Embedded terminal dependable starting method based on mobile dependable computing module

Abstract

The invention discloses an embedded terminal dependable starting method based on a mobile dependable computing module. Segmentation is carried out on a starting procedure, measurement is carried out on partial content of the starting procedure, although the safety is reduced to some extent, the starting speed is improved greatly, and the defect that the computing capability of embedded type equipment is limited is compensated effectively. After a system is started, measurement of the remaining part is carried out, the computing capability is no longer the pure embedded type equipment, it is ensured that all the verification can be completed in a short time, and safe operation of the embedded terminal is effectively ensured due to the verification of all content as a whole.

Description

technical field [0001] The invention relates to a trusted starting method of an embedded terminal based on a mobile trusted computing module. Background technique [0002] With the development of Internet of Things technology, the intelligentization of embedded terminal devices (hereinafter referred to as terminal devices) has brought great fun and convenience to the lives of the public. Intelligent identification, positioning, tracking, monitoring and management have become the It is a very common function, but the security problems of terminal equipment are also becoming more and more prominent. Hacking attacks and the proliferation of viruses make the security problems of embedded systems particularly serious. [0003] At present, most information security technologies only rely on the combination of strong cryptographic algorithms and keys to ensure the safe operation of the system, but this pure software mechanism is not absolutely safe, and many users' improper operati...

Problems solved by technology

In addition, the system backup program is generally stored in an external memory, the system backup program is particularly easy to be tampered with and destroyed, and the availability of trusted boot cannot be guaranteed

Existing trusted systems do not have a trusted computing module and an authentication process for terminal devices, and are no longer suitable for the trusted boot process of embedded terminals with mobile trusted computing modules

In addition, the existing embedded trusted boot design does not protect and manage the system backup. Once the backup is maliciously destroyed, the embedded terminal device will not be able to be used normally, and the stability is poor.

Finally, existing technologies are slow to start due to limited embedded terminal resources
