For some applications (such as hash tables), it is important for the least significant bits of the hash values to be also universal. When a family is strongly universal, this is guaranteed: if is a strongly universal family with =, then the family made of the functions ′ for all is also strongly universal for ′. Unfortunately, the same is ...
In computer science, a family of hash functions is said to be k-independent, k-wise independent or k-universal [1] if selecting a function at random from the family guarantees that the hash codes of any designated k keys are independent random variables (see precise mathematical definitions below). Such families allow good average case ...
In cryptography a universal one-way hash function (UOWHF, often pronounced "woof") is a type of universal hash function of particular importance to cryptography. UOWHFs are proposed as an alternative to collision-resistant hash functions (CRHFs). CRHFs have a strong collision-resistance property: that it is hard, given randomly chosen hash ...
A universal function is a function that can, in some defined way, imitate all other functions. This occurs in several contexts: In computer science, a universal function is a computable function capable of calculating any other computable function. It is shown to exist by the utm theorem.
The term "family values" is often used in political discourse in some countries, its general meaning being that of traditional or cultural values that pertain to the family's structure, function, roles, beliefs, attitudes, and ideals, usually involving the "traditional family"—a middle-class family with a breadwinner father and a homemaker ...

It affirms the existence of a computable universal function, which is capable of calculating any other computable function. [1] The universal function is an abstract version of the universal Turing machine, thus the name of the theorem. Roger's equivalence theorem provides a characterization of the Gödel numbering of the computable functions ...
