ARM的TrustZone发展 [英] ARM TrustZone development

问题描述

我想知道如果任何人有在那里你可以利用ARM的TrustZone上开发板的信息吗？我有一个采用TI公司的OMAP3530与Cortex-A8处理器的BeagleBoard的XM支持信任区域，但是TI证实，他们已经禁用主板上的功能，因为它是一个通用的设备。

I am wondering if anyone have any information on development boards where you can utilize ARM TrustZone? I have the BeagleBoard XM which uses TI's OMAP3530 with Cortex-A8 processor that supports trust zone, however TI confirmed that they have disabled the function on the board as it is a general purpose device.

进一步研究拉去它采用OMAP4430熊猫板，但没有来自TI的反应和在互联网上的信息非常少。你如何学习如何使用信任区？

Further research got me to the panda board which uses OMAP4430 but there is no response from TI and very little information on the internet. How do you learn how to use trust zone?

推荐答案

据我所知，你可以得到所有的OMAP处理器现成的，保质期是GP设备，即在禁用的TrustZone功能（否则他们'重新生产设备，如关闭的，现成的手机，为此，你没有得到的键）处理器。这种情况是与其他的SoC厂商相似。除了ARM的有限的出版物（只覆盖了常见的ARM特点，无论如何，而不是特定芯片的功能，如内存管理的细节，启动和加载信任的code），约了TrustZone功能的所有文档附带保密协议。这是一个遗憾，因为它precludes这些安全功能，或者通过利用开源软件的独立分析。

As far as I know, all the OMAP processors you can get off-the-shelf are GP devices, i.e. with the TrustZone functions disabled (or else they're processors in production devices such as off-the-shelf mobile phones, for which you don't get the keys). The situation is similar with other SoC manufacturers. Apart from ARM's limited publications (which only cover the common ARM features anyway, and not the chip-specific features such as memory management details, booting and loading trusted code), all documentation about TrustZone features comes under NDA. This is a pity because it precludes independent analysis of these security features or leverage by open-source software.

我怕，如果你想为一个的TrustZone器件编程，你必须联系TI或他们的竞争对手之一的重presentative，让他们相信你的应用程序，他们希望发生的事情，并获得HS设备，密钥签署code为您的开发板和文档没有它，你将有一个非常困难的时期。

I'm afraid that if you want to program for a TrustZone device, you'll have to contact a representative of TI or one of their competitors, convince them that your application is something they want to happen, and obtain HS devices, the keys to sign code for your development boards, and the documentation without which you'll have a very hard time.
