METHOD FOR COMPUTING CRC OF MESSAGE

摘要

PROBLEM TO BE SOLVED: To provide a CRC computation technology for computing CRCs of sub-messages regardless of the order of arrival. SOLUTION: In this method of generating a CRC for a composite sub-message based on a CRC generating polynomial having at least two factors, the composite sub-message includes sub-message data and a number (n) of trailing zeros. The method includes generating a first remainder based on the sub-message data and a first factor of the CRC generating polynomial. A second remainder is generated based on the sub-message data and a second factor of the CRC generating polynomial. The CRC for the composite sub-message is generated based on adjusted versions of the first and the second remainders. COPYRIGHT: (C)2005,JPO&NCIPI
