ARM TrustZone api在哪里？

Question

我在trustzone_security_whitepaper.pdf，第5.5章中介绍了TrustZone API，

>To encourage the development of security solutions ARM have produced a 
>standardized software API, called the TrustZone API (TZAPI), which defines 
>a software interface which client applications running in the rich operating
>environment can use to interact with a security environment.

和5.5.1 API可用性

>"The TrustZone API can be downloaded for free from the ARM website" 

我搜索了arm网站，但未找到TrustZone api列表或手册的条目？

Answer 1

据我所知，TrustZone API（TZAPI）已被弃用 其中一个参考文件是ARM SMC Calling Convention。

如果您寻找特定的Trustzone API，那么它真的取决于您想要构建的内容 如果要构建受信任的应用程序，请查看TEE（可信执行环境）。
