Table of Contents

1. Introduction

[I-D.ietf-cose-hpke] defines how to use Hybrid Public Key Encryption (HPKE) with COSE using traditional Key Encapsulation Mechanisms (KEM) based on Elliptic-curve Diffie-Hellman (ECDH).

This document extends the set of registered HPKE algorithms to include Post-Quantum (PQ) and Post-Quantum/Traditional (PQ/T) hybrid KEMs, as defined in [I-D.ietf-hpke-pq]. These algorithms provide protection against attacks by cryptographically relevant quantum computers.

The term "PQ/T hybrid" is used here consistent with [I-D.ietf-hpke-pq] to denote a combination of post-quantum and traditional algorithms, and should not be confused with HPKE's use of "hybrid" to describe the combination of asymmetric and symmetric encryption.

2. Conventions and Definitions

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

3. Algorithm Identifiers

This section defines the COSE algorithm identifiers for PQ and PQ/T HPKE-based encryption. Each algorithm is defined by a combination of an HPKE KEM, a Key Derivation Function (KDF), and an Authenticated Encryption with Associated Data (AEAD) algorithm.

All algorithms defined in this section follow the same operational model as those in [I-D.ietf-cose-hpke], supporting both integrated encryption as defined in Section 3.2 of [I-D.ietf-cose-hpke] and key encryption as defined in Section 3.3 of [I-D.ietf-cose-hpke].

Test vectors for all algorithms defined in this section are provided in Appendix A.

3.1. PQ/T Hybrid Integrated Encryption Algorithms

The following table lists the algorithm identifiers for PQ/T hybrid integrated encryption, where HPKE directly encrypts the plaintext using COSE_Encrypt0 without a separate Content Encryption Key:

Table 1: PQ/T Hybrid Integrated Encryption Algorithms
Name Value HPKE KEM HPKE KDF HPKE AEAD
HPKE-8 TBD (Assumed: 54) MLKEM768-P256 (0x0050) SHAKE256 (0x0011) AES-256-GCM (0x0002)
HPKE-9 TBD (Assumed: 56) MLKEM768-P256 (0x0050) SHAKE256 (0x0011) ChaCha20Poly1305 (0x0003)
HPKE-10 TBD (Assumed: 58) MLKEM768-X25519 (0x647a) SHAKE256 (0x0011) AES-256-GCM (0x0002)
HPKE-11 TBD (Assumed: 60) MLKEM768-X25519 (0x647a) SHAKE256 (0x0011) ChaCha20Poly1305 (0x0003)
HPKE-12 TBD (Assumed: 62) MLKEM1024-P384 (0x0051) SHAKE256 (0x0011) AES-256-GCM (0x0002)
HPKE-13 TBD (Assumed: 64) MLKEM1024-P384 (0x0051) SHAKE256 (0x0011) ChaCha20Poly1305 (0x0003)

These algorithms combine ML-KEM with a traditional elliptic curve algorithm in a PQ/T hybrid KEM construction, with the goal that compromise of either the post-quantum or the traditional component alone does not undermine the security of the resulting encryption.

3.2. Pure PQ Integrated Encryption Algorithms

The following table lists the algorithm identifiers for pure post-quantum integrated encryption:

Table 2: Pure PQ Integrated Encryption Algorithms
Name Value HPKE KEM HPKE KDF HPKE AEAD
HPKE-14 TBD (Assumed: 66) ML-KEM-768 (0x0041) SHAKE256 (0x0011) AES-256-GCM (0x0002)
HPKE-15 TBD (Assumed: 68) ML-KEM-768 (0x0041) SHAKE256 (0x0011) ChaCha20Poly1305 (0x0003)
HPKE-16 TBD (Assumed: 70) ML-KEM-1024 (0x0042) SHAKE256 (0x0011) AES-256-GCM (0x0002)
HPKE-17 TBD (Assumed: 72) ML-KEM-1024 (0x0042) SHAKE256 (0x0011) ChaCha20Poly1305 (0x0003)

These algorithms provide pure post-quantum security using ML-KEM without a traditional algorithm component.

3.3. PQ/T Hybrid Key Encryption Algorithms

The following table lists the algorithm identifiers for PQ/T hybrid key encryption, where HPKE encrypts the Content Encryption Key using COSE_Encrypt with COSE_Recipient:

Table 3: PQ/T Hybrid Key Encryption Algorithms
Name Value HPKE KEM HPKE KDF HPKE AEAD
HPKE-8-KE TBD (Assumed: 55) MLKEM768-P256 (0x0050) SHAKE256 (0x0011) AES-256-GCM (0x0002)
HPKE-9-KE TBD (Assumed: 57) MLKEM768-P256 (0x0050) SHAKE256 (0x0011) ChaCha20Poly1305 (0x0003)
HPKE-10-KE TBD (Assumed: 59) MLKEM768-X25519 (0x647a) SHAKE256 (0x0011) AES-256-GCM (0x0002)
HPKE-11-KE TBD (Assumed: 61) MLKEM768-X25519 (0x647a) SHAKE256 (0x0011) ChaCha20Poly1305 (0x0003)
HPKE-12-KE TBD (Assumed: 63) MLKEM1024-P384 (0x0051) SHAKE256 (0x0011) AES-256-GCM (0x0002)
HPKE-13-KE TBD (Assumed: 65) MLKEM1024-P384 (0x0051) SHAKE256 (0x0011) ChaCha20Poly1305 (0x0003)

These are the key encryption counterparts of the PQ/T hybrid integrated encryption algorithms defined in Table 1.

3.4. Pure PQ Key Encryption Algorithms

The following table lists the algorithm identifiers for pure post-quantum key encryption:

Table 4: Pure PQ Key Encryption Algorithms
Name Value HPKE KEM HPKE KDF HPKE AEAD
HPKE-14-KE TBD (Assumed: 67) ML-KEM-768 (0x0041) SHAKE256 (0x0011) AES-256-GCM (0x0002)
HPKE-15-KE TBD (Assumed: 69) ML-KEM-768 (0x0041) SHAKE256 (0x0011) ChaCha20Poly1305 (0x0003)
HPKE-16-KE TBD (Assumed: 71) ML-KEM-1024 (0x0042) SHAKE256 (0x0011) AES-256-GCM (0x0002)
HPKE-17-KE TBD (Assumed: 73) ML-KEM-1024 (0x0042) SHAKE256 (0x0011) ChaCha20Poly1305 (0x0003)

These are the key encryption counterparts of the pure PQ integrated encryption algorithms defined in Table 2.

4. COSE Key Representation

Keys for the algorithms defined in this document use the "AKP" (Algorithm Key Pair) key type defined in [I-D.ietf-cose-dilithium].

In COSE_Key representation, the AKP key type uses kty value 7. The "pub" parameter (label: -1) contains the raw HPKE SerializePublicKey() output for the corresponding KEM as a byte string. The "priv" parameter (label: -2) contains the raw HPKE SerializePrivateKey() output as a byte string.

The "alg" parameter (label: 3) is REQUIRED for all AKP keys and MUST be set to the COSE algorithm value corresponding to the intended algorithm.

Examples of COSE keys for each algorithm are provided in Appendix A.

5. Security Considerations

The security considerations of [I-D.ietf-cose-hpke] and [I-D.ietf-hpke-pq] apply to this document.

This document does not register algorithms using ML-KEM-512. As noted in Section 3 of [I-D.ietf-hpke-pq], given the relative novelty of ML-KEM, there is concern that new cryptanalysis might reduce the security level of ML-KEM-512. Use of ML-KEM-768 or ML-KEM-1024 acts as a hedge against such cryptanalysis at a modest performance penalty.
