Suppose G : {0, 1 {0, 1 }21 is a secure pseudo-random generator. Describe what is wrong with each of the following attempt to build a pseudo-random generator with -bit seeds and 4X- bit outputs: l. G Sr), where IsLI = ISR (Do not worry about possibly being odd.) Suppose G : {0, 1 {0, 1 }21 is a secure pseudo-random generator.
