Is there a signing key available from a public keyserver? I've never
made packages, but I've added signing keys for "private" repositories
before - it's a 2-liner - something like:

"
gpg --keyserver pgpkeys.mit.edu --recv-key 2D230C5F
gpg -a --export 2D230C5F | sudo apt-key add -
"

here's a good reference: http://wiki.debian.org/SecureApt
