Assume that your processor can operate at 100 Million Instructions per second. Assuming that you can test each key with [4 steps X 10 cycles] =40 instructions, estimate the amount to time necessary to crack a AES encryption by testing all keys.
2) Using Moore’s law, which says processors double in power approximately every two years, forecast approximately how many years it will be before a 128-bit AES key could be cracked in a week of processing.

At the same time, if one key was verified in 40 instructions, since the number of instructions doubles, the new processor checks one key in 20 instructions; so within one second the new processor is able of verifying a number of keys 4 times bigger than previous; thus the time to crack AES decreases by 4 times and this only after two years)....
