TCB是什么文件，怎么打开

在电脑中突然出现TCB文件，不知怎么来的，

TCB是Trusted Computing Base的简称，指的是计算机内保护装置的总体，包括硬件、固件、软件和负责执行安全策略的组合体。它建立了一个基本的保护环境并提供一个可信计算机系统所要求的附加用户服务。

tcb不是可执行文件,不能打开的!~

the trusted computing base (tcb) is the part of the system that is responsible for enforcing the information security policies of the system. all of the computer’s hardware is included in the tcb, but a person administering the system should be concerned primarily with the software components of the tcb. if you install the trusted computing base option, you enable the trusted path, trusted shell, and system-integrity checking (tcbck command). these features can be enabled only during bos installation
