Cyclic Redundancy Check: Computation of CRC, Mathematics of CRC, Error detection and correction, Cyclic code, List of hash functions, Parity bit, ... Cksum, Adler- 32, Fletcher's checksum - Softcover
Synopsis
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A cyclic redundancy check (CRC) is a non-secure hash function designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives. A CRC-enabled device calculates a short, fixed-length binary sequence, known as the CRC code or just CRC, for each block of data and sends or stores them both together. When a block is read or received the device repeats the calculation; if the new CRC does not match the one calculated earlier, then the block contains a data error and the device may take corrective action such as rereading or requesting the block be sent again. CRCs are so called because the check (data verification) code is a redundancy (it adds zero information) and the algorithm is based on cyclic codes. The term CRC may refer to the check code or to the function that calculates it, which accepts data streams of any length as input but always outputs a fixed-length code.
