Cyclic redundancy check. A cyclic redundancy check ( CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. [1] [2] Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents.
FIREFLY key - (NSA) keys used in an NSA system based on public key cryptography. key encryption key (KEK) - key used to protect MEK keys (or DEK/TEK if MEK is not used). key production key (KPK) -Key used to initialize a keystream generator for the production of other electronically generated keys.
It alerts the client to wait for a final response. The message consists only of the status line and optional header fields, and is terminated by an empty line. As the HTTP/1.0 standard did not define any 1xx status codes, servers must not send a 1xx response to an HTTP/1.0 compliant client except under experimental conditions. 100 Continue
Microsoft saw the need to patch their cryptography subsystem so it would check the status of certificates before trusting them. As a short-term fix, a patch was issued for the relevant Microsoft software (most importantly Windows) specifically listing the two certificates in question as "revoked". Problems with certificate revocation lists

An irreducible code is a cyclic code in which the code, as an ideal is irreducible, i.e. is minimal in , so that its check polynomial is an irreducible polynomial. Examples [ edit ] For example, if A = F 2 {\displaystyle A=\mathbb {F} _{2}} and n = 3 {\displaystyle n=3} , the set of codewords contained in cyclic code generated by ( 1 , 1 , 0 ...
