RF electronic label data encryption anti-counterfeit method

Abstract

The encryption anti-counterfeit method for RF electron label data, it reads UID incrimination code in ROM of radio frequency electron label, new data come into being through logic operation, and it is written in erasable memory. The UID code is only and unchangeable, the coding data is written in erasable memory of label through logic coding operation, the erasable memory and unchangeable UID has a conventional logic relation. Althrough the illegal users can read and write coding data, they can't change the UID code of label.

Description

Technical field: [0001] The invention provides a radio frequency electronic tag data encryption anti-counterfeiting method, which belongs to electronic anti-counterfeiting [0002] technology field. Background technique: [0003] At present, the data format of the radio frequency electronic tag is the data structure of the user data area (readable and writable) and the unique identification code UID (readable and unwritable). When used in the field of encryption and anti-counterfeiting technology, the following two methods are generally used: [0004] Direct identification: Write specific data in the user data area, and then use a special reading device to compare the read data with the original data to identify the authenticity. [0005] Encrypted identification: On the basis of the above method, the encrypted data generated after the specific data is logically encrypted is written into the user data area, and then read with a special device, and decrypted and compared wit...

Problems solved by technology

[0006] No matter which method is used to encrypt, illegal users can read their data through the reading device, and then rewrite an illegal radio frequency electronic tag, destroying the uniqueness of the tag
