Secure Boot is a UEFI 2.3.1 specification that during the boot process verifies certificates (or keys) held in the firmware, and compares them to other Option ROMs and OS boot loaders. If the correct key is not in the firmware, or is in the “Blacklist”, Secure Boot will prevent the ...
Even if you only ever plan to run Windows or stock distributions of Linux that already have secure boot support, I’d encourage everybody who has a new UEFI secure boot platform to take ownership of it. The way you do this is by installing your own Platform Key. Once you have done thi...
KEK公钥需要由PK的私钥签名后安装到主板中，因为KEK的公钥安装到主板的时候主板会用PK的公钥进行验证。
Secure boot is only supported/enforced on Windows 8. This feature can be quite problematic as it won't allow you to boot any bootloaders that are not signed. Meaning once you enable it, you can't boot anything else unless you disable it or place it in "Custom" mode and configure publ...
We feel it is sufficiently safe. The MOK only allows signing kernel modules, and if someone has enough access (meaning, root access) to the system, they have already compromised it. I use special hardware that does not include Microsoft keys, how can I still use Secure Boot?

In addition, UEFI provides better security with the Secure Boot feature, preventing unauthorizedappsfrom booting. However, the downside is that Secure Boot prevents dual booting because it treats other OSes as unsigned apps. UEFI runs in 32-bit or 64-bit mode, allowing it to provide agraphical...
Please keep in mind if the Fabrikam Test KEK CA is the only KEK CA present (meaning there is no Windows KEK CA), the PC may boot into Windows RE. Prior to script execution, run "Set-ExecutionPolicy Bypass -Force" Import-Module secureboot try { Write-Host "Deleting db..." Set-Secu...
Security:UEFI offers more advanced security features, such as secure boot and firmware validation, providing better protection against malware and unauthorized access. User Interface:UEFI provides agraphical user interface(GUI), making it easier to navigate and configure settings, whereas BIOS typically ...
ESET researchers are the first to publish an analysis of BlackLotus, the first in-the-wild UEFI bootkit capable of bypassing UEFI Secure Boot.
