Embodiment Construction

[0029] figure 1 is a block diagram of a communication hub according to an embodiment of the present invention. Please refer to figure 1 , the communication hub 100 includes a processor 110 , a storage unit 120 , a memory 130 , a remote communication unit 140 and a local communication unit 150 . The processor 110 is coupled to the storage unit 120 , the memory 130 , the remote communication unit 140 and the local communication unit 150 .

[0030] The processor 110 is, for example, a central processing unit (Central Processing Unit, CPU), an image processing unit (Graphic Processing Unit, GPU), a physical processing unit (Physics Processing Unit, PPU), a programmable microprocessor (Microprocessor), an embedded Control chip, digital signal processor (Digital Signal Processor, DSP), application specific integrated circuit (Application Specific Integrated Circuits, ASIC) or other similar devices. The processor 110 is used to execute hardware, firmware and process data in the co...

Abstract

The invention relates to a communication hub and a method for verifying a message among applications thereof. In a start-up process, a processor uses a start-up program to generate a secret key for afirst and second application separately and transmits all the secret keys to the first and second applications, so that each of the applications carries corresponding at least one secret key when performing message transfer. After entering an operating system, when the first application receives a message from the second application, whether the message is valid is verified according to the secretkey carried in the message. When the message is judged to be valid, the first application passes back response information according to the message. When the message is judged to be invalid, the message is neglected or discarded. According to the communication hub, in the start-up process, a corresponding secret key is given to each of the applications, and the secret keys are utilized to performverification during message transfer among the applications, thereby preventing illegal access of malicious programs. In addition, a communication port of each application can be matched for verification, thereby further enhancing security.

Description

technical field [0001] The invention relates to an information verification mechanism, and in particular to an information verification method between a communication hub and its application programs. Background technique [0002] Generally speaking, data in each application program in the operating system is not allowed to be accessed by other application programs. This is to prevent private or confidential data from being accessed by other applications, so that other applications cannot obtain data directly through the shared memory. In order to enable different application programs to access resources and perform coordinated work, an inter-process communication (Inter-Process Communication, IPC) technology is used to transmit data or signals. However, any malicious program can masquerade as a valid application program and use IPC to transmit information to obtain user privacy. [0003] Therefore, a method for verifying information between a communication hub and its app...
