I was looking through APT packages for Quantal and I found one called linux-signed-image-generic, which only says that it's "Signed with the Ubuntu EFI key." The kernel package that it currently depends on says pretty much the same thing.
So if your hardware supports EFI (I think I'm running the signed kernel now) then what benefits does the signed kernel have? Is it just a security thing?

What ANSI C standard says about bit wise XOR of two signed integers ?
I have version 10.04 that I have been using. Normally there are about 5 entries on the bottom toolbar language, keyboard, session etc. There are 2 sign ins that I normally use. When I click on a user and enter the password, it simply returns to the sign on screen and there's only one entry on the toolbar for sessions.
Hi everybody...Months ago I used a custom ROM for my MK16 based on Jelly Bean. I wanted to replace Trebuchet with Nova so I did it but I had to sign the complete ROM using the tool from the picture, But now I'm working on a "transformation pack",consists mainly of system apps.
The .zip must be signed? I don't know where this tool came from, Can I use it?
I've just installed 12.04LTS on my relatively new desktop. The system is set to duel boot with Windows 8, uses UEFI, and secure boot is enabled. It seems to be working well now as long as I use a kernel version that is signed with Canonical's UEFI signing key. The repositories have both signed and unsigned versions of kernels available but Update Manager seems to pick the unsigned versions.
I am using Linode and have built a LAMP stack. I setup Google Apps (free edition) to handle all incoming mail. I've also setup Google Apps to use DKIM authentication. The problem is when my application sends mail (sign up verification, lost password, etc.) the email is not signed.
when a date type is considered signed and unsigned is that simple referring to - for signed and positive numbers for unsigned? Further if that is the case would mutiplying and dividing ect where 2 signed numbers, like (-2)*(-2) = 4 result in a unsigned.
A common misconception is that if a piece of code, such as an application, has been signed, it’s clean and safe to install. Wrong!
I assume you are asking about secure boot. This is not something that Arch Linux supports. To make it work you would need to use the shim loader as well as have your kernel and all modules signed. You can sign them yourself and then specify your key using the shim loader...
