I would add that if you care about data integrity, then you will also want to include both a cryptographic hash, as well as some sort of sequencing information in the payload, so that consumers can detect attacks that may have, for example, removed or re-ordered messages.  If you're even more paranoid, you could also roll keys, so that compromise of a key at one point will not compromise the secrecy/integrity of previous messages, but that is obviously more complicated (== more expensive to implement).
