (That is, show that G satisfies your definition if and only if it satisfies the definition discussed in the class.)
