Question: In the text, we computed that a cipher-breaking machine with a million processors that could analyze a key in 1 nanosecond would take 10 16

In the text, we computed that a cipher-breaking machine with a million processors that could analyze a key in 1 nanosecond would take 10¹⁶ years to break the 128-bit version of AES. Let us compute how long it will take for this time to get down to 1 year, still along time, of course. To achieve this goal, we need computers to be 10¹⁶ times faster. If Moore’s Law (computing power doubles every 18 months) continues to hold, how many years will it take before a parallel computer can get the cipher breaking time down to a year?
