Abstract

The invention provides a trusted boot method and apparatus for a mobile operation system. The method comprises the steps of powering on a system, executing a Boot ROM Code embedded in an SOC by a CPU, and calling a GMB algorithm of a security encryption chip and a measurement reference value pre-stored in the encryption chip to measure whether a Preloader is trusted or not; if the Preloader is trusted, executing a Preloader code, and calling the GMB algorithm of the security encryption chip and the measurement reference value pre-stored in the encryption chip to measure whether a Boot Loader is trusted or not; if the Boot Loader is trusted, executing a Boot Loader code, and calling the GMB algorithm of the security encryption chip and the measurement reference value pre-stored in the encryption chip to measure whether a kernel is trusted or not; if the kernel is trusted, executing the kernel, and calling the GMB algorithm of the security encryption chip and the measurement reference value pre-stored in the encryption chip to measure whether an application framework is trusted or not; and if the application framework is trusted, executing an application framework code, thereby finishing system boot. By adopting the scheme, the boot security of the mobile operation system can be improved.

Description

technical field [0001] The invention relates to the technical field of trusted computing, in particular to a method and device for trusted startup of a mobile operating system. Background technique [0002] With the rapid development of mobile communication technology, smart mobile terminal products are emerging in an endless stream. Various mobile products bring us great convenience and have become a part of our life and work. [0003] However, the development of mobile products is more focused on the improvement of functions and performance, and the development of security is relatively lagging behind. However, with the exposure of various information security issues, security has begun to attract everyone's attention. For the secure boot of mobile products, the current technical means rely more on staged verification instead of doing a secure boot from the moment the product is powered on, and the verification method uses a software encryption algorithm and the verificati...
