Abstract

The invention discloses a TrustZone-based programming method, terminal equipment and a computer readable storage medium, the TrustZone-based programming method is applied to the terminal equipment, and the terminal equipment comprises a security extension chip with a TrustZone technology. The TrustZone-based programming method comprises the following steps: dividing a storage area of the terminalequipment into a safe area and a non-safe area; dividing the security area into a Bootloader area, an APP security area and a security data storage area, and dividing the non-security area into an APPnon-security area and a non-security data storage area; and controlling the interaction between the APP security area and the APP non-security area. According to the invention, the security of the terminal equipment can be improved, and the programming efficiency of the terminal equipment is improved.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a programming method based on TrustZone, a terminal device and a computer-readable storage medium. Background technique [0002] With the rapid development of science and technology, the application scenarios of IOT (Internet of Things, Internet of Things) are becoming more and more extensive, making more and more terminal devices capable of networking. However, there will be many security threats to the terminal equipment networking. Among them, for the terminal equipment, the terminal equipment needs to upload data to the cloud server. If the terminal equipment has security threats, the uploaded data will be unsafe, resulting in Data has no value, even negative value. Therefore, ensuring the security of terminal equipment is the basis of IOT security. [0003] Usually, an additional security encryption protection chip is added in the terminal equipment to ensure the sec...
