发明名称 METHOD FOR IMPROVED SECURITY OF CRC ENCRYPTION SYSTEM
摘要 <p>The digital information is encrypted by first performing a preselected number of CRC iterations or partial convolutions by multiplication with a mask in the Galois Field. Before the CRC operation is completed, the intermediate resultant is subjected to an Integer Ring operation, such as addition, which injects a nonlinearity over the Galois Field due to possible arithmetic carry operations. After the Integer Ring operation, the Galois Field CRC process is continued to completion. The result is an encrypted value which is not readily decrypted by Galois Field techniques.</p>
