Design and Implementation of Resistance Mechanisms against Malicious Code Attack for Secure SoC

摘要

Although code download can improve the applicable flexibility of the secure SoC, it also brings up new secure threats to the inner sensitive information and resource. In order to resist malicious code attack, the logic design of secure memory management of different levels is presented using software and hardware co-design method, and some access strategies for identification and so on are proposed. combining the hardware logic with the strategies, the secure function of code download and sensitive information protection is performed, and it can resist malicious code attack for the secure SoC effectively.
