The white paper doesn't say anything about additional public keys messages are encrypted for. It states that: - The private keys remain on the devices (which is good, but they don't need them to read your messages) - The messages can't be read by WhatsApp (they don't say anything about their parent company Facebook or governments though). If you read all the whitepapers and alert messages, you can totally read them in a way that allows Facebook to see, store and analyze the clear-text of every message you're sending, without anybody lying anywhere.
