Summary of research on hash table and hash functionWith the increasing of information level, the data has been replaced computing as the center of Information Computing, the demand for storage has been increasing the volume of explosive growth trend,

  Public key cryptography system and RSA public key algorithm Abstract: This article briefly introduces the ideas and features of the public key cryptography system, and introduces the theoretical basis, working principle and implementation process

ArticleDirectory 3.1 c ++ Java 3.2 1. Hash Introduction Hash is a frequently used data structure to implement certain functions. In Java and C ++, there is a encapsulated Data Structure: C ++ STL map Java has hashmapTreemap. In

Hash Hash, the general translation to do "hash", there is a direct transliteration of "hash", is the arbitrary length of the input (also known as pre-mapping, pre-image), through the hash algorithm, transformed into a fixed-length output,

In the computational theory, there is no hash function, only one-way function is said. The so-called one-way function, is a complex definition, you can see the computational theory or cryptography data. The "Human" language describes the one-way

[Cryptography 02] cryptographic system principles and mathematical background In the previous article [cryptography], four theme topics briefly introduced the technical means used to achieve the confidentiality and integrity of information

a hash table, also known as a hash table, is a data structure that is accessed directly from a key value. That is, it accesses records by mapping key code values to a location in the table to speed up lookups. This mapping function is called a hash
