81Password — For other uses, see Password (disambiguation). A password is a secret word or string of characters that is used for authentication, to prove identity or gain access to a resource (example: an access code is a type of password). The password… …
82Dynamic perfect hashing — In computer science, dynamic perfect hashing is a programming technique for resolving collisions in a hash table data structure.[1][2][3] This technique is useful for situations where fast queries, insertions, and deletions must be made on a… …
83Digital signature — This article is about secure cryptographic signatures. For simple signatures in digital form, see Electronic signature. A digital signature or digital signature scheme is a mathematical scheme for demonstrating the authenticity of a digital… …
84Password cracking — is the process of recovering passwords from data that has been stored in or transmitted by a computer system. A common approach is to repeatedly try guesses for the password. The purpose of password cracking might be to help a user recover a… …
85Collision resistance — is a property of cryptographic hash functions: a hash function is collision resistant if it is hard to find two inputs that hash to the same output; that is, two inputs a and b such that H(a) = H(b), and a ≠ b.[1]:136 Every hash function with… …
86UOWHF — In cryptography a Universal One Way Hash Function (UOWHF), often pronounced woof , is a cryptographic hash function. UOWHF s are proposed as an alternative to CRHF s. Collision Resistant Hash Functions (CRHF) are based on the stronger assumption… …
87SUHA — In computer science, SUHA (Simple Uniform Hashing Assumption) or the Uniform Hashing Assumption is a basic assumption that facilitates the mathematical analysis of hash tables. The assumption states that a hypothetical hashing function will… …
88Kryptologische Hashfunktion — Eine kryptologische Hashfunktion oder kryptographische Hashfunktion ist eine spezielle Form der Hashfunktion, welche zusätzlich kollisionsresistent oder eine Einwegfunktion (oder beides) ist. Eine Hashfunktion ist eine Funktion, die eine… …
89SHA-3 — NIST hash function competition La NIST hash function competition est une compétition organisée par la NIST afin de trouver une nouvelle fonction de hachage (SHA 3) destinée à remplacer les anciennes fonctions SHA 1 et SHA 2 Sommaire 1… …
90List of terms relating to algorithms and data structures — The [http://www.nist.gov/dads/ NIST Dictionary of Algorithms and Data Structures] is a reference work maintained by the U.S. National Institute of Standards and Technology. It defines a large number of terms relating to algorithms and data… …
