Abstract Abstract
This document describes a scheme for hybrid public-key encryption This document describes a scheme for hybrid public key encryption
(HPKE). This scheme provides a variant of public-key encryption of (HPKE). This scheme provides a variant of public key encryption of
arbitrary-sized plaintexts for a recipient public key. It also arbitrary-sized plaintexts for a recipient public key. It also
includes three authenticated variants, including one which includes three authenticated variants, including one that
authenticates possession of a pre-shared key, and two optional ones authenticates possession of a pre-shared key and two optional ones
which authenticate possession of a KEM private key. HPKE works for that authenticate possession of a key encapsulation mechanism (KEM)
any combination of an asymmetric key encapsulation mechanism (KEM), private key. HPKE works for any combination of an asymmetric KEM,
key derivation function (KDF), and authenticated encryption with key derivation function (KDF), and authenticated encryption with
additional data (AEAD) encryption function. Some authenticated additional data (AEAD) encryption function. Some authenticated
variants may not be supported by all KEMs. We provide instantiations variants may not be supported by all KEMs. We provide instantiations

well as any authentication data, encoded in a manner described by the well as any authentication data, encoded in a manner described by the
individual AEAD scheme. Some implementations are not structured in individual AEAD scheme. Some implementations are not structured in
this way, instead providing a separate ciphertext and authentication this way, instead providing a separate ciphertext and authentication
tag. When such AEAD implementations are used in HPKE tag. When such AEAD implementations are used in HPKE
implementations, the HPKE implementation must combine these inputs implementations, the HPKE implementation must combine these inputs
into a single ciphertext value within "Seal()", and parse them out into a single ciphertext value within Seal() and parse them out
within "Open()", where the parsing details are defined by the AEAD within Open(), where the parsing details are defined by the AEAD
scheme. For example, with the AES-GCM schemes specified in this scheme. For example, with the AES-GCM schemes specified in this
document, the GCM authentication tag is placed in the last Nt bytes document, the GCM authentication tag is placed in the last Nt bytes
of the ciphertext output. of the ciphertext output.
11. IANA Considerations 11. IANA Considerations
This document requests the creation of three new IANA registries: IANA has created three new registries:
* HPKE KEM Identifiers * HPKE KEM Identifiers
* HPKE KDF Identifiers * HPKE KDF Identifiers
* HPKE AEAD Identifiers * HPKE AEAD Identifiers
All these registries should be under a heading of "Hybrid Public Key All these registries are under "Hybrid Public Key Encryption", and
Encryption", and administered under a Specification Required policy administered under a Specification Required policy [RFC8126].
