I think "open" would mean the algorithms are known but not the key. The key would be something known to the user... it could be something like eReader users where the key is the credit card number. Or, it could be that a user creates a private/public key pair and provides their public key to the book stores. The problem here is that there is nothing tieing the user to that key pair, so they could just publish the private key with the ebook.
The advantage to using an "open" algorythm like AES or Blowfish or whatever is that no one owns it. Any reader software can implement that algorythm to read the book/file... all they would need would be for a way for the user to provide their key, either as a file or input in the UI.
