The simplest checksum algorithm is the so-called longitudinal parity check, which breaks the data into "words" with a fixed number n of bits, and then computes the exclusive or (XOR) of all those words. The result is appended to the message as an extra word. In simpler terms, this means adding a bit to the end of the word to guarantee that there is an even number of '1's. To check the integrity of a message, the receiver computes the exclusive or of all its words, including the che… WebJul 16, 2024 · At the Sender side, the data is divided into equal subunits of n bit length by the checksum generator.
