> Issue #11 http://trac.tools.ietf.org/wg/jose/trac/ticket/11 proposes restructuring the JWE representation to remove the JWE Integrity Value field and instead use the RFC 5116 (AEAD) binary serialization to represent the Ciphertext, Initialization Vector, and Integrity Value values.  If this proposal is adopted, JWEs would then have three fields – the header, the encrypted key, and the RFC 5116 combination of the Ciphertext, Initialization Vector, and Integrity Value values.
