Cyclic Redundancy Check - an overview ScienceDirect Topics

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. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. On … See more CRCs are based on the theory of cyclic error-correcting codes. The use of systematic cyclic codes, which encode messages by adding a fixed-length check value, for the purpose of error detection in communication … See more CRCs are specifically designed to protect against common types of errors on communication channels, where they can provide quick and reasonable assurance of the See more Mathematical analysis of this division-like process reveals how to select a divisor that guarantees good error-detection properties. In this analysis, the digits of the bit strings are taken as the coefficients of a polynomial in some variable x—coefficients that … See more CRCs in proprietary protocols might be obfuscated by using a non-trivial initial value and a final XOR, but these techniques do not add cryptographic strength to the algorithm and can be reverse engineered using straightforward methods. See more A CRC-enabled device calculates a short, fixed-length binary sequence, known as the check value or CRC, for each block of data to be sent or stored and appends it to the data, forming a codeword. When a codeword is received or read, the device either … See more To compute an n-bit binary CRC, line the bits representing the input in a row, and position the (n + 1)-bit pattern representing the CRC's divisor … See more The concept of the CRC as an error-detecting code gets complicated when an implementer or standards committee uses it to design a practical system. Here are some of the complications: • Sometimes an implementation prefixes a fixed bit pattern to … See more WebDec 27, 2024 · Cyclic redundancy check (CRC) is a common data transmission error detection technique commonly used in the data communication field. The transmit end calculates a check code for the data in a data frame based on a certain algorithm, appends the check code to the data frame, and sends the data frame to the receive end. knightshade ucf
