TRUSTED KERNEL STARTING METHOD AND APPARATUS

摘要

A trusted kernel starting method and apparatus are provided. The method includes: starting a security boot module boot loader; invoking the boot loader to measure, according to a first security algorithm, whether a platform configuration register (PCR) partition is trusted; if the PCR partition is trusted, invoking the boot loader to read kernel code into a memory, and invoking the boot loader to measure, according to a first complete algorithm and a kernel code standard measurement value prestored in the PCR partition, whether the kernel code is trusted; initializing, if the kernel code is trusted, the kernel code to trigger an initialized kernel to measure, according to a second complete algorithm, whether the boot loader is trusted; and starting the kernel if the boot loader is trusted. Kernel starting security is improved.
