I am a man in flip-flops, a long-term automotive electronics engineer in the magic city. As usual, I will share a piece of text I like to avoid becoming an engineer with high knowledge but low culture: After taking a shower on the weekend and changing into a new outfit, I went out but didn’t … Read more
Detailed Explanation of Fault Injection (Part 1) Bypassing Secure Boot One of the security measures that can be compromised through fault injection attacks is secure boot. This will be illustrated using the ESP32 v1 as an example. First, configure a secure boot environment. After installing the ESP SDK, set up a reprogrammable bootloader in case … Read more
Preview PreviewIn the coming weeks, we will spend several weeks or even a couple of months discussing the differences in privilege modes, secure boot, and sleep/wake strategies between the two CPU architectures: ARMv8-A and RISC-V. RISC-V
Hello everyone, I am the Intelligence Guy~When you are debugging a development board late at night and your fingers habitually type <span>printenv</span>, have you ever wondered: As the gatekeeper of the hardware world, why does U-Boot lack even basic password protection? This is not an oversight by developers, but a carefully considered design choice. Today, … Read more
Introduction The #SecureBoot functionality of Arm processors effectively prevents unauthorized or maliciously modified firmware from running on devices. The Secure Boot system uses the keys burned into the processor to verify the Bootloader at startup, which in turn verifies the kernel FIT image, and the kernel continues to validate the rootfs’s integrity. This step-by-step verification … Read more
