    • Normally, at the time of manufacturing, security may be provided to a device being manufactured through the loading of an operating system that has been cryptographically signed. The present application discloses a “factory mode” for the device. The “factory mode” allows the device to execute untrusted operating system code, such as unsigned operating system code and operating system code that has been signed, but the certificate authority is not trusted. To support execution of untrusted operating system code in a secure manner, the device may be adapted to prevent data of predetermined type from being loaded on the device while the device is in the “factory mode”. In contrast to the “factory mode”, the secure mode of the device is referred to herein as a “product mode”. There develops a need to manage, in a secure manner, transitions between the “product mode” and the “factory mode”.
    • 通常,在制造时,可以通过加密已被加密签名的操作系统来为正在制造的设备提供安全性。 本申请公开了该设备的“工厂模式”。 “工厂模式”允许设备执行不受信任的操作系统代码,例如未签名的操作系统代码和已签名的操作系统代码,但证书颁发机构不受信任。 为了以安全的方式支持不可信操作系统代码的执行,该设备可以适于防止在设备处于“工厂模式”时预定类型的数据被加载到设备上。 与“工厂模式”相反,设备的安全模式在这里被称为“产品模式”。 需要以安全的方式管理“产品模式”和“工厂模式”之间的过渡。
