Comments on Why Is how to find out a pdf is photoshoped or not NSA Moving Away from Elliptic Curve Cryptography? Why Is the NSA Moving Away from Elliptic Curve Cryptography?
NSA’s plans to move to quantum-resistant algorithms for its own cryptographic needs. They range from some new cryptanalysis of ECC to a political need after the DUAL_EC_PRNG disaster — to the stated reason of quantum computing fears. Feel free to skip over the math if it gets too hard, but keep going until the end. I am not aware that physicists have properly answered this question yet.
If it takes more energy than the sun, or trillions of years to break a single RSA or ECC key with a quantum computer, then this exercise of migrating into alternative public key algorithms is pointless. One might as well work on designing crypto systems that take into account time travel. Not PFS, but dealing with brute force methods in which after countless years the results can be transmitted to the past. Now they’re going to have to kill your grandfather. I think one might be hard pressed to label any EPR based phenomena as ‘not time travel’? Am I mistaken about the known or unknown limitations of entanglement here? I mean, just because we haven’t found a way to measure or make proof backwards shouldn’t discredit the potential to find it – we do have seemingly instantaneous transmission of ‘data’ in these instances don’t we.
