代码签名

简介

代码签名部件用于支持OpenHarmony的代码签名机制。OpenHarmony使用代码签名提供运行时应用程序的完整性保护,校验应用来源的合法性。

代码签名部件架构图

代码签名部件主要提供如下模块功能:

  • 可信证书管理:将设备证书和本地签名证书写入内核.fs-verity keyring,支持证书链及其合法路径校验。
  • 代码签名使能:在用户态提供代码签名校验的相关接口和逻辑,供应用安装的时候调用,为应用和代码文件使能代码签名。
  • 本地代码签名:在设备侧运行签名服务给本地代码提供签名接口,为AOT生成的机器码文件生成代码签名。
  • 代码属性设置:支持代码所有者标记及校验,提供配置XPM验签地址区接口。
