Embodiment

[0034] The enhanced access module in this example is also used to set the protection level for reading and writing files. The system block diagram is as follows figure 1 .

[0035] The intelligent terminal system in this example includes an intelligent terminal body, an integrity protection module, an enhanced access control module, an encryption protection module and a software security module.

[0036] Wherein, the integrity protection module is used to detect whether the key files in the ROM of the intelligent terminal body are complete through the boot area code before the system is started. The specific method is: a. Obtain the signature content of the key files in the ROM of the intelligent terminal body, and the calculation method thereof For: M=S 官方私钥 (H (key file)), where S refers to the signature algorithm, M refers to the signature content, and H refers to the hash algorithm; b. Calculate H’=S 官方公钥 (M), judge whether H' and H (key file) are the same, if they are t...
