In [[computer science]], a '''one-way function''' is a [[function (mathematics)|function]] that is easy to compute on every input, but hard to [[Inverse function|invert]] given the [[image (mathematics)|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 [[One-to-one function|one-to-one]] is not considered sufficient of a function for it to be called one-way (see Theoretical Definition, below).

In applied contexts, the terms "easy" and "hard" are usually interpreted relative to some specific computing entity; typically "cheap enough for the legitimate users" and "prohibitively expensive for any [[Black hat hacking|malicious agent]]s". One-way functions, in this sense, are fundamental tools for [[cryptography]], [[personal identification]], [[authentication]], and other [[data security]] applications. While the existence of one-way functions in this sense is also an open conjecture, there are several candidates that have withstood decades of intense scrutiny. Some of them are essential ingredients of most [[telecommunication]]s, [[e-commerce]], and [[Online banking|e-banking]] systems around the world.

It is not sufficient to make a function "lossy" (not one-to-one) to have a one-way function. In particular, the function which outputs the string of ''n'' zeros on any input of length ''n'' is ''not'' a one-way function. The reason is that an algorithm A which just outputs any string of
length ''n'' on input ''f''(''x'') does find a proper preimage of the output, even if it is not the input which was originally used to find the output string.

==Theoretical implications of one-way functions==
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. However, it is not known whether P≠NP implies the existence of one-way functions.

===The Rabin function (modular squaring)<ref name=Goldreich></ref>{{rp|57}}===
The '''Rabin function''', or squaring [[modular arithmetic|modulo]] <math>N=pq</math>, where <math>p</math> and <math>q</math> are primes is believed to be a collection of one-way functions. We write
to denote squaring modulo <math>N</math>: a specific member of the '''Rabin collection'''. It can be shown that extracting square roots, i.e. inverting the Rabin function, is computationally equivalent to factoring <math>N</math> (in the sense of [[polynomial-time reduction]]). Hence it can be proven that the Rabin collection is one-way if and only if factoring is hard. This also holds for the special case in which <math>p</math> and <math>q</math> are of the same bit length. The [[Rabin cryptosystem]] is based on the assumption that this [[Rabin one-way function|Rabin function]] is one-way.

<!--From this description, this is not a one-way function but rather a [[trapdoor function]]. What gives? -->
The function ''f'' takes a prime number ''p'' and an integer ''x'' between 0 and ''p''−1; and returns the remainder of 2<sup>''x''</sup> divided by ''p''. This [[discrete exponential]] function can be easily computed in time ''O''(''n''<sup>3</sup>) where ''n'' is the number of bits in ''p''. Inverting this function requires computing the [[discrete logarithm]] modulo ''p''; namely, given a prime ''p'' and an integer ''y'' between 0 and ''p''−1, find ''x'' such that 2<sup>''x''</sup> = ''y''. As of 2009, there is no published algorithm for this problem that runs in polynomial time. The [[ElGamal encryption]] scheme is based on this function.

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 one-to-one is not considered sufficient of a function for it to be called one-way (see Theoretical Definition, below).
The existence of such one-way functions is still an open conjecture. In fact, their existence would prove that the complexity classesP and NP are not equal, thus resolving the foremost unsolved question of theoretical computer science.[1]Primarily based on the most recent URA personal property value index (PPPI) flash estimates, we know that the PPPI, which represents the overall real property price development, has dipped in 2013Q4.

In applied contexts, the terms "easy" and "hard" are usually interpreted relative to some specific computing entity; typically "cheap enough for the legitimate users" and "prohibitively expensive for any malicious agents". One-way functions, in this sense, are fundamental tools for cryptography, personal identification, authentication, and other data security applications. While the existence of one-way functions in this sense is also an open conjecture, there are several candidates that have withstood decades of intense scrutiny. Some of them are essential ingredients of most telecommunications, e-commerce, and e-banking systems around the world.

A function f: {0, 1}* → {0, 1}* is one-way if f can be computed by a polynomial time algorithm, but for every randomized algorithmA which runs in time
polynomial in n=|x|, every polynomial p(n), and all sufficiently large n
where the probability is over the choice of x from the uniform distribution on {0, 1}n, and the randomness of A.
Note that, by this definition, the function must be "hard to invert" in the average-case, rather than worst-case sense. This is different from much of complexity theory (e.g., NP-hardness), where the term "hard" is meant in the worst-case.
It is not sufficient to make a function "lossy" (not one-to-one) to have a one-way function. In particular, the function which outputs the string of n zeros on any input of length n is not a one-way function. The reason is that an algorithm A which just outputs any string of
length n on input f(x) does find a proper preimage of the output, even if it is not the input which was originally used to find the output string.
Related concepts
A one-way permutation is a one-way function that is also a permutation—that is, a one-way function that is both injective and surjective. One-way permutations are an important cryptographic primitive, and it is not known if their existence is implied by the existence of one-way functions.
A trapdoor one-way function or trapdoor permutation is a special kind of one-way function. Such a function is hard to invert unless some secret information, called the trapdoor, is known.
A collision-free hash functionf is a one-way function that is also collision-resistant; that is, no randomized polynomial time algorithm can find a collision—distinct values x, y such that f(x) = f(y)—with non-negligible probability.[3]
Theoretical implications of one-way functions
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. However, it is not known whether P≠NP implies the existence of one-way functions.
The existence of a one-way function implies the existence of many other useful concepts, including:
The existence of one-way functions also implies that there is no natural proof for P≠NP.
Candidates for one-way functions
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.
Multiplication and factoring
The function f takes as inputs two prime numbers p and q in binary notation and returns their product. This function can be computed in O(n2) time where n is the total length (number of bits) of the inputs. Inverting this function requires finding the factors of a given integer N. The best factoring algorithms known run in time, which is only pseudo-polynomial in , the number of bits needed to represent N.
This function can be generalized by allowing p and q to range over a suitable set of semiprimes. Note that f is not one-way for arbitrary p,q>1, since the product will have 2 as a factor with probability 3/4.
The Rabin function (modular squaring)[1]Primarily based on the most recent URA personal property value index (PPPI) flash estimates, we know that the PPPI, which represents the overall real property price development, has dipped in 2013Q4. That is the first dip the market has seen within the final 2 years.

The Rabin function, or squaring modulo, where and are primes is believed to be a collection of one-way functions. We write
to denote squaring modulo : a specific member of the Rabin collection. It can be shown that extracting square roots, i.e. inverting the Rabin function, is computationally equivalent to factoring (in the sense of polynomial-time reduction). Hence it can be proven that the Rabin collection is one-way if and only if factoring is hard. This also holds for the special case in which and are of the same bit length. The Rabin cryptosystem is based on the assumption that this Rabin function is one-way.
Discrete exponential and logarithm
The function f takes a prime number p and an integer x between 0 and p−1; and returns the remainder of 2x divided by p. This discrete exponential function can be easily computed in time O(n3) where n is the number of bits in p. Inverting this function requires computing the discrete logarithm modulo p; namely, given a prime p and an integer y between 0 and p−1, find x such that 2x = y. As of 2009, there is no published algorithm for this problem that runs in polynomial time. The ElGamal encryption scheme is based on this function.
Cryptographically secure hash functions
There are a number of cryptographic hash functions that are fast to compute like SHA 256. Some of the simpler versions have fallen to sophisticated analysis, but the strongest versions continue to offer fast, practical solutions for one-way computation. Most of the theoretical support for the functions are more techniques for thwarting some of the previously successful attacks.
Elliptic curves
Elliptic curves are sets of integers satisfying y^2=(x^3+ax+b) mod p. Defining a form of addition between 2D points on curves, and scalar-point multiplication as sequences of addition, leads to R=kP for points R,P and scalar k. If k and P are known, it is easy to compute R. But if R and P are known, it is assumed to be hard to compute k.
There is an explicit function f that has been proved to be one-way, if one-way functions exist.[4] In other words, if any function is one-way, then so is f. Since this function was the first combinatorial complete one-way function to be demonstrated, it is known as the "universal one-way function". The problem of determining the existence of one-way functions is thus reduced to the problem of proving that this specific function is one-way.
