At the implementation layer, we intend to use the shim loader originally developed by Fedora – it’s a smart solution which avoids several nasty legal issues, and simplifies the certification/signing step considerably. This shim loader’s job is to load grub2 and verify it; this version of grub2 in turn will load kernels signed by a SUSE key only. We are currently considering to provide this functionality with SLE11 SP3 on fresh installations with UEFI Secure Boot present.
