The invention relates to the technical field of
electronic toll collection (ETC), in particular to a front-mounted ETC
on board unit online publication
system and a front-mounted ETC
on board unit online publication method. The

on board unit, a mobile publication device, a remote
server and an encryptor, wherein the mobile publication device is used for awakening the on board unit, and performing dedicated short range communication (DSRC) with the on board unit by using
publication data acquired in real time from the remote
server and key data calculated by the encryptor through a
wireless communication network such as a third-generation (3G)
wireless communication network; and the remote
server is used for performing publication operation such as initialization,
personalization and tamper activation on the front-mounted on board unit through a
communication channel of the mobile publication device. According to the
system and the method provided by the embodiment of the invention, the
publication data can be acquired from the remote server in real time, the on board unit can be updated in real time, the respective storage of keys for operating the on board unit in each piece of publication equipment is avoided, and the security of a key medium and convenience for a publication service are improved.
