hash-function
71Universal hashing — is a randomized algorithm for selecting a hash function F with the following property: for any two distinct inputs x and y , the probability that F(x)=F(y) (i.e., that there is a hash collision between x and y ) is the same as if F was a random… …
72Merkle-Damgård construction — In cryptography, the Merkle Damgård construction or Merkle Damgård hash function is a method to build cryptographic hash functions. All popular hash functions follow this generic construction.A cryptographic hash function must be able to process… …
73Collision attack — In cryptography, a collision attack on a cryptographic hash tries to find two arbitrary inputs that will produce the same hash value, i.e. a hash collision. In contrast to a preimage attack, neither the hash value nor one of the inputs is… …
74crypt (Unix) — In Unix computing, crypt is the name of both a utility program and a C programming function. Though both are used for encrypting data, they are otherwise essentially unrelated. To distinguish between the two, writers often refer to the utility… …
75Locality sensitive hashing — (LSH) is a method of performing probabilistic dimension reduction of high dimensional data. The basic idea is to hash the input items so that similar items are mapped to the same buckets with high probability (the number of buckets being much… …
76Algorithmic efficiency — In computer science, efficiency is used to describe properties of an algorithm relating to how much of various types of resources it consumes. Algorithmic efficiency can be thought of as analogous to engineering productivity for a repeating or… …
77MinHash — In computer science, MinHash (or the min wise independent permutations locality sensitive hashing scheme) is a technique for quickly estimating how similar two sets are. The scheme was invented by Andrei Broder (1997),[1] and initially used… …

79Crypt (Unix) — In Unix computing, crypt is the name of both a commonly available utility program and a C programming function. Though both are used for encrypting data, they are otherwise essentially unrelated. To distinguish between the two, writers often… …
