Safe treatment method of network tax-control system

Abstract

The invention discloses a safe processing method for network tax control systems. The method comprises: a network tax controller is used for verifying completeness of a tax control data collecting module through storing a measured value for completeness detection and a verifying code for completeness verifying transmitted by the tax control data collecting module. The invention has two levels of online status monitoring: the network tax controller monitors the data collecting module and the tax control server monitors the network tax controller. Safe data transmission is realized for the taxcontrol server and the network tax controller by means of identification certification and safe communication layer. The safe processing method is carried out in three aspects: part completeness verifying, online status monitoring and safe transmission of tax control data, ensures safety of the network tax control system without changing the processed commercial MIS system, and effectively ensures accuracy of tax control of the whole network tax control system.

Description

technical field [0001] The invention relates to a system security technology, in particular to a security processing method used in a network tax control system. Background technique [0002] At present, with the development of computer and network technology, network systems composed of computers and various hardware devices are more and more widely used, such as e-commerce systems, e-government systems, online banking, network tax control systems, etc. Security is the key to these The prerequisite for the normal operation of the system, especially for the existing commercial MIS system, the security of the network tax control system that controls tax by ticket is more important. The network tax control system is attached to the existing commercial MIS system. The integrity of each component in the tax control process of the network tax control system, the online status security monitoring, and the security of tax control data transmission can achieve the purpose of accurat...

AI Technical Summary

Problems solved by technology

If it is implemented by replacing the hardware part of the commercial cash register, it will not only increase the cost, but also affect the normal use of the existing commercial MIS system, and cannot realize the embedded tax control data collection without changing the existing commercial MIS system module protection

[0011] (2) Since the network tax control system for commercial MIS system is implemented in the local area network, the transmission of tax control data has no confidentiality requirements. If the SSL protocol is used to realize the secure transmission of the network system, it is complicated to implement, and Reduced the efficiency of the entire network tax control system

[0012] (3) Due to the characteristics of the existing stand-alone tax control system in a stand-alone environment, the security processing method it uses cannot be applied to the network tax control system without changing the commercial MIS system
