Abstract
A method and an apparatus for calculating and checking the Frame Check Sequence (FCS) of a message comprising a sequence of data bytes. A Cyclic Redundancy Code (CRC) is used to generate the FCS at one end and check the message at the other end. For each new byte of the sequence of data bytes, the current FCS, which is a vector of the Galois Field is multiplied by .alpha..sup.8, another vector of the Galois Field.
