WebHW redundancy: overview • passive redundancy techniques – fault masking • active redundancy techniques – detection, localisation, containment, recovery • hybrid redundancy techniques – static + dynamic – fault masking + reconfiguration p. 8 - Design of Fault Tolerant Systems - Elena Dubrova, ESDlab output Passive HW redundancy 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 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 … 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 … See more CRCs are specifically designed to protect against common types of errors on communication channels, where they can provide quick and … See more Mathematical analysis of this division-like process reveals how to select a divisor that guarantees good error-detection properties. In this … 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.
