Abstract

The invention discloses a terminal authentication information generation method and system based on a national cryptographic algorithm. The method comprises the following steps: reading and decryptinga serial number from hardware fingerprint information; reading and decrypting the verification information from the hardware fingerprint information; reading and decrypting the data segment data fromthe hardware fingerprint information; calculating a check value of the data segment and verifying, verifying whether the calculated check value is consistent with a stored check value or not, if so,entering the next step, and if not, writing error information into a file, and ending; decrypting the data segment, and extracting the serial number, the hardware fingerprint information, the information generation time and the CPU information from the file; performing data consistency verification, whereinif the calculated value is consistent with the stored value, verification succeeds, the nextstep is executed, and if not, error information is written into the file, and the process is ended; generating a random number; and generating data segment information based on the random number andthe file check value, writing the information segment and the data segment information into the file, and ending.
