Exam2: Problem 6 Previous Problem Problem List Next Problem Consider the following two methods for producing a stream cipher. In one method we define the ith block of keystream as AES(r:) where k is a 128-bit key, ro = 1 and ri1 = ri +1. The counter variable r in this scheme is a 64 bit integer. In another method we define the ith block of keystream as AES (r;) where r; is the įth 64 bit integer yielded by a CSPRNG seeded with k. How long will it take before the first method repeats a keystream block? How long will it take, roughly, before the second method repeats a keystream block? If you had to use one of these exactly as described, which one would you choose?
