Embodiment Construction

[0012] according to figure 1 , the radio frequency electronic tag is composed of a radio frequency antenna 1, a processor 2, a read-only memory 3 and a read-only memory 4, wherein the UID code 1234 is solidified in the read-only memory, and the encrypted data is obtained by logical operation such as multiplying the UID code by 2 2468, and then write the encrypted data into the readable and writable user memory 4. Read the encrypted data 2468 in the readable and writable user memory 4 of the radio frequency electronic tag through the radio frequency antenna 1 and the processor 2 by using a dedicated reader-writer, and perform a logical inverse operation on this data, such as dividing by 2, to obtain a theoretical UID value 1234, then compare this value with the UID code in the read-only memory 3, and judge the uniqueness of the tag according to whether the two values ​​are the same or not.

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...
