Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to an ETC password server. Background Technology

[0002] ETC (Electronic Toll Collection) refers to a toll collection method that automatically completes vehicle identification, toll collection, lane equipment control, and toll data processing without stopping the vehicle, using technologies such as radio frequency identification and computers. It is one of the service functions of intelligent transportation systems. The ETC system takes less than two seconds to collect tolls per vehicle, and its toll lane capacity is 5 to 10 times that of manual toll lanes. It is particularly suitable for use on highways or in busy bridge and tunnel environments, improving traffic efficiency, saving manpower and management costs, enabling paperless and cashless toll collection, and saving infrastructure costs. Based on these advantages, the application of the ETC system has been actively promoted in my country. As of the end of September 2021, the average usage rate of ETC across the entire network exceeded 66%, significantly improving the traffic efficiency of the highway network and significantly enhancing logistics cost reduction and efficiency.

[0003] The ETC system consists of a front-end system and a back-end database system. The front-end system includes the vehicle control system, RSE (Roadside Equipment), OBE (On-Board Equipment), and ICC (Integrated Circuit Card). The back-end database system is the core data management module supporting the operation of ETC services. Its core functions include data storage and management, transaction processing and clearing settlement, and data security. Among them, the ETC cryptographic server is a crucial piece of equipment in the ETC back-end database system.

[0004] With the rapid development of localization in recent years and the requirement to improve network security protection capabilities, the highway toll collection and settlement system has been included in the national information security special plan, and various domestic ETC devices applied to highway entrances have emerged accordingly.
