does look like secure boot. However, what it builds is a cryptographic verification system for the firmware payloads (and disables the shell for good measure). There is also an undocumented SECURE_BOOT build define instead; unfortunately this doesn’t even build (it craps out trying to add a...
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?
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...

I have an Asrock AMD system, I can enable and disable secure boot and I can reset the keys to some defaults, and I can see it is in setup mode. But, there seem no GUI in the UEFI to manually put my own PK and KEK…..
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-Secur...
UEFI modules to persist configuration data across boot cycles. Some of them (e.g., the variables related tosecure boot, such as db, dbx, PK, KEK, etc.) are dictated by the UEFI standard, while others don’t have any predefined meaning and their purpose is left to the O...
Rust stands out for its emphasis on safety, meaning developers often don't need as many external tools like static analyzers, which are commonly used with C. But Rust isn't rigid; if needed, it allows for exceptions with its "unsafe code" feature, giving developers some fl...
Bootkits, meaning rootkits running at the firmware level, have been utilized for this purpose. Once bootkits are installed, it can be extremely difficult to detect or remove versus OS-level rootkits as they are executed prior to the ac...
