science: Do one-way functions exist? (more unsolved problems in computer science) In computer science, a one-way function is a function that is easy...

a one-way compression function is a function that transforms two fixed-length inputs into a fixed-length output. The transformation is "one-way", meaning...

functions are a special case of one-way functions and are widely used in public-key cryptography. In mathematical terms, if f is a trapdoor function,...

such that h = hash(m). This concept is related to that of a one-way function. Functions that lack this property are vulnerable to preimage attacks. Second...

Look up one-way in Wiktionary, the free dictionary. One-way or one way may refer to: One-way traffic, a street either facilitating only one-way traffic...

predicate of a one-way function f is a predicate b (i.e., a function whose output is a single bit) which is easy to compute (as a function of x) but is...

exact one-third of an arbitrary angle. Hence the function which assigns the triple of an angle to a given angle can be thought of as a one-way function, the...

exponent e when given b, c, and m – is believed to be difficult. This one-way function behavior makes modular exponentiation a candidate for use in cryptographic...

mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the...

In cryptography a universal one-way hash function (UOWHF, often pronounced "woof") is a type of universal hash function of particular importance to cryptography...

A bijection, bijective function, or one-to-one correspondence between two mathematical sets is a function such that each element of the second set (the...

signatures is based on the security of the one-way hash function and the length of its output. For a hash function that generates an n-bit message digest...

theory, a loss function or cost function (sometimes also called an error function) is a function that maps an event or values of one or more variables...

existence of pseudorandom generators is related to the existence of one-way functions through a number of theorems, collectively referred to as the pseudorandom...

|f_{k}\rangle } In both cases f is a one-way quantum function that has the same properties as a classical one-way function. That is, the result is easy to...

("subdomains") on which the function may be defined differently. Piecewise definition is actually a way of specifying the function, rather than a characteristic...

One-way traffic (or uni-directional traffic) is traffic that moves in a single direction. A one-way street is a street either facilitating only one-way...

algorithm, credited to Leslie Lamport, uses a one-way function (call it f {\displaystyle f} ). This one-time password system works as follows: A seed...

a prime number. However, they left open the problem of realizing a one-way function, possibly because the difficulty of factoring was not well-studied...

universal one-way function is a function that is known to be one-way if one-way functions exist. In mathematics, a universal function is one that contains...

In statistics, one-way analysis of variance (or one-way ANOVA) is a technique to compare whether two or more samples' means are significantly different...

also uses one of two one-way functions, depending on the NTLM version; NT LanMan and NTLM version 1 use the DES-based LanMan one-way function (LMOWF),...

In this respect it is the hardware analog of a one-way function. The name "physical unclonable function" might be a little misleading as some PUFs are...

Manuel Blum and Michael Shub that is derived from Michael O. Rabin's one-way function. Blum Blum Shub takes the form x n + 1 = x n 2 mod M {\displaystyle...

ineffective against one-way hashes that include large salts. For example, consider a password hash that is generated using the following function (where "+" is...

distributed point function from another cryptographic primitive, a one-way function. In the other direction, if a distributed point function is known, then...

(cryptographically) secure PRNG can be constructed generically from any one-way function, this generic construction is extremely slow in practice, so is mainly...

a function that takes multiple arguments into a sequence of families of functions, each taking a single argument. In the prototypical example, one begins...

provably secure if the probability of security failure (e.g., inverting a one-way function, distinguishing cryptographically strong pseudorandom bits from truly...

In mathematics, the exponential function is the unique real function which maps zero to one and has a derivative equal to its value. The exponential of...
