## 简介<a name="section469617221261"></a>

itrustee\_ree\_lite组件提供了一套用于和华为自研TEEOS交互的富运行环境（REE）接口组件，包括驱动（tzdriver）、libteec（应用接口库）、teecd（agent服务），其中libteec满足Globalplatform 标准，可提供CA（ClientApp）标准的访问接口。

## 架构<a name="section15884114210197"></a>

itrustee\_ree\_lite组件结构：

![](figures/zh-cn_image_0000001078211160.png)

-   tzdriver：驱动用于ree/tee切换、通讯，提供应用层访问的设备节点。

-   libteec: 提供CA标准GP接口，用于访问设备节点、建立与TEE的通讯会话。

-   teecd：提供agent（代理服务），帮助TEEOS实现文件操作等代理服务。
