Abstract

The invention provides a radio frequency identification anti-fake verification method for leader personnel dossier management, and relates to information technologies and technologies of internet of things. The radio frequency identification TID number meeting the ISO/IEC18000-6 standard is the unencrypted globally unique 8-bit plain code generated in the production process of a radio frequency identification chip manufacturer and can be read by all the radio frequency users, and the anti-fake function cannot be achieved. As the radio frequency identification of the leader personnel dossier management, the radio frequency identification only can be identified through one anti-fake method, and the falsely users can be prevented to copy the anti-fake information and make the identification. According to the radio frequency identification anti-fake verification method, the radio frequency identification TID number is encrypted through a DES algorithm, the cryptograph is made to serve as the anti-fake information to be written in the leader personnel dossier radio frequency identification user region, the information is encrypted through the DES algorithm when anti-fake verification is conducted, the plaintexts are compared with the TID of the radio frequency identification, and the authenticity of the radio frequency identification can be verified.

Description

A kind of mark of the radio-frequency (RF) identification for personnel file management anti-counterfeit authentication method

One, technical field

Patent of the present invention relates to information technology, technology of Internet of things.

Two, background technology

REID is a kind of wireless communication technology, and the radio-frequency (RF) identification that this technology utilizes radio signals identification to be attached on target object identifies, to obtain the relevant information of target object.Relative to conventional identification techniques such as bar code, image recognition and bio-identification, REID has little, the advantage such as information capacity is large, antiforge function is strong affected by environment.The conventional frequency range of passive radio frequency identification technique conventional at present comprises low frequency (125kHz ~ 134.2kHz), high frequency (13.56MHz) and hyperfrequency (840MHz ~ 960MHz).Relative to low frequency and high-frequency radio frequency recognition technology, super high frequency radio frequency recognition technology has again the advantages such as reading speed is fast, reading distance, many tag reading capabilities are strong.

Along with constantly perfect, the equipment of super high frequency radio frequency recognition technology and the continuous decline of mark cost, be applied in fields such as entrance guard management, taking care of books, asset management, traffic administrations.As personnel file management radio frequency identification except needs can by fast, batch also needs to have the characteristics such as false proof, anti-copying except reading.

Three, summary of the invention

No. TID, super high frequency radio frequency identification marking is the globally unique plain code of 8 byte being identified the not encrypted that chip manufacturer generates in process of production by radio-frequency (RF) identification, and the user of radio frequency identification can read, and can not play false proof effect.As personnel file management radio-frequency (RF) identification mark, not only require to adopt a kind of method for anti-counterfeit that this radio frequency identification can only encrypted person be identified, but also will prevent from emitting user to copy this enciphered message and forge cadre' s record radio-frequency (RF) identification mark.

Patent of the present invention has the characteristic of anti-fake certificate in personnel file management, and concrete methods of realizing is as follows in actual applications:

1, cadre' s record radio-frequency (RF) identification mark anti-counterfeiting information write

Read No. TID that frequently penetrates identification marking by radio frequency identification read-write equipment, adopt No. TID, this radio frequency identification of DES algorithm for encryption, obtain ciphertext, then by radio frequency identification read-write equipment, ciphertext is write this radio frequency identification user area.

2, the anti-counterfeiting authentication method of cadre' s record radio frequency identification

Read by radio frequency identification marking recognition write device and frequently penetrate identification marking and be stored in anti-counterfeiting information ciphertext in user area, adopt DES algorithm to be decrypted the ciphertext read, obtain expressly.Read this radio frequency identification again by radio frequency identification marking recognition write device No. TID, finally No. TID, this radio frequency identification read is compared with by deciphering the plaintext obtained, if consistent, show that this radio-frequency (RF) identification mark is real cadre' s record radio frequency identification, complete fake certification.

DES algorithm is a kind of block encryption symmetry algorithm using secret key encryption of American I BM company development in 1972, in November, 1976 is confirmed as u.s. federal standard, and issue as FIPS PUB46 on January 15th, 1977, it was 1988 (being changed to FIPS-46-1), 1993 (being changed to FIPS-46-2), widespread comes in the world subsequently.

The general principle of DES work is: get 56 long keys, expressly divides into groups by 64, the method that the key step-by-step of the plaintext group after grouping and 56 substitutes or exchanges is formed method encryption or the deciphering of ciphertext group.Its suction parameter has three: key, data, mode.Key is the key that encrypting and decrypting uses, and data is the data of encrypting and decrypting, and mode is its mode of operation.When pattern is encryption mode, expressly divide into groups according to 64, form expressly group, key is used for data encryption, and when pattern is decryption mode, key is used for data deciphering.

This cryptographic algorithm mainly contains following characteristics:

(1) provide high-quality data protection, prevent the unwarranted leakage of data and unperceived amendment;

(2) have quite high complexity, be convenient to again understand and grasp simultaneously, the expense decoded is exceeded can obtainable interests;

(3) fail safe of DES cryptographic system do not rely on algorithm maintain secrecy, its fail safe only by encryption key maintain secrecy based on;

(4) realize economy, effective operation, and be applicable to the false proof application of cadre' s record radio frequency identification.

Five, embodiment

(1) reading No. TID of some radio frequency identifications by radio frequency identification read-write equipment is: E280110520005443 (hexadecimal).

(2) adopt No. TID, DES algorithm radio frequency identification marking to be encrypted, encryption key is " 123456 ", obtains ciphertext to be: A615BBD23A66ED0E0FBAF3818B895863 (hexadecimal).

(3) by radio frequency identification read-write equipment, this ciphertext is write radio frequency identification user area.

2, cadre' s record radio-frequency (RF) identification mark fake certification

(1) read some cadre' s record cadre' s record radio-frequency (RF) identification by radio frequency identification read-write equipment and identify the ciphertext be stored in user area: A615BBD23A66ED0E0FBAF3818B895863 (hexadecimal).

(2) adopt DES algorithm to be decrypted the ciphertext read, decruption key is " 123456 ", obtains to be expressly: E280110520005443 (hexadecimal).

(3) reading No. TID of this radio frequency identification by radio frequency identification read-write equipment is: E280110520005443 (hexadecimal).
