Cryptographic one way function
WebFeb 24, 2024 · Cryptographic Hash is a Hash function that takes random size input and yields a fixed-size output. It is easy to calculate but challenging to retrieve the original … WebIn cryptography, a one-way compression function is a function that transforms two fixed-length inputs into a fixed-length output. [1] The transformation is "one-way", meaning that it is difficult given a particular output to compute inputs which compress to that output.

In computer science, a one-way function is a function that is easy to compute on every input, but hard to invert given the image of a random input. Here, "easy" and "hard" are to be understood in the sense of computational complexity theory, specifically the theory of polynomial time problems. Not being … See more A function f : {0,1} → {0,1} is one-way if f can be computed by a polynomial time algorithm, but any polynomial time randomized algorithm $${\displaystyle F}$$ that attempts to compute a pseudo-inverse for f … See more The following are several candidates for one-way functions (as of April 2009). Clearly, it is not known whether these functions are indeed one-way; but extensive research has so far failed to produce an efficient inverting algorithm for any of them.

One-way permutations … See more If f is a one-way function, then the inversion of f would be a problem whose output is hard to compute (by definition) but easy to check (just by computing f on it). Thus, the existence of a one-way function implies that FP≠FNP, which in turn implies that P≠NP. … See more There is an explicit function f that has been proved to be one-way, if and only if one-way functions exist. In other words, if any function is one-way, then so is f.
