Signed binary support in the kernel

Does FreeBSD support signed binaries - similar to what other (Linux, 
that I've seen) systems can do where the kernel will refuse to run the 
binary unless it's passes a digital signature test.  I'm curious about 
how this works, if (and how) it could be implemented to help lock down a 
given system.
