As someone has to fiddle on this multiboot stuff at all... Eric mentioned one could implement the SECURE_BOOT (as it should be in 5.1 CVS for some month now) for ELF multiboot as well. Requirements to the image would be to have 64 bytes available for usage data (the md5-hash of the whole image including this storage-region with all 64 bytes set to zero, then encrypted with the private key which public counterpart is compiled into etherboot...) For more information, please have look into the 5.1 contrib section, the "safeboot" directory. The code is (at least the non-rsaeuro code) fairly trivial. Just a pity I don't understand where to put 64 bytes inside multiboot images, but I didn't even dig deeply into the MultiBoot specs. If you give me a hint, I can implement it myself.
