Rail transportation ticket-card processing intelligent system and data encryption auditing method

Abstract

The invention discloses a rail transportation ticket-card processing intelligent system, which comprises a sorting center and an automatic ticketing system for a plurality of rail transportation lines. The sorting center comprises a set of service computers, and the automatic ticketing system comprises a set of equipment computers and a ticket-card processing intelligent terminal connected with the equipment computers; and the card processing intelligent terminal is used for processing of ticket transaction flow, issuing of single ticket transaction keys, online authentication of value-stored ticket recharge and generation and verification of transaction logs. The sorting center also comprises an encryption computer which is connected with the ticket-card processing intelligent terminal and is used for receiving an encryption certification request of the ticket-card processing intelligent terminal; and the equipment computers are used for transmitting service commands to the ticket-card processing intelligent terminal and receiving the service command processing result. The modification of the ticket-card processing service is realized through the online update function of the parameters or ticket-card processing programs and the maintenance cost due to the updated card processing programs is reduced. The invention also discloses a data encryption auditing method.

Description

technical field [0001] The invention relates to the field of rail transit systems, in particular to an intelligent rail transit ticket processing system including a rail transit automatic fare collection system (Automatic Fare Collection system, AFC) and a clearing center (ACC, AFC Clearing Center). Background technique [0002] The rail transit ticket processing intelligent system uses a non-contact IC card as the ticket carrier, and records the ticket sales time, amount and other information on the ticket when the ticket is sold; Inbound station and time; when passengers leave the station, if it is a one-way ticket, the exit gate will judge whether to allow the passenger to exit the station and recycle the ticket card according to the amount in the ticket, the entry station and other information, if it is a stored-value ticket, the exit gate will The computer calculates the ride amount based on the information such as the entry station and time in the ticket, and deducts t...

AI Technical Summary

Problems solved by technology

The main defects of the current model are as follows: (1) Ticket processing is the core business processing of the AFC system. Keys, ticket rules and other technical specifications are implemented in the computer of the device according to their respective technical characteristics

Due to differences in understanding of technical standards, business processing is inconsistent, which affects the interconnection and intercommunication between different lines of rail transit

After the system is delivered, the owner formulates different maintenance plans according to the systems of different contractors, and the later maintenance is more difficult

(2) When the ticket processing program is upgraded, it is necessary to upgrade the ticket processing software on various AFC equipment computers, and the line AFC equipment often belongs to different contractors, and different contractors need to modify and test the software, as well as the line network Interconnection and intercommunication test, the transformation project is relatively large

(3) Deployment of the ticket card processing process software on the computer will cause some sensitive data related to the security of the ticket card transaction to also need to be stored on the computer, and the computer and the system are connected by a network, and the relevant content is easy to be stolen

[0004] At the same time, there are certain defects in the security of the current mode of ticket processing. For example, when operating on the MIFARE ONE card, the computer first needs to read the card key from the SAM card (Security Access Module, Security Access Module), and then the computer Use this key to verify the ticket
