I can't believe that this firmware images are radically different, so there might/should be a way to compress them efficiently.

The firmware images might already be compressed, in which case you cannot make them any smaller.

If they're encrypted as well as signed, we can forget about compressing them too.

I hope they don't end up part of the standard kernel firmware tarball. That's bloated enough as it is.

All true, but nvidia itself should be interested in making smaller images.
So instead of providing N full signed blobs it could provide 1 Big blob and N-1 delta blobs, and load two files into video card, and hardware deal with delta, compression and encryption.
So it should be safe and small in size.

Why would nvidia care about size? Current setup works for them.
