Abstract

   Authenticated Encryption with Associated Data (AEAD) algorithms
   provide confidentiality and integrity of data.  The extensive use of
   AEAD algorithms in various high-level applications has caused the
   need for AEAD algorithms with additional properties and motivated
   research in the area.  This document gives definitions for the most
   common of those properties intending to improve consistency in the
   field.

1.  Introduction

   An Authenticated Encryption with Associated Data (AEAD) algorithm is
   an extension of authenticated encryption, which provides
   confidentiality for the plaintext to be encrypted and integrity for
   the plaintext and some Associated Data (sometimes called Header).
   AEAD algorithms are used in numerous applications and have become an
   important field in cryptographic research.

1.1.  Background

   AEAD algorithms are formally defined in [RFC5116].  The main benefit
   of AEAD algorithms is that they provide data confidentiality and
   integrity and have a simple unified interface.

   The importance of the AEAD algorithms is mainly explained by their
   exploitation simplicity: they have a unified interface, easy-to-
   understand security guarantees, and are much easier to implement
   properly than MAC and encryption schemes separately.  Therefore,
   their embedding into high-level schemes and protocols is highly
   transparent since, for example, there is no need for additional key
   derivation procedures.  Apart from that, when using the AEAD
   algorithm, it is possible to reduce the key and state sizes and
   improve the data processing speed.  For instance, such algorithms are
   mandatory for TLS 1.3 [RFC8446], IPsec ESP [RFC4303] [RFC8221], and
   QUIC [RFC9000].  Hence, the research and standardization efforts in
   the field are extremely active.  Most AEAD algorithms usually come
   with security guarantees, formal proofs, usage guidelines, and
   reference implementations.

   Even though providing core properties of AEAD algorithms is enough
   for many applications, some environments require other unusual
   cryptographic properties, which commonly require additional analysis
   and research.  With the growing number of such properties and
   research papers, misunderstanding and confusion inevitably appear.
   Some properties might be understood in different ways; for some, only
   non-trivial formal security notions are provided, while others
   require modification or extension of the standard AEAD interface to
   support additional functionality.  Therefore, the risk of misuse of
   AEAD algorithms increases, which can lead to security issues.

1.2.  Scope

   In the following document, we provide a short overview of the most
   common properties of AEAD algorithms by giving high-level definitions
   of these properties in Section 4.  The document aims to improve
   clarity and establish a common language in the field.

2.  Conventions Used in This Document

   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.  AEAD algorithms

   This section gives a general definition of an AEAD algorithm
   following [RFC5116].

   Definition.  An AEAD algorithm is defined by two operations, which
   are authenticated encryption and authenticated decryption:

   *  A deterministic operation of authenticated encryption has four
      inputs, each a binary string: a secret key K of a fixed bit
      length, a nonce N, associated data A, and a plaintext P.  The
      plaintext contains the data to be encrypted and authenticated, and
      the associated data contains the data to be authenticated only.
      Each nonce value must be unique in every distinct invocation of
      the operation for any particular value of the key.  The
      authenticated encryption operation outputs a ciphertext C.

   *  A deterministic operation of authenticated decryption has four
      inputs, each a binary string: a secret key K of a fixed bit
      length, a nonce N, associated data A, and a ciphertext C.  The
      operation verifies the integrity of the ciphertext and associated
      data and decrypts the ciphertext.  It returns a special symbol
      FAIL if the inputs are not authentic; otherwise, the operation
      returns a plaintext P.

   For more details on AEAD definition, please refer to [RFC5116].

   Throughout this document, by default, we will consider nonce-based
   AEAD algorithms, which have an interface from the definition above,
   and give no other restrictions on their structure.  However, some
   properties defined in the document apply only to particular classes
   of such algorithms, like block cipher-based AEAD algorithms (such
   algorithms use block cipher as a building block).  If that is the

Bozhko                  Expires 11 September 2023               [Page 4]
Internet-Draft        Properties of AEAD algorithms           March 2023

   case, we explicitly point that out in the corresponding section.
   Some other properties, on the contrary, are defined for algorithms
   with extended or completely different interfaces.  We address that
   issue in Section 4.1.

   We will call an AEAD algorithm secure if it provides such properties
   as Confidentiality and Data integrity, defined in Section 4.2,
   against any active nonce-respecting adversary.  Even though we aim to
   give high-level definitions, we sometimes use the advantage notion.
   Specifically, we will use the Authenticated Encryption advantage
   notion.  We adopt the corresponding definition from
   [I-D.irtf-cfrg-aead-limits].

   Definition.  Authenticated Encryption advantage is the probability of
   an active adversary succeeding in breaking the authenticated-
   encryption properties of the AEAD algorithm.  In this document, the
   definition of authenticated encryption advantage roughly is the
   probability that an attacker successfully distinguishes the
   ciphertext outputs of the AEAD scheme from the outputs of a random
   function or is able to forge a ciphertext that will be accepted as
   valid.

4.  AEAD properties

4.1.  Classification of AEAD properties

   In this document we use a high-level classification of additional
   properties.  The classification aims to give an intuition on how one
   can benefit from the property.  The additional properties fall into
   one of these three categories:

   *  Security properties.  We say that the property is a security
      property if it considers new threats or adversarial capabilities,
      in addition to those of the usual nonce-respecting adversary,
      which aims to break confidentiality or data integrity.

   *  Implementation properties.  We say that the property is an
      implementation property if it allows for more efficient
      implementations of the AEAD algorithm in special cases or
      environments.

   *  Additional functionality properties.  We say that the property is
      an additional functionality property if it provides new features
      in addition to the regular authenticated encryption with
      associated data.

Internet-Draft        Properties of AEAD algorithms           March 2023

   We notice that the distinction between the security and additional
   functionality properties might be vague.  The convention in this
   document is that additional functionality requires some extension of
   the standard AEAD interface.  In fact, each additional functionality
   property defines a new class of algorithms, which is not a subclass
   of regular AEAD.  Hence, the basic threats and adversarial
   capabilities must be redefined for each of these classes.  As a
   result, additional functionality properties consider the basic
   threats and adversarial capabilities for their class of algorithms
   and, in contrast to security properties, not the extended ones.

4.2.  Base properties

4.2.1.  Confidentiality

   Definition.  An AEAD algorithm guarantees that the plaintext is
   available only to those authorized to obtain it, i.e., those
   possessing the secret key.  That property is required for the AEAD
   algorithm to be called secure.

   Synonyms.  Privacy.

   Further reading.  [R2002], [BN2000]

4.2.2.  Data integrity

   Definition.  An AEAD algorithm guarantees that the plaintext and the
   associated data have not been changed or forged by those not
   authorized to, i.e., those not possessing the secret key.  That
   property is required for the AEAD algorithm to be called secure.

   Synonyms.  Message authentication.

   Further reading.  [R2002], [BN2000]

4.3.  Security properties

4.3.1.  Blockwise security

   Definition.  An AEAD algorithm provides security even if an adversary
   can adaptively choose the next block of the plaintext depending on
   already computed ciphertext blocks during an encryption operation.

   Note.  The case when an adversary can adaptively choose the next
   block of the ciphertext depending on already computed blocks of the
   plaintext, which appear in the device memory before the integrity
   verification during the decryption, can also be considered.  This
   case is strongly related to RUP security, defined in Section 4.3.9.

   Further reading.  [JMV2002], [FJMV2004]

4.3.2.  Key Dependent Messages (KDM) security

   Definition.  An AEAD algorithm provides security even when key-
   dependent plaintexts are encrypted.

   Notes.  KDM security is achievable only if nonces are chosen randomly
   and associated data is key-independent.

   Further reading.  [BK2011]

4.3.3.  Key commitment

   Definition.  An AEAD algorithm guarantees that it is difficult to
   find a tuple of the nonce, associated data, and ciphertext such that
   it can be decrypted correctly with more than one key.

   Synonyms.  Key-robustness, key collision resistance.

   Further reading.  [FOR17], [LGR21], [GLR17]

4.3.4.  Leakage resistance

   Definition.  An AEAD algorithm provides security even if some
   additional information about computations of an encryption (and
   possibly decryption) operation is obtained via side-channel leakages.

   Further reading.  [GPPS19], [B20]

4.3.5.  Multi-user security

   Definition.  An AEAD algorithm Authenticated Encryption advantage
   increases sublinearly in the number of users.

   Further reading.  [BT16]

4.3.6.  Nonce misuse

   Definition.  An AEAD algorithm provides security (resilience or
   resistance) even if an adversary can repeat nonces in its encryption
   queries.  Nonce misuse resilience and resistance are defined as
   follows:

   *  Nonce misuse resilience.  Security is provided only for messages
      encrypted with unique nonces.

   *  Nonce misuse resistance.  Security is provided for all messages.

   Further reading.  [RS06], [ADL17]

4.3.7.  Nonce-hiding

   Definition.  An AEAD algorithm decryption operation doesn't require
   the nonce to perform decryption and provides privacy for the nonce
   value used for encryption.

   Note.  In nonce-hiding AEAD algorithms, the ciphertext contains
   information equivalent to an encrypted nonce.  Hence, retrieving
   information about nonce from the ciphertext has to be difficult.

   Further reading.  [BNT19]

4.3.8.  Reforgeability resilience

   Definition.  An AEAD algorithm guarantees that once a successful
   forgery for the algorithm has been found, it is still hard to find
   any subsequent forgery.

   Further reading.  [BC09], [FLLW17]

4.3.9.  Release of unverified plaintext (RUP) security

   Definition.  An AEAD algorithm provides security even if the
   plaintext is released for every ciphertext, including those with
   failed integrity verification.

   Further reading.  [A14]

4.4.  Implementation properties

4.4.1.  Inverse-free

   Definition.  A block cipher-based AEAD algorithm can be securely
   implemented without evaluating the block cipher inverse.

4.4.2.  Lightweight

   Definition.  An AEAD algorithm can be efficiently and securely
   implemented on resource-constrained devices.  In particular, it meets
   the criteria required in the NIST Lightweight Cryptography
   competition [MBTM17].

4.4.3.  Online

   Definition.  An AEAD algorithm encryption (decryption) operation can
   be implemented with a constant memory and a single one-direction pass
   over the plaintext (ciphertext), writing out the result during that
   pass.

   Further reading.  [HRRV15] [FJMV2004]

4.4.4.  Parallelizable

   Definition.  An AEAD algorithm can fully exploit the parallel
   computation infrastructure.

   Synonyms.  Pipelineable.

   Further reading.  [C20]

4.4.5.  Single pass

   Definition.  An AEAD algorithm encryption (decryption) operation can
   be implemented with a single pass over the plaintext (ciphertext).

4.4.6.  Static Associated Data

   Definition.  An AEAD algorithm allows pre-computation for static (or
   repeating) associated data so that static AD doesn't significantly
   contribute to the computational cost of encryption.

4.4.7.  ZK-friendly

   Definition.  An AEAD algorithm operates on binary and prime fields
   with a low number of non-linear operations (often called
   multiplicative complexity).  Thus, it allows efficient implementation
   using a domain-specific language (DSL) for writing zk-SNARKs
   circuits.

   Synonyms.  ZK-focused, Arithmetization-oriented, Low Multiplicative
   Complexity

4.5.1.  Incremental

   Definition.  An AEAD algorithm allows encrypting and authenticating a
   message (associated data and a plaintext pair), which only partly
   differs from some previous message, faster than processing it from
   scratch.

   Further reading.  [SY16], [BKY02], [M05]

4.5.2.  Remotely-keyed

   Definition.  An AEAD algorithm can be implemented with most of the
   operations in encryption/decryption performed by an insecure (i.e.,
   it leaks all intermediate values) device, which has no access to the
   key, while another secure device performs operations involving the
   key.

   Further reading.  [BFN98], [DA03]

4.5.3.  Robust

   Definition.  An AEAD algorithm allows the user to choose an arbitrary
   value l >= 0 for every plaintext and then encrypts it into a
   ciphertext, which is l bits longer.

   Further reading.  [HKR2015]

5.  Security Considerations

   This document defines the properties of AEAD algorithms.  However,
   the document does not describe any concrete mechanisms providing
   these properties, neither it describes how to achieve them.  In fact,
   one can claim that an AEAD algorithm provides any of the defined
   properties only if its analysis in the relevant models was carried
   out.

6.  IANA Considerations

   This document has no IANA actions.
