Problems solved by technology

[0018] (1), cumbersome operation
The information of the electronic label is imported through an import card, and an activation card is also required, which is cumbersome to operate and takes a long time
[0019] (2), insufficient security
Since the electronic tag does not contain a security module, the information file of the imported card cannot be verified. The information file can only be read freely, and it is easy for someone to forge an imported card and import illegal information into the electronic tag.

Embodiment Construction

[0035] The issuing method of the ETC electronic label in the present invention includes a host computer, a fixed equipment RSU and an electronic label OBU. During the issuance process, a wireless transaction instruction interface is added between the fixed equipment RSU and the electronic label OBU for electronic The tag OBU writes or reads information, and completes the issuing operation by wirelessly transmitting data, instead of importing the card as the transmission medium. A security module or a software or hardware module with a certain level of security is added to the electronic label OBU, which is used for mutual authentication and data encryption and decryption with the fixed equipment RSU during data communication.

[0036] A complete electronic label issuance process consists of two sub-processes, namely primary issuance and secondary issuance. Among them, a release refers to creating a file system in a blank electronic label OBU, writing the file access key, and w...
