Abstract

The invention provides a safety display control method and device. A CPU processor of the safety control module adopts a multi-core architecture; the operation responsible for decryption and display sending is allocated to the exclusive CPU core; the system CPU core cannot decrypt the display data; the exclusive CPU core is used for processing the data of the internet access or the host interfacefor displaying; and the safety control module is isolated from the system CPU core of the system task, if the system CPU core needs to send display, the data is also sent to the exclusive CPU core, sothat a multi-core structure is arranged in the system CPU of the safety control module, the safety function is completed by the exclusive CPU core, and the risk caused by cracking of the system CPU core is avoided.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a method and device for secure display control. Background technique [0002] With the development of information technology, security threats to information system security emerge in an endless stream, and network information security is facing major challenges. As the output device of the computer, the monitor is an important way for human-computer interaction and is an important peripheral hardware in the computer system. People perform corresponding operations on the device through the content displayed on the display. If there is a loophole in the system program that controls the display, hackers will not only be able to obtain the content data being displayed, but they can even manipulate it to display other information to achieve the purpose of deceiving users. Based on this, phishing websites can be forged, and others can access fake banks and e-com...
