Description

technical field [0001] The invention relates to the technical field of security chips, in particular to an embedded security module system. Background technique [0002] With the development of electronic science and computer technology, more and more embedded devices have entered people's lives, and gradually play an important role in system automatic control and data storage in many fields. At the same time, more and more applications and more convenient network access make embedded platforms face more and more security challenges. Embedded systems have strict resource constraints in terms of computing power, memory, and energy. Using virus scanning and anti-intrusion software on general-purpose computers to defend against security attacks will result in reduced performance and increased power consumption. Therefore, the security problems of embedded systems are more challenging than those of general-purpose systems. [0003] The ultimate goal of security attacks is to ...
