You are trying to crack DES keys and AES keys with a PC that has a 3 Gigahertz processor. Assume that your processor can operate at 100 Million Instructions per second. Assuming that you can test each key with [6 steps times 16 cycles =) 96 instructions, estimate the amount to time necessary to crack a DES encryption by testing all 2^56 possible keys. Make a similar estimate for a 128-bit AES key, assuming you can test each of the 2^128 AES keys with [4 steps times 10 cycles =] 40 instructions. 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. Do some research on how DES was actually cracked in 1997-98 and compare what was done with your DES calculations. Considering your answer to part 2, is it feasible to use the approach used in cracking DES to crack AES
