Canonical, along with Red Hat, have today published a white paper on the potential implications, and benefits, of “Secure boot” – the new ‘locked in’ boot safeguard Microsoft will require all PCs to ship with should they want to install Windows 8.
Secure Boot is designed to protect users from malware – a noble aim. It achieves this by only allowing pre-approved and signed software contained to boot. Software that isn’t approved is*prohibited*from booting.
Microsoft, whose Windows 8 operating system will need Secure boot to be enabled by default, have laid out their idea of how secure boot should be*implemented*- one that will see users of alternate operating systems, such as Ubuntu, placed at a disadvantage.
Microsoft’s proposal places no requirement on system*manufacturers*to provide*users with an ‘off’ switch for Secure Boot, nor does it lay out a method for adding extra ‘trusted’ software and operating systems after a system has been bought.
Solution Canonical and Red Hat propose a different solution: one that provides users with the security afforded by Secure Boot, but one that also allows users to add more software and OSes – such as Linux – to the BIOS’ approval list.
This would, it’s hoped, allow users to run both Windows 8 and Linux, be it installed or on live media, on a PC with Secure Boot enabled.
Further still, the white paper suggests that PCs ship with a user-friendly interface for disabling/enabling secure boot altogether.

Intressant läsning om Windows 8, UEFI och secure boot.
Är det inte ett sakfel när det pratas om BIOS i artikeln?

2011-10-28, 18:42
Troligen inte. Det är BIOS som laddar bootsektorn. Och det är väl i samband med det som kontrollen skall göras att det är ett "godkänt" OS som håller på att laddas.

Jag hade fått för mej att BIOS är ute och ersatt med EFI på nya datorer.

Hm ...

Verkar vara lite överlapp i begreppen. Det blir nog tydligare med tiden. Exempelvis säljer tydligen PHEONIX ett BIOS som implementerar UEFI.
I ett annat fall gör man en BIOS som baseras på UEFI.

Phoenix Technologies currently sells Phoenix SecureCore Tiano and Phoenix MicroCore Bios implementing UEFI.
