1.  Introduction

   The Cryptographic Message Syntax (CMS) [RFC5652] is used to digitally
   sign, digest, authenticate, or encrypt arbitrary message contents.
   This specification describes the use of the four one-way hash
   functions in the SHA3 family (SHA3-224, SHA3-256, SHA3-384, and
   SHA3-512) [SHA3] with the CMS.  In addition, this specification
   describes the use of these four one-way hash functions with the
   RSASSA PKCS#1 version 1.5 signature algorithm [RFC8017] and the
   Elliptic Curve Digital Signature Algorithm (ECDSA) [DSS] with the CMS
   signed-data content type.

   This document should not be confused with RFC 8702 [RFC8702], which
   defines conventions for using the the SHAKE family of SHA3-based
   extensible output functions with the CMS.

1.1.  ASN.1

   CMS values are generated using ASN.1 [X.680], using the Basic
   Encoding Rules (BER) and the Distinguished Encoding Rules (DER)
   [X.690].

1.2.  Terminology

   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.

2.  Message Digest Algorithms

   One-way hash functions are also referred to as message digest
   algorithms.
   This section specifies the conventions employed by CMS
   implementations that support SHA3-224, SHA3-256, SHA3-384, and
   SHA3-512 [SHA3].

   Digest algorithm identifiers are located in the SignedData
   digestAlgorithms field, the SignerInfo digestAlgorithm field, the
   DigestedData digestAlgorithm field, and the AuthenticatedData
   digestAlgorithm field.

   Digest values are located in the DigestedData digest field and the
   Message Digest authenticated attribute.  In addition, digest values
   are input to signature algorithms.

   SHA3-224, SHA3-256, SHA3-384, and SHA3-512 produce output values with
   224, 256, 384, and 512 bits, respectively.  The object identifiers
   for these four one-way hash functions are as follows:

      hashAlgs OBJECT IDENTIFIER ::= { joint-iso-itu-t(2) country(16)
          us(840) organization(1) gov(101) csor(3) nistAlgorithm(4) 2 }

      id-sha3-224 OBJECT IDENTIFIER ::= { hashAlgs 7 }

      id-sha3-256 OBJECT IDENTIFIER ::= { hashAlgs 8 }

      id-sha3-384 OBJECT IDENTIFIER ::= { hashAlgs 9 }

      id-sha3-512 OBJECT IDENTIFIER ::= { hashAlgs 10 }

   When using the id-sha3-224, id-sha3-s256, id-sha3-384, or id-sha3-512
   algorithm identifiers, the parameters field MUST be absent; not NULL
   but absent.

3.  Signature Algorithms

   This section specifies the conventions employed by CMS
   implementations that support the four SHA3 one-way hash functions
   with the RSASSA PKCS#1 version 1.5 signature algorithm [RFC8017] and
   the Elliptic Curve Digital Signature Algorithm (ECDSA) [DSS] with the
   CMS signed-data content type.

   Signature algorithm identifiers are located in the SignerInfo
   signatureAlgorithm field of SignedData.  Also, signature algorithm
   identifiers are located in the SignerInfo signatureAlgorithm field of
   countersignature attributes.

   Signature values are located in the SignerInfo signature field of
   SignedData.  Also, signature values are located in the SignerInfo
   signature field of countersignature attributes.

3.1.  RSASSA PKCS#1 v1.5 with SHA3

   The RSASSA PKCS#1 v1.5 is defined in [RFC8017]}}.  When RSASSA PKCS#1
   v1.5 is used in conjunction with one of the SHA3 one-way hash
   functions, the object identifiers are:

      OID ::= OBJECT IDENTIFIER

      sigAlgs OBJECT IDENTIFIER ::= { joint-iso-itu-t(2) country(16)
          us(840) organization(1) gov(101) csor(3) nistAlgorithm(4) 3 }

      id-rsassa-pkcs1-v1-5-with-sha3-224 OID ::= { sigAlgs 13 }

      id-rsassa-pkcs1-v1-5-with-sha3-256 OID ::= { sigAlgs 14 }

      id-rsassa-pkcs1-v1-5-with-sha3-384 OID ::= { sigAlgs 15 }

      id-rsassa-pkcs1-v1-5-with-sha3-512 OID ::= { sigAlgs 16 }

   The algorithm identifier for RSASSA PKCS#1 v1.5 subject public keys
   in certificates is specified in [RFC3279], and it is repeated here
   for convenience:

      rsaEncryption OBJECT IDENTIFIER ::= { iso(1) member-body(2)
          us(840) rsadsi(113549) pkcs(1) pkcs-1(1) 1 }

   When the rsaEncryption, id-rsassa-pkcs1-v1-5-with-sha3-224, id-
   rsassa-pkcs1-v1-5-with-sha3-256, id-rsassa-pkcs1-v1-5-with-sha3-384,
   and id-rsassa-pkcs1-v1-5-with-sha3-512 algorithm identifier is used,
   AlgorithmIdentifier parameters field MUST contain NULL.

Internet-Draft           Using SHA3 with the CMS            October 2023


   When the rsaEncryption algorithm identifier is used, the RSA public
   key, which is composed of a modulus and a public exponent, MUST be
   encoded using the RSAPublicKey type as specified in [RFC3279].  The
   output of this encoding is carried in the certificate subject public
   key.  The definition of RSAPublicKey is repeated here for
   convenience:

      RSAPublicKey ::= SEQUENCE {
         modulus INTEGER, -- n
         publicExponent INTEGER } -- e

   When signing, the RSASSA PKCS#1 v1.5 signature algorithm generates a
   single value, and that value is used directly as the signature value.

3.2.  ECDSA with SHA3

   The Elliptic Curve Digital Signature Algorithm (ECDSA) is defined in
   [DSS].  When ECDSA is used in conjunction with one of the SHA3 one-
   way hash functions, the object identifiers are:

      sigAlgs OBJECT IDENTIFIER ::= { joint-iso-itu-t(2) country(16)
          us(840) organization(1) gov(101) csor(3) nistAlgorithm(4) 3 }

      id-ecdsa-with-sha3-224 OBJECT IDENTIFIER ::= { sigAlgs 9 }

      id-ecdsa-with-sha3-256 OBJECT IDENTIFIER ::= { sigAlgs 10 }

      id-ecdsa-with-sha3-384 OBJECT IDENTIFIER ::= { sigAlgs 11 }

      id-ecdsa-with-sha3-512 OBJECT IDENTIFIER ::= { sigAlgs 12 }

   When using the id-ecdsa-with-sha3-224, id-ecdsa-with-sha3-256, id-
   ecdsa-with-sha3-384, and id-ecdsa-with-sha3-512 algorithm
   identifiers, the parameters field MUST be absent; not NULL but
   absent.

   The conventions for ECDSA public keys is as specified in [RFC5480].
   The ECParameters associated with the ECDSA public key in the signers
   certificate SHALL apply to the verification of the signature.

   When signing, the ECDSA algorithm generates two values.  These values
   are commonly referred to as r and s.  To easily transfer these two
   values as one signature, they MUST be ASN.1 encoded using the ECDSA-
   Sig-Value defined in [RFC3279] and repeated here for convenience:

      ECDSA-Sig-Value ::= SEQUENCE {
          r  INTEGER,
          s  INTEGER }

4.  Message Authentication Codes using HMAC aand SHA3

   This section specifies the conventions employed by CMS
   implementations that support the HMAC [RFC2104] with SHA3 message
   authentication code (MAC).

   MAC algorithm identifiers are located in the AuthenticatedData
   macAlgorithm field.

   MAC values are located in the AuthenticatedData mac field.

   When HMAC is used in conjunction with one of the SHA3 one-way hash
   functions, the object identifiers are:

      hashAlgs OBJECT IDENTIFIER ::= { joint-iso-itu-t(2) country(16)
          us(840) organization(1) gov(101) csor(3) nistAlgorithm(4) 2 }

      id-hmacWithSHA3-224 OBJECT IDENTIFIER ::= { hashAlgs 13 }

      id-hmacWithSHA3-256 OBJECT IDENTIFIER ::= { hashAlgs 14 }

      id-hmacWithSHA3-384 OBJECT IDENTIFIER ::= { hashAlgs 15 }

      id-hmacWithSHA3-512 OBJECT IDENTIFIER ::= { hashAlgs 16 }

   When the id-hmacWithSHA3-224, id-hmacWithSHA3-256, id-
   hmacWithSHA3-384, and id-hmacWithSHA3-512 algorithm identifier is
   used, the parameters field MUST be absent; not NULL but absent.

5.  Key Derivation Functions

5.1.  HKDF with SHA3

   This section assigns four algorithm identifiers that can be employed
   by CMS implementations that support the HMAC-based Extract-and-Expand
   Key Derivation Function (HKDF) [RFC5869] with the SHA3 family of hash
   functions.  The CMS KEMRecipientInfo structure
   [I-D.ietf-lamps-cms-kemri] is one place where algrithim identifiers
   for key-derivation functions are needed.

   When HKDF is used in conjunction with one of the SHA3 one-way hash
   functions, the object identifiers are:

Internet-Draft           Using SHA3 with the CMS            October 2023


      id-alg OBJECT IDENTIFIER ::= { iso(1) member-body(2)
          us(840) rsadsi(113549) pkcs(1) pkcs-9(9) smime(16) 3 }

      id-alg-hkdf-with-sha3-224 OBJECT IDENTIFIER ::= { id-alg TBD1 }

      id-alg-hkdf-with-sha3-256 OBJECT IDENTIFIER ::= { id-alg TBD2 }

      id-alg-hkdf-with-sha3-384 OBJECT IDENTIFIER ::= { id-alg TBD3 }

      id-alg-hkdf-with-sha3-512 OBJECT IDENTIFIER ::= { id-alg TBD4 }

   When the id-alg-hkdf-with-sha3-224, id-alg-hkdf-with-sha3-256, id-
   alg-hkdf-with-sha3-384, and id-alg-hkdf-with-sha3-512 algorithm
   identifier is used, the parameters field MUST be absent; not NULL but
   absent.

5.2.  KDF2 and KDF3 with SHA3

   This section specifies the conventions employed by CMS
   implementations that employ either the KDF2 or KDF3 functions defined
   in [ANS-X9.44].  The CMS KEMRecipientInfo structure
   [I-D.ietf-lamps-cms-kemri] is one place where algorithm identifiers
   for key-derivation functions are needed.

   When KDF2 and KDF3 are used, they are identified by the id-kdf-kdf2
   and id-kdf-kdf3 object identifiers, respectively.  The algorithm
   identifier parameters carries an algorithm identifier to indicate
   which hash function is being employed.  To support SHA3, an algorithm
   identifier from Section 2 is carried in the parameter.

      x9-44 OBJECT IDENTIFIER ::= { iso(1) identified-organization(3)
          tc68(133) country(16) x9(840) x9Standards(9) x9-44(44) }

      x9-44-components OBJECT IDENTIFIER ::= { x9-44 components(1) }

      id-kdf-kdf2 OBJECT IDENTIFIER ::= { x9-44-components kdf2(1) }

      id-kdf-kdf3 OBJECT IDENTIFIER ::= { x9-44-components kdf3(2) }

6.  Security Considerations

   Implementations must protect the signer's private key.  Compromise of
   the signer's private key permits masquerade.

   When more than two parties share the same message-authentication key,
   data origin authentication is not provided.  Any party that knows the
   message-authentication key can compute a valid MAC, therefore the
   content could originate from any one of the parties.

Internet-Draft           Using SHA3 with the CMS            October 2023


   Implementations must randomly generate message-authentication keys
   and one-time values, such as the k value when generating a ECDSA
   signature.  In addition, the generation of public/private key pairs
   relies on a random numbers.  The use of inadequate pseudo-random
   number generators (PRNGs) to generate cryptographic such values can
   result in little or no security.  An attacker may find it much easier
   to reproduce the PRNG environment that produced the keys, searching
   the resulting small set of possibilities, rather than brute force
   searching the whole key space.  The generation of quality random
   numbers is difficult.  RFC 4086 [RFC4086] offers important guidance
   in this area, and Appendix 3 of FIPS Pub 186-4 [DSS] provides some
   PRNG techniques.

   Implementers should be aware that cryptographic algorithms become
   weaker with time.  As new cryptanalysis techniques are developed and
   computing performance improves, the work factor to break a particular
   cryptographic algorithm will reduce.  Therefore, cryptographic
   algorithm implementations should be modular allowing new algorithms
   to be readily inserted.  That is, implementers should be prepared to
   regularly update the set of algorithms in their implementations.

7.  IANA Considerations

   IANA is asked to assign one object identifier for the ASN.1 module in
   Appendix "Appendix.  ASN.1 Module" in the "SMI Security for S/MIME
   Module Identifiers (1.2.840.113549.1.9.16.0)" registry [IANA-MOD]:

      id-mod-sha3-oids-2023 OBJECT IDENTIFIER ::= {
         iso(1) member-body(2) us(840) rsadsi(113549) pkcs(1)
         pkcs-9(9) smime(16) mod(0) TBD0 }

   IANA is asked to assign four object identifiers for the HKDF using
   SHA3 algorithm identifiers in the "SMI Security for S/MIME Algorithms
   (1.2.840.113549.1.9.16.3)" registry [IANA-ALG]:

      id-alg-hkdf-with-sha3-224 OBJECT IDENTIFIER ::= { id-alg TBD1 }

      id-alg-hkdf-with-sha3-256 OBJECT IDENTIFIER ::= { id-alg TBD2 }

      id-alg-hkdf-with-sha3-384 OBJECT IDENTIFIER ::= { id-alg TBD3 }

      id-alg-hkdf-with-sha3-512 OBJECT IDENTIFIER ::= { id-alg TBD4 }
