Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Such as figure 1 Shown is a block diagram of the electronic label system of the present invention. This embodiment provides an electronic tag 1 , an antenna 3 and a read / write device 5 . The data packet 10 of the electronic label 1 is divided into a guide area and a data area. The guide area is composed of 8 bytes and a total of 64 bits. No data is stored. The data area includes domain number byte, data length byte, data part and BCC check code. The data packet 10 of the electronic tag 1 is encrypted by DES, and a ciphertext of the data packet of equal length is generated and stored in the electronic tag 1 .

[0016] In this embodiment, the DES algorithm performs encryption and decryption operations on data blocks of fixed size (64 bits). For those data blocks that are less than 64 bits, it is necessary to use a padding mechanism to ...

Abstract

The invention discloses an electronic label system comprising an electronic label, a read-write device and an antenna, wherein a data packet of the electronic label is divided into a guiding region and a data region, wherein the guiding region consists of eight bytes amounting to 64 bits, when the data bit of the guiding region is 1, a data field is provided with storage data, when the data bit is 0, the data field is not stored with data; the data region comprises a field number byte, a data length byte, a data portion and a BCC check code; and the data packet of the electronic label is encrypted through a DES (Data Encryption Standard) to generate data packet cryptographic texts with an equal length to be stored into the electronic label. The invention also discloses a compression and encryption method of the electronic label. The electronic label system and the compression and encryption method thereof save the storage space of the electronic label and realize safe reading of the electronic label data.

Description

【Technical field】 [0001] The invention relates to an electronic label, especially an electronic label system and its compression and encryption method. 【Background technique】 [0002] The spatial coupling of the radio frequency signal is realized through the coupling element between the electronic tag and the reading and writing device, and in the coupling channel, energy transmission and data exchange are realized according to the timing relationship. The most basic electronic tag system consists of three parts: electronic tags, read-write devices and antennas. The electronic tag has a unique electronic code, has user-writable storage space, and is attached to the object to identify the target object. [0003] At present, the storage space of electronic tags is relatively limited, and the non-compact storage scheme not only causes the waste of scarce storage space, but also causes the storage capacity of electronic tags to fail to meet the needs of applications; in additio...
