Abstract: A method and a device for preventing access to an administrative privilege are provided. The method includes acquiring a flash memory identifier from a flash memory, starting kernel loading, decoding an encrypted administrative privilege granting code using the flash memory identifier, and completing booting when the decoding succeeds. According to an embodiment of the present disclosure, the code for accessing the administrative privilege is encrypted using the identifier of the flash memory so that the unique password code can be loaded for each device, thereby enhancing the system security.

Abstract translation: 提供了一种防止访问管理权限的方法和设备。 该方法包括从闪速存储器获取闪存标识符，启动内核加载，使用闪存标识符对加密的管理权限授权代码进行解码，以及在解码成功时完成启动。 根据本公开的实施例，使用闪存的标识符来加密用于访问管理特权的代码，使得可以为每个设备加载唯一的密码代码，从而增强系统的安全性。
