Abstract

The invention discloses a device and method for ensuring the security of instructions between heterogeneous systems. The device is connected to various application subsystems, including: a front-end access module connected to various application subsystems, and receiving instruction messages from the application subsystems , according to the pre-defined safety rules, perform security verification on the instruction message, and forward the verified instruction message to the instruction control module; receive the instruction message from the instruction control module and forward it to the application subsystem after security verification; The control module is connected to the front-end access module, receives an instruction message sent by the front-end access module, performs security verification on the instruction message, and sends the instruction message that passes the security verification to the front-end access module. In the present invention, there is no direct instruction processing between subsystems, and the instructions must be distributed after centralized processing, which ensures the safe interaction of instructions between subsystems.

Description

technical field

[0001] The invention relates to the field of system integration, in particular to an instruction security device and implementation method among heterogeneous systems in the field of system integration. Background technique

[0002] With the continuous development of information technology, there are more and more various application information systems, and the integration between systems is becoming more and more complex. Taking the urban emergency linkage system as an example, the subsystems involved include: wired network / call center system, wireless trunking system, video system, large-screen display system, traffic flow monitoring system, computer communication network system, network management monitoring system, The command library system, police reception system, geographic information system, global satellite positioning system, computer-aided dispatching system, mobile command system, chief command system, security system, office automation system,...

Examples

Embodiment Construction

[0023] The device and method in the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] figure 1 It is a schematic diagram of the position of the command safety device during system integration. We can see that various application subsystems such as call center 101, wireless cluster 102, video system 103, large-screen display system 104, and alarm system 105 are all related to the command The control system is connected to transmit instructions through the computer communication network (Ethernet).

[0025] figure 2 It is a composition diagram of the device for ensuring command security between heterogeneous systems of the present invention. The device 200 of the present invention is divided into two parts: a front-end access module 210 and a command control module 220 .

[0026] The main function of the front-end access module 210 is to be responsible for command communication with each application subsystem. At the s...
