Faster supercomputer (as per Wikipedia): 10.51 Pentaflops = 10.51 x 1015 Flops [Flops = Floating point operations per second]
No. of Flops required per combination check: 1000 (very optimistic but just assume for now)
No. of combination checks per second = (10.51 x 1015) / 1000 = 10.51 x 1012
No. of seconds in one Year = 365 x 24 x 60 x 60 = 31536000
No. of Years to crack AES with 128-bit Key = (3.4 x 1038) / [(10.51 x 1012) x 31536000]
= (0.323 x 1026)/31536000
= 1.02 x 1018
= 1 billion billion years
If we can implement quantum theory into real life...we would have communication methods faster than light. (Entanglement) However we are not there yet.
