Apparatus and method for guaranteeing instruction safety between heterogeneous systems

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,...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a device and method for ensuring the safety of instructions between heterogeneous systems, and solve the problem that the instructions in the prior art do not have security, and the overall system cannot be effectively controlled, which may cause single-point paralysis, or even The problem of bringing about the paralysis of the whole system
