WebWe outline constructions for both pseudo-random generators and one-way hash functions. These constructions are based on the exact TSP (XTSP), a special variant of the well known traveling salesperson problem. We prove that these constructions are secure if the XTSP is infeasible. Our constructions are easy to implement, appear to be fast, but require a large … 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. WebWe have now defined two functions that are hard to perform: computing the inverse of a one-way function and distinguishing the output of a pseudo-random function from a … destiny i am the fated villain

"WebMar 12, 2016 · A one way function is a function that processes the input in such a way that there is not an easy way to get back to to the input using only the output and knowledge of the function. When I say easy, I mean less than the expected security provided by the function to be practical, which may still be quite hard. " - Cryptographic one way function
