The best way to check this, is to check against the Debian Keyring.
Either you download the Debian Keyring from keyring.debian.org like:
	rsync -az --progress \
	keyring.debian.org::keyrings/keyrings/debian-keyring.gpg \
and check against this keyring, or you check the Key-IDs via
http://db.debian.org/, but you need the fingerprint of those key IDs
