🌘 使用 GDB 辨識 Arm Cortex-M 的當前安全狀態
➤ 透過堆疊指標數值比對，快速掌握 TrustZone 運行切換

在嵌入式系統開發中，調試具備 TrustZone（Armv8-M 安全擴充功能）的處理器（如 Arm Cortex-M33）常面臨一項挑戰：如何快速判斷處理器目前正處於「安全（Secure）」還是「非安全（Non-Secure）」狀態。開發者 Daniel Mangum 提供了一個簡潔高效的方案。由於處理器在不同安全狀態下會使用各自獨立的堆疊指標（Stack Pointer, SP），我們只需透過 GDB 同時讀取當前的 SP 以及各個堆疊指標變體（MSP_S, MSP_NS 等），並進行數值比對，就能即時揭示處理器的運行環境。這種方法在處理如 Zephyr RTOS 等複雜的多執行緒系統時，能顯著提升排錯效率。

If you need Secure Boot for STM32MP157 , we got you covered with STMP157-SOM-512-SB and STMP157-OLinuXino-LIME2H-SB now featuring STM32MP157FAA1 extended temperature range -20+105C running at 800Mhz and secure boot https://olimex.wordpress.com/2025/07/29/we-can-now-offer-version-of-smt32mp157-boards-with-secure-boot-and-aes256/ #stm32mp157 #secure #boot #trustzone

At BlackAlps, Marcel Busch and Philip Mao show how forgetting to check input types in the trusted apps of TrustZone leads to memory read/write.

A few years old but still an interesting blog post showing how to attack Mobile Trusted Execution Environments (ARM TrustZone) to extract biometric data

Anyone here who has experience with bare-metal programming TrustZone-M applications for Nordic platforms? I have problems configuring my NSC region and I can't figure out what's wrong 😫
(please boost, I need this)

Update: Found the problem, it works now!

Intro to embedded systems security and TrustZone

#iot #trustzone #cybersecurity

Trusted computing got a new coat of paint. Now it's called "confidential computing", and it's totally not about who controls the machine, not at all.

A talk at #rustlab2023 triggered me, so I had to rant about it on my blog. Sorry.

Digitalized some of my old notes...

Here is my documentation of which mode switches are possible in #arm #trustzone

Hope this helps someone :blobsmile:​ (wish I had that back in the days... yep, each of these arrows was a "flash SD-card, boot circuit board, check if LED lights up, repeat")

I was looking at arm microcontrollers for a project at work recently. This is not something I have done in a while. Some of the newer ones have features like page protection and secure enclave support that I’ve never seen at that level before. Seems like progress. #microcontroller #trustzone #iot

@ellenor I don’t need high performance so I use ~15 y.o. hardware that pre-dates the spy chips. But still my hardware was not targeted by #coreboot / #libreboot, so my firmware is non-free. I also have some newer hardware that I pulled out of dumpsters (thus did not contribute to the intel M.E./ AMD #trustzone spy chip market), which I just use for occasional experiments.

very funny, when you want to do surveillance, name your solution so that it contains word #trust in it.

yes, because the most widespread #os for #pc is #minix, if you did not know that.

it seems that my #pinebook with #rockchip chipset is pretty safe:
it has an #M0 that does power management, and there is #EL3 (exception level 3), which some people see in the same light. those are auditable from userspace and are probably safe.
