draft-harkins-cfrg-dnhpke-02
Abstract
This document describes enhancements to the Hybrid Public Key
Encryption standard published by CFRG. These include use of "compact
representation" of relevant public keys, support for key-wrapping,
and two ways to address the use of HPKE on lossy networks: a
determinstic, nonce-less AEAD scheme, and use of a rolling sequence
number with existing AEAD schemes.

1. Introduction
[RFC9180], hereinafter simply HPKE, is a robust, provably-secure
construct. It defines APIs to ensure proper use to retain its
security guarantees. These APIs are therefore rigid and purposeful.
Unfortunately, there are applications for which this rigidity is an
impediment to use: networks with bandwidth constrained mediums,
networks which cannot guarantee in-order delivery of every packet
sent, and for key-wrapping applications.
This memo proposes three modifications to HPKE to make it more
suitable for different use cases.
1.1. Compact Representation
HPKE generates an ephemeral keypair and uses it to perform a Diffie-
Hellman with the static keypair of the proposed recipient of a secure
message. The ephemeral public key is required to accompany the
message, or at least the first of a stateful sequence of messages.
HPKE therefore defines a serialization and deserialization for public
keys used with defined KEMs.
HPKE defines KEMs that use three Weierstrass curves defined in
[NISTCurves]. The serialization and deserialization for public keys
in these KEMs use the uncompressed form of an elliptic curve from
[SECG]. Unfortunately, this results in the string that accompanies
the message to be over twice as long as it needs to be. This can be
an issue for applications that have constrained bandwidth or that use
the HPKE APIs in a stateless, "single shot" mode where the message
being sent is dwarfed by the size of the serialized public key.
[RFC6090] defines a notion of "compact output" and "compact
representation" for elliptic curves. Compact output means that the
output of the ECDH operation is the x-coordinate of the resulting
point, the y-coordinate is discarded. Compact representation is a
way of communicating an elliptic curve Diffie-Hellman public key
using the x-coordinate only. Compact representation will work if
compact output is employed-- the sign of the ECDH secret is
irrelevant so it doesn't matter what the sign of the peer's public
key is.
Harkins Expires 10 February 2023 [Page 3]
Internet-Draft DNHPKE August 2022
HPKE uses compact output, it passes the x-coordinate of the ECDH
secret key to HKDF to derive a key to pass to the AEAD cipher. Since
HPKE uses compact output, it can define serialization and
deserialization that uses compact representation and thereby address
use cases in which message size is important. Redefining the
serialization and deserialization, though, requires definition of new
KEMs that will use the new technique.
1.2. Addressing Lossy Networks
To prevent the possibility of misuse, management of AEAD counters are
entirely constrained to the HPKE context. The sender and receiver
have no ability to know what particular counter was used with a
particular invocation or to manage how counters are used.
This restriction is not an issue for an applications that use HPKE
which have a guarantee of in-order packet delivery, where sender and
receiver HPKE contexts are kept in sync. But not everyone has a
guarantee of in-order delivery of packets and this restriction makes
use of HPKE impracticle by a great many use cases. Any undetected
packet loss or reordering would result in the sender and receiver
HPKE contexts getting out of sync. Since HPKE provides no way to
resynchronize such a situation, the result would be tragic.
Therefore, two techiques are added to allow HPKE to be used in lossy
networks or networks that reorder packets: a rolling window of
received sequence numbers, and a determinstic mode of AEAD.
1.2.1. Rolling Sequence Window
The technique from [RFC2401] can be adopted which implements a
rolling window that represents received messages (inside the window).
As the sequence number advances, and a message is successfully opened
thus validating the sequence number, the window advances to include
it. The result is that reorder and loss is acceptable for a number
of messages defined by the size of the window and messages deemed
"too old" are dropped. Messages replayed with a used sequence number
are also dropped.
To implement such a scheme, the receiver needs to know the counter
used with the AEAD algorithm. Therefore, the sequence number used to
construct the counter in HPKE (it is XOR'd with a secret base nonce)
is pre-peneded to the ciphertext.
Harkins Expires 10 February 2023 [Page 4]
Internet-Draft DNHPKE August 2022
1.2.2. Deterministic Authenticated Encryption
[SIV] defines a provably secure mode of deterministic authenticated
encryption (DAE). In this mode, a counter is optional. If one is
used and it is guaranteed to be unique, SIV achieves the same level
of IND-CCA2 security offered by other HPKE ciphers. But if the nonce
is reused or, in the case proposed here, the nonce is not used, SIV
will provide a different security guarantee, that of deterministic
security.
Determinsitic authenticity in a DAE scheme provides the traditional
inability of an adversary to come up with a non-trivial query that
will return a non-FAIL response-- i.e. a valid forgery-- with non-
negligible probability. Deterministic privacy in a DAE scheme
provides for the typical indistinguishability from random guarantee
of a traditional AEAD scheme, with a caveat: it cannot achieve the
indistinguishability goal that requires concealment of whether or not
a given plaintext was encrypted twice in a sequence of ciphertexts.
What this means is that the security of a DAE scheme is the same as a
traditional AE scheme with the exception that encrypting the same AAD
and the same plaintext twice will result in the same ciphertext, an
outcome an adversary would notice. Unlike other AEAD schemes, after
this misuse the privacy and authenticity guarantees remain, albeit
with this consideration to traffic analysis. This is a reasonable
price to pay for the ability to use the HPKE APIs as more than a
"single shot".
DAE can achieve the equivalent of semantic security if the message
space is random enough. This is the justification for the security
of key wrap schemes (see Section 1.3) in which (a portion of) the
plaintext is a random key.
SIV takes a vector of AAD. When a unique sequence number can be
managed it can be part of that vector. It should be noted,
therefore, that it is trivial for an application that has control of
the AAD to add a nonce as a component of the AAD vector to ensure
unique AAD per invocation of the HPKE API and achieve the IND-CCA2
notion of security.
Alternately, for some situations-- e.g. when the message protected by
HPKE is idempotent-- DAE security can be acceptable.
See Section 6.

Internet-Draft DNHPKE August 2022
1.3. Key Wrapping
Key wrapping schemes utilize a symmetric encryption algorithm to
provide privacy and integrity to cryptographic keying material.
Additionally, such schemes should provide integrity protection of
cleartext associated data which contains control information about
the wrapped key. Due to the symmetric nature of the algorithm, it is
assumed both sides possess a shared secret whose establishment is
problematic. Therefore HPKE is naturally an attractive option to use
to wrap a cryptographic key to a receipent's public key.
Since the data being wrapped is, in effect, random, a probabalistic
input like a nonce is not needed, hence the deterministic nature of
proposed key-wrapping schemes (see [X9102] and [RFC5649]). [SIV] is
superior to those schemes in a number of ways:
* it accepts associated data;
* it is more efficient;
* it accepts natural data lengths without requiring padding; and,
* it has a security proof.
Thus, making it well-suited for key wrapping use cases with HPKE.
2. Requirements Notation
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. Notation
This document re-uses the notation from HPKE and adds the following:
* "or(a,b)": logical OR of byte strings; "or(0x9876, 0x1234) =
0x9cf6". It is an error to call this function with two arguments
of unequal length.
* "and(a,b)": logical AND of byte strings; "and(0x1234, 0x5678) =
0x1230". It is an error to call this function with two arguments
of unequal length.
* "a | b": concatenation of byte strings "a" and "b". The length of
the resulting string is the sum of the lengths of "a" and "b". If

Internet-Draft DNHPKE August 2022
this symbol is on the left side of an equation it represents
distinct data, represented by "a" and "b", as the result of the
equation.
4. Modifying HPKE
4.1. Adding Compact Representation
New DHKEMs are defined for the three NIST curves, P-256, P-384, and
P-521. Being "compact", they are denoted here CP-256, CP-384, and
CP-521 but are, for the purposes of cryptography, otherwise
identical.
All KEM modes defined in HPKE are supported for these KEMs, including
Auth and AuthPSK.
+-------+---------------+---------+----+---+---+----+---------------+
| Value | KEM | Nsecret |Nenc|Npk|Nsk|Auth| Reference |
+=======+===============+=========+====+===+===+====+===============+
| TBD1 | DHKEM(CP-256, | 32 | 32 |32 |32 |yes | [NISTCurves], |
| | HKDF-SHA256) | | | | | | [RFC6090] |
+-------+---------------+---------+----+---+---+----+---------------+
| TBD2 | DHKEM(CP-384, | 48 | 48 |48 |48 |yes | [NISTCurves], |
| | HKDF-SHA384) | | | | | | [RFC6090] |
+-------+---------------+---------+----+---+---+----+---------------+
| TBD3 | DHKEM(CP-521, | 64 | 66 |66 |66 |yes | [NISTCurves], |
| | HKDF-SHA512) | | | | | | [RFC6090] |
+-------+---------------+---------+----+---+---+----+---------------+
Table 1: KEM IDs
These KEMs use the KDFs defined in HPKE and therefore are bound by
the input length restrictions of the KDF used (see 7.2.1 of HPKE).
The security properties of these KEMs satisfy the security
requirements of a KEM used in HPKE (see section 9.2 of HPKE).
4.1.1. SerializePublicKey and DeserializePublicKey
For CP-256, CP-384 and CP-521, the "SerializePublicKey()" function of
the KEM performs the Integer-to-Octet-String conversion of the
x-coordinate of the public key only, according to [RFC6090].
"DeserializePublicKey()" performs the Octet-String-to-Integer
conversion of [RFC6090] to produce the x-coordinate of a the
resulting point. Since all of these curves have a prime p = 3 mod 4,
the y-coordindate can be computed using the equation of the curve and
Shanks' method of computing the square root modulo p:
Harkins Expires 10 February 2023 [Page 7]
Internet-Draft DNHPKE August 2022
y = ((x^3 + a*x + b)^((p + 1)/4)) mod p
for a, b, and p defined for the curve in [NISTCurves]. There will be
two distinct solutions for y that will differ only in sign but either
one is acceptable to produce a Diffie-Hellman shared secret that is
used in compact output.
These deserialized public keys MUST be validated before they can be
used. See HPKE for specifics.
4.1.2. SerializePrivateKey and DeserializePrivateKey
As with HPKE, CP-256, CP-384, and CP-521 private keys are field
elements in the scalar field of the curve being used. Serialization
of the private key uses the Integer-to-OctetString function from
[RFC6090] and deserialization uses the OctetString-to-Integer
function from [RFC6090]. If the private key is an integer outside
the range "[0, order-1]", where "order" for each curve is defined in
[NISTCurves], the private key MUST be reduced, modulo the order, to
"[0, order-1]" before being serialized.
To catch invalid keys early on, implementers of DHKEMs SHOULD check
that deserialized private keys are not equivalent to 0 (mod "order"),
where "order" is the order of the curve.
4.2. Adding A Rolling Window
A rolling receiver replay window is added by overloading the way a
context encrypts and decrypts messages-- ContextS.Seal() and
ContextR.Open(). The calling parameters remain the same but the
internals change and, for ContextS.Seal(), the output differs.
The replay window is implemented as a bitmask check for a window
whose size is implementation-specific. For illustration purposes
only it is described here as being of size 32, meaning it can
tolerate loss and reorder of the previous 31 messages. The following
pseudo-code has separate routines for a quick check of a received
sequence number and an update to the window for sequence numbers that
have been validated.
The context encryption API template is the same as that in HPKE
except it prepends the sequence number, used to construct the counter
for the AEAD operation, to the data returned from Seal(). Therefore
the single "ct" output is, in fact, a concatenation of the four octet
sequence number and the returned ciphertext.
The context decryption API template is changed to extract the
sequence number from the input ciphertext, and check whether the
Harkins Expires 10 February 2023 [Page 8]
Internet-Draft DNHPKE August 2022
received sequence number is conditionally good. If it is and the
message is successfully opened, the window is updated with the
received sequence number.
Details are as follows:
windowSize = 32
def CheckSeq(num):
if num > self.seq
return Good
diff = self.seq - num
if diff > windowSize
return Bad
if and(self.window, (1 << diff)) == 0
return Good
else
return Bad
def UpdateWindow(num)
if num > self.seq
diff = num - self.seq
if diff < windowSize
self.window <<= diff
self.window = or(self.window, 1)
else
self.window = 1
self.seq = num
else
diff = self.seq - num
self.window = or(self.window, (1 << diff))
return
def ContextS.DSeal(aad, pt):
num = self.ComputeNonce(self.seq)
ct = num | Seal(self.key, num, aad, pt)
return ct
def ContextR.DOpen(aad, m):
num | ct = m
if CheckSeq(num) == Bad
raise OpenReplay
pt = Open(self.key, num, aad, ct)
if pt == OpenError
raise OpenError
else
UpdateWindow(num)
return pt
Harkins Expires 10 February 2023 [Page 9]
Internet-Draft DNHPKE August 2022
The window is added to the Encryption Context as well as a single
datum to indicate whether the rolling receiver replay window is used
(1) or not (0). When the replay window is used,
"Context<ROLE>.DOpen()" and "Context<ROLE>.DSeal()" are used, when it
is not the encryption and decryption operations from HPKE are used.
4.3. Adding DAE
AES-SIV, defined in [RFC5297] uses a "double-wide" key. A single
large key is passed to AES-SIV which divides the key into two, one
for encipherment and the other for authenticity. Since these cipher
modes are being added in their determinsitic, nonce-less varient the
nonce derived for these ciphers is zero (0).
Unlike other AEAD schemes, AES-SIV takes a vector of AAD. The number
of components of that vector is up to the application using AES-SIV
in HPKE.
+-------+-------------+----+----+-----------+
| Value | AEAD | Nk | Nn | Reference |
+=======+=============+====+====+===========+
| TBD4 | AES-256-SIV | 32 | 0 | [RFC5297] |
+-------+-------------+----+----+-----------+
| TBD5 | AES-512-SIV | 64 | 0 | [RFC5297] |
+-------+-------------+----+----+-----------+
Table 2: AEAD IDs
5. IANA Considerations
IANA is instructed to please update the "Hybrid Public Key
Encryption" repositories:
- assign values for TBD1, TBD2, and TBD3 from the HPKE KEM
Identifiers repository; and,
- assign values for TBD4, and TBD5 from the HPKE AEAD Identifiers
repository.
Please replace the TBD placeholders above with the assigned values.
6. Security Considerations
Since HPKE uses Diffie-Hellman in "compact output", the sign of the
public keys is irrelevant. Discarding that which has no impact on
the result, i.e. doing "compact representation", does not present a
security issue.
See [SIV] for a formal security proof.
Harkins Expires 10 February 2023 [Page 10]
Internet-Draft DNHPKE August 2022
Uses of the DAE ciphers in HPKE can achieve the same level of
security as the non-DAE ciphers if the calling application guarantees
unique AAD per invocation or if the calling application can guarantee
a random message space.
This opens up the possibility of misuse where an application
inadvertently makes a non-unique invocation, which is a good reason
to hide nonce management inside the HPKE context, as the existing
AEAD ciphers do. For some use cases-- e.g. messages are idempotent,
or a probabalistic operation can be achieved (e.g. key wrapping), the
DAE ciphers provide an acceptable option.
It deserves to be mentioned again that even if a nonce is reused
(i.e. misused) by an application wishing to manage the AAD of AES-
SIV, the security of the cipher is not completely voided as it is
with a non-DAE mode. The notion of deterministic privacy and
determinstic authenticity are retained (see [SIV]).
7. Acknowledgements
The algorithm for the sliding window to address dropped and reordered
messages was proposed by James Hughes and Harry Varnis in [RFC2401].

The following test vectors have been generated assuming the following
registry value assignments would be made by IANA:
* DHKEM(CP-256, HKDF-SHA256): 19
* DHKEM(CP-384, HKDF-SHA384): 20
* DHKEM(CP-521, HKDR-SHA512): 21
