Graphic engine authentication detection method and system applied to embedded terminal

Abstract

The invention relates to a graphic engine authentication detection method and system applied to an embedded terminal. The method comprises the following steps: encrypting and solidifying authentication key information in an encryption chip; reading and decrypting the encrypted and solidified authentication key information in the encryption chip, analyzing the authentication key information to obtain a terminal ID and authentication data, granting a corresponding graphic engine system permission to the current terminal according to the authentication data, and marking the successfully authorized terminal; when the authentication is abnormal again, whether the terminal enters a super mode or not is judged according to a pre-marking result of the current terminal, and the super mode is that the graphic engine works normally and the authentication is reminded to be abnormal. According to the method, the detection of the authentication abnormity of the graphic engine software is effectively realized, the safety is good, and the loss caused by the fact that the software cannot be used when the environment such as hardware abnormally suddenly occurs is avoided.

Description

technical field [0001] The invention relates to the technical field of embedded terminals, in particular to a graphics engine authentication detection method and system applied to embedded terminals. Background technique [0002] In order to ensure the security of the graphics engine, when the graphics engine is rendered, the graphics engine authentication will be performed. Through the authentication, the user can only obtain the graphics engine within the scope of his own authority to use the rendering, and the graphics engine is a software product and cannot be effectively implemented. Single-unit authentication, especially in the field of liquid crystal instruments, because the liquid crystal instrument itself has high security requirements and extremely high immediacy, it is necessary to propose a graphics engine authentication anomaly detection method and system applied to embedded terminal products to ensure safe Efficiently implement individual authentication and aut...
