新款HP笔记本bios设置中 SecureBoot配置干什么用的

[三水木工]

进入bios---高级---引导选项---“SecureBoot配置”， 有两个可选项第一个：“安全引导”，第二个：清除“SecureBoot”秘钥，请问这个有什么作用？
因为和密码有关系，担心机器被锁未敢擅自实验，请有经验的朋友解释下！

和密码没有关系，secureboot是UEFI的一种功能，针对windows 8上系统的，属于一种系统启动前的保护，比如阻止未经签名的bootloader，或者盗版cd启动等。

Secure Boot Configuration is a new feature of the Unified Extensible Firmware Interface (UEFI) in BIOS 8 that helps a computer resist attacks and infection from malware. When your computer was manufactured, UEFI created a list of keys that identify trusted hardware, firmware, and operating system loader code. It also created a list of keys to identify known malware. When Secure Boot is enabled, the computer blocks potential threats before they can attack or infect the computer. Any malware or other firmware code that is not recognized is blocked. For example, Secure Boot can prevent your computer from starting from illegally copied CDs or DVDs that could harm the computer. Secure Boot does not lock out valid recovery discs or Windows discs.
