Object Signing and Encryption (COSE)

Abstract:
This specification defines hybrid public-key encryption (HPKE) for
use with CBOR Object Signing and Encryption (COSE). HPKE offers a
variant of public-key encryption of arbitrary-sized plaintexts for a
recipient public key.
HPKE works for any combination of an asymmetric key encapsulation
mechanism (KEM), key derivation function (KDF), and authenticated
encryption with additional data (AEAD) function. Authentication for
HPKE in COSE is provided by COSE-native security mechanisms.
This document defines the use of the HPKE base mode with COSE. Other
modes are supported by HPKE but not by this specification.
