Public Key Authenticated Encryption for JOSE: ECDH-1PU

Neil Madden

Abstract

This document describes the ECDH-1PU public key authenticated encryption algorithm for JWE. The algorithm is similar to the existing ECDH-ES encryption algorithm, but adds an additional ECDH key agreement between static keys of the sender and recipient. This additional step allows the recipient to be assured of sender authenticity without requiring a nested signed-then-encrypted message structure.
