As far as I understand it, if someone manages to get hold of a device key and posts it on the internet, the AACS guys will come and revocate this device key. But if you post a processing key on the internet, the AACS guys will not know from which device key this processing key was calculated, so they cannot revoke the device key.

In other words posting a processing key on the internet allows many people to decrypt their HD DVD discs without having to search for VUKs first. At the same time the device key is still secret and so cannot be revoked.

Did I get this right?
