41Correlation immunity — In mathematics, the correlation immunity of a Boolean function is a measure of the degree to which its outputs are uncorrelated with some subset of its inputs. Specifically, a Boolean function is said to be correlation immune of order m if every… …
42NESSIE — For other uses, see Nessie (disambiguation). NESSIE (New European Schemes for Signatures, Integrity and Encryption) was a European research project funded from 2000–2003 to identify secure cryptographic primitives. The project was comparable to… …
43N-Hash — In cryptography, N Hash is a cryptographic hash function based on the FEAL round function, and is now considered insecure. It was proposed in 1990 by Miyaguchi et al.; weaknesses were published the following year. N Hash has a 128 bit hash size.… …
44OCB mode — (Offset Codebook Mode) is a mode of operation for cryptographic block ciphers. Contents 1 Encryption and authentication 2 Performance 3 Patents 4 See also …
45crypt (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… …
46Message 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… …
47One-key MAC — OMAC (One key MAC) is a message authentication code constructed from a block cipher much like the PMAC algorithm. Officially there are two OMAC algorithms (OMAC1 and OMAC2) which are both essentially the same except for a small tweak. OMAC1 is… …
48Data 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 …
49CMAC — This article is about the cyptographic construction. For other uses, see CMAC (disambiguation). In cryptography, CMAC (Cipher based MAC)[1] is a block cipher based message authentication code algorithm. It may be used to provide assurance of the… …
