(a) Describe the computing power, in terms of how many keys/seconds can be checked, necessary to be able to find an AES-192 key on average in under 100 years? (b) Now suppose that a super-intelligent alien race gifts humanity a powerful su- percomputer that is a trillion trillion times faster than the combined computing resources of the planet which is roughly 108 operations per second. Assume that one key check one "operation." Related the computing power now to the value from part (a).
