SECURE BOOT APPARATUS AND METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18507879 titled 'SECURE BOOT APPARATUS AND METHOD
Simplified Explanation
The secure boot apparatus and method described in the patent application involve using a control circuit to obtain boot code from a nonvolatile memory and verify it using a root of trust. This allows for the verification of boot code even without a built-in root of trust in the processor, reducing dependency on processor performance. Additionally, the use of a non-programmable circuit coupled to the control circuit and nonvolatile memory through different interfaces enhances application flexibility and reduces interface protocol type requirements.

Original Abstract Submitted
This application provides a secure boot apparatus and method. A control circuit in the secure boot apparatus can obtain boot code in a nonvolatile memory by using a non-programmable circuit, and verify the boot code by using a root of trust. In this way, even if the root of trust is not built in a processor, the verification on the boot code can be implemented by using the control circuit. This effectively reduces dependency of a secure boot process on processor performance. In addition, because the non-programmable circuit can be respectively coupled to the control circuit and the nonvolatile memory through two interfaces of different types, a requirement for the secure boot process on an interface protocol type of the control circuit is reduced, and application flexibility of a secure boot solution is improved.
