1Message Authentication Code — Ein Message Authentication Code (MAC) dient dazu, Gewissheit über den Ursprung von Daten oder Nachrichten zu erhalten und ihre Integrität zu überprüfen.[1] MAC Algorithmen erfordern zwei Eingabeparameter, erstens die zu schützenden Daten und… …
2Cryptographic hash function — A cryptographic hash function (specifically, SHA 1) at work. Note that even small changes in the source input (here in the word over ) drastically change the resulting output, by the so called avalanche effect. A cryptographic hash function is a… …
3Challenge-response authentication — For the spam filtering technique, see Challenge response spam filtering. For other uses, see CRAM (disambiguation). In computer security, challenge response authentication is a family of protocols in which one party presents a question (… …
4Message authentication code — In cryptography, a message authentication code (often MAC) is a short piece of information used to authenticate a message. A MAC algorithm, sometimes called a keyed (cryptographic) hash function, accepts as input a secret key and an arbitrary… …
5Two-factor authentication — (TFA, T FA or 2FA) is an approach to authentication which requires the presentation of two different kinds of evidence that someone is who they say they are. It is a part of the broader family of multi factor authentication, which is a defense in …
6Digest access authentication — HTTP Persistence · Compression · HTTPS Request methods OPTIONS · GET · HEAD · POST · PUT · DELETE · TRACE · CONNECT Header fields Cookie · ETag · Location · Referer DNT · …
7One-way compression function — In cryptography, a one way compression function is a function that transforms two fixed length inputs to an output of the same size as one of the inputs. The transformation is one way , meaning that it is difficult given a particular output to… …
8Bootstrapping Server Function — A Bootstrapping Server Function (BSF) is an intermediary element in Cellular networks which provides application independent functions for mutual authentication of user equipment and servers unknown to each other and for bootstrapping the… …
9Challenge-Handshake Authentication Protocol — In computing, the Challenge Handshake Authentication Protocol (CHAP) authenticates a user or network host to an authenticating entity. That entity may be, for example, an Internet service provider. CHAP is specified in RFC 1994. CHAP provides… …
10Data Authentication Algorithm — The Data Authentication Algorithm (DAA) is a former U.S. government standard for producing cryptographic message authentication codes. According to the standard, a code produced by the DAA is called a Data Authentication Code (DAC). The algorithm …
