GB/T 30847.2-2014

GB/T 30847.2-2014 specifies the trust chain model and measurement methods for trusted computing platforms, defining how to establish, propagate, and verify trust from the system boot process through the operating system to applications. It is applied in the design and evaluation of trusted computing systems, particularly in security-critical environments such as government, finance, and telecommunications, where verifying the integrity and trustworthiness of software and hardware components is essential. This standard supports engineers in implementing and assessing trust chain mechanisms to ensure that only authorized and unmodified code executes during system startup and operation.
