Yes, as I understand it the kernel key is used for module signing.
The most obvious new use for module signing is Secure Boot, so that
the kernel will only load modules signed with its key.

Is there one key for each kernel version, or is it specific to the installation? In the latter case, how do modules get signed when the kernel updates? (Disclaimer: I'm not trying to start an argument over module signing, I just want to learn a little more about how it works.)
