The End of Encryption?

An anonymous reader writes "The encryption algorithms that make virtually all electronic commerce possible work only because certain mathematical problems are very, very hard to solve. But some mathematicians are trying to prove that there's really no difference between 'hard' and 'not hard' problems--known in the math biz as P and NP. In an article on TechnologyReview.com, Simson Garfinkel spells out the real-world consequences of this mathematical conundrum."

    The one way to tell for sure if the good guys win, is if the Republican National Committee goes bankrupt and GreenPeace gets a sizable donation. Also, you might see Sydney Poitier in Tahiti and Dan Akroyd in a brand spanking new RV.

    The ability to feed the correct message back from that universe to the rest of us may be a bit tricky, but could perhaps be done by having the individual in the lucky universe set all quanta to 0xFF in a bank of LEDs in a pattern representing the plaintext.

    One important class of problems which should be included in this discussion is the class of P Complete problems.

    These are problems for which there exists a polynomial time reduction to the P Problem, which is the ability to optimally distribute P straight pegs in U linearly arranged slots (where P less than or equal to U), so as to maximize the distance between pegs.

    For example, for (P=2, U=5), the optimal solution is a peg at the first and last slots. For (P=3, U=5), optimal is U0, U2, U4, etc.

    It can be shown that any problem which can be reduced in polynomial time to straight men at a row of urinals is P Complete.
