We assume that the computer has a 3GHz processor. Assume that the machine takes a 100 cycles per brute force substitution against a single 56-bit DES key. Time required to crack a 56-bit key DES encryption -> 2^56 key * 100 cycles / 60 sec / 60 min / 24 hrs / 365 days / 3000000000Hz 7205759403792793600/60/60/24/365/3000000000 => 76.16438 years Time required cracking a 128-bit key AES Encryption -> Assume the machine takes a 100 cycles per brute force substitution against a single 128-bit AES key. 2^128 key * 100 cycles / 60 sec / 60 min / 24 hrs / 365 days / 3000000000Hz => 359,676,102,360,200,472,965,684.305166 years According to Moore's Law -> Processors double in power approximately every two years. For a 128-bit AES encryption to be cracked in a week of processing -> 3,6,12,24,48,96,192,384,768,1536. ....... With a processor speed of 58,028,439,341,502,200,385.8968 Peta Hertz, a 128-bit AES encryption could be cracked in approximately a week's time. According to Moore's Law, it takes a total of 150 years from now.
