Abstract: A method and a system for correcting cyclic redundancy check (CRC) for a frame with last bytes changed are provided. The method includes acquiring a data frame, calculating a CRC of a modified data frame, and determining a corrected CRC for the data frame based on at least the CRC of the modified data frame and a CRC correction field calculated on the bytes to be replaced at the end of the frame. An altered data frame includes the data frame with a number of last bytes of the data frame replaced with new bytes.
