Diffie–Hellman (DH) key exchange[nb 1] is a mathematical method of securely generating a symmetric cryptographic key over a public channel and was one of the first public-key protocols as conceived by Ralph Merkle and named after Whitfield Diffie and Martin Hellman. [1][2] DH is one of the earliest practical examples of public key exchange ...
t. e. The Enigma machine was used commercially from the early 1920s and was adopted by the militaries and governments of various countries—most famously, Nazi Germany. Cryptanalysis of the Enigma ciphering system enabled the western Allies in World War II to read substantial amounts of Morse-coded radio communications of the Axis powers that ...
The Emishi (), also called Ebisu and Ezo, were a people who lived in parts of northern Honshū in present-day Japan, especially in the Tōhoku region.. The first mention of the Emishi in literature that can be corroborated with outside sources dates to the 5th century AD, [citation needed] in which they are referred to as máorén (毛人—"hairy people") in Chinese records.
Public-key cryptography, or asymmetric cryptography, is the field of cryptographic systems that use pairs of related keys. Each key pair consists of a public key and a corresponding private key. [1][2] Key pairs are generated with cryptographic algorithms based on mathematical problems termed one-way functions.
Example of a Key Derivation Function chain as used in the Signal Protocol.The output of one KDF function is the input to the next KDF function in the chain. In cryptography, a key derivation function (KDF) is a cryptographic algorithm that derives one or more secret keys from a secret value such as a master key, a password, or a passphrase using a pseudorandom function (which typically uses a ...

Zobrist hashing (also referred to as Zobrist keys or Zobrist signatures [1]) is a hash function construction used in computer programs that play abstract board games, such as chess and Go, to implement transposition tables, a special kind of hash table that is indexed by a board position and used to avoid analyzing the same position more than once.
