1. Introduction

While dealing with the Suite B profile of CMC [RFC6403], a number of deficiencies were noted in the current base CMC specification. This document has a set of updates to [RFC5272], [RFC5273], and [RFC5274] to deal with those issues.

1.1. Requirements Terminology

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119].

1.2. Abbreviations

The following abbreviations are used in this document. Terms are used as defined in Section 2.1 of RFC 5272.

      CA   - Certification Authority
      CRL  - Certificate Revocation List
      CRMF - Certificate Request Message Format
      EE   - End-Entity
      MAC  - Message Authentication Code
      PKI  - Public Key Infrastructure
      RA   - Registration Authority

2. Updates to RFC 5272 - "Certificate Management over CMS (CMC)"

2.1. New Section 1.3 - "Updates Made by RFC 6402"

Insert this section before the current Section 1.3.

The following updates were made by RFC 6402.

Add new controls:

      RA Identity Witness  allows for an RA to perform identity checking
         using the identity and shared-secret, and then tell any
         following servers that the identity check was successfully
         performed.
      
      Response Body  allows for an RA to identify a nested response for
         an EE to process.

Create a new attribute, Change Subject Name, that allows a client to request a change in the subject name and subject alternate name fields in a certificate.

Add Extended Key Usages for CMC to distinguish server types.

Define a new Subject Information Access type to hold locations to contact the CMC server.

Clarify that the use of a pre-existing certificate is not limited to just renewal and rekey messages and is required for support. This formalizes a requirement for the ability to do renewal and rekey that previously was implicit.

2.2. Update Section 6 - "Controls"

Update Table 1 by adding the following rows:

   +--------------------------+-----------+-----------------+---------+
   | Identifier Description   | OID       | ASN.1 Structure | Section |
   +--------------------------+-----------+-----------------+---------+
   | id-cmc-raIdentityWitness | id-cmc 35 | BodyPartPath    | 6.20    |
   |                          |           |                 |         |
   | id-cmc-responseBody      | id-cmc 37 | BodyPartPath    | 6.21    |
   +--------------------------+-----------+-----------------+---------+

Addition to Table 1: CMC Control Attributes

2.3. Replace Section 6.3 - "Linking Identity and POP Information"

Replace the text of the section with the following text.

In a CMC Full PKI Request, identity proof information about the client is carried in the certificate associated with the signature of the SignedData containing the certification requests, one of the two identity proof controls or the MAC computed for the AuthenticatedData containing the certification requests. Proof-of-possession (POP) information for key pairs, however, is carried separately for each PKCS #10 or CRMF certification request. (For keys capable of generating a digital signature, the POP is provided by the signature on the PKCS #10 or CRMF request. For encryption-only keys, the controls described in Section 6.7 are used.) In order to prevent substitution-style attacks, the protocol must guarantee that the same entity supplied both the POP and proof-of-identity information.

We describe three mechanisms for linking identity and POP information: witness values cryptographically derived from a shared- secret (Section 6.3.1), shared-secret/subject name matching (Section 6.3.2), and subject name matching to an existing certificate (Section 6.3.3). Clients and servers MUST support the witness value and the certificate linking techniques. Clients and servers MAY support shared-secret/name matching or MAY support other bilateral techniques of similar strength. The idea behind the first two mechanisms is to force the client to sign some data into each certification request that can be directly associated with the shared-secret; this will defeat attempts to include certification requests from different entities in a single Full PKI Request.

2.4. Replace Section 6.3.3 - "Renewal and Rekey Messages"

Make the new section title "Existing Certificate Linking". Replace all text in this section with this text.

Linking between the POP and an identity is easy when an existing certificate is used. The client copies all of the naming information from the existing certificate (subject name and subject alternative name) into the new certification request. The POP on the new public key is then performed by using the new key to sign the identity information (linking the POP to a specific identity). The identity information is then tied to the POP information by signing the entire enrollment request with the private key of the existing certificate.

Existing certificate linking can be used in the following circumstances:

When replacing a certificate by doing a renewal or rekey certification request.

Using an existing certificate to get a new certificate. An example of this would be to get a key establishment certificate after having gotten a signature certificate.

Using a third-party certificate to get a new certificate from a CA. An example of this would be using a certificate and key pair distributed with a device to prove an identity. This requires that the CA have an out-of-band channel to map the identity in the device certificate to the new EE identity.

2.5. New Section 6.20 - "RA Identity Proof Witness Control"

Insert this section.

The RA Identity Proof Witness control allows an RA to indicate to subsequent control processors that all of the identity proof requirements have been met. This permits the identity proof to be performed at a location closer to the end-entity. For example, the identity proof could be done at multiple physical locations, while the CA could operate on a company-wide basis. The RA performs the identity proof, and potentially other tasks that require the secret to be used, while the CA is prevented from knowing the secret. If the identity proof fails, then the RA returns an error to the client denoting that fact.

The relevant ASN.1 for the RA Identity Proof Witness control is as follows:

      cmc-raIdentityWitness CMC-CONTROL ::=
         { BodyPartPath IDENTIFIED BY id-cmc-raIdentityWitness }
      
      id-cmc-raIdentityWitness OBJECT IDENTIFIER ::= {id-cmc 35}

The above ASN.1 defines the following items:

   cmc-raIdentityWitness  is a CMC-CONTROL associating the object
      identifier id-cmc-raIdentityWitness and the type BodyPartPath.
      This object is omitted from the 1988 module.  The object is added
      to the object set Cmc-Control-Set.  The control is permitted to
      appear only in the control sequence of a PKIData object.  It MUST
      NOT appear in the control sequence of a PKIResponse.  The control
      is permitted to be used only by an RA.  The control may appear
      multiple times in a control sequence with each occurrence pointing
      to a different object.
   
   id-cmc-raIdentityWitness  is the object identifier used to identify
      this CMC control.
   
   BodyPartPath  is the type structure associated with the control.  The
      syntax of BodyPartPath is defined in Section 3.2.2.  The path
      contains a sequence of body part identifiers leading to one of the
      following items:
   
      Identity Proof control  if the RA verified the identity proof in
         this control.
   
      Identity Proof Version 2 control  if the RA verified the identity
         proof in this control.
   
      Full PKI Request  if the RA performed an out-of-band identity
         proof for this request.  The request SHOULD NOT contain either
         Identity Proof control.
   
      Simple PKI Request  if the RA performed an out-of-band identity
         proof for this request.

The RA Identity Proof Witness control will frequently be associated with a Modify Certification Request control, which changes the name fields in the associated certification requests. This is because the

RA knows the actual name to be assigned to the entity requesting the certificate, and the end-entity does not yet have the details of the name. (The association would be set up by the operator at the time the shared-secret was generated by the RA.)

When this control is placed in a message, it is RECOMMENDED that the Control Processed control be placed in the body sequence as well. Using the explicit new control, rather than implicitly relying on the Control Processed control is important due to the need to know explicitly which identity proofs have been performed. The new control also allows an RA to state that out-of-band identity proofs have been performed.

When the identity proof is performed by an RA, the RA also MUST validate the linking between the identity proof and the name information wrapped inside of the key proof-of-possession.

2.6. New Section 6.21 - "Response Body Control"

Insert this section.

The Response Body Control is designed to enable an RA to inform an EE that there is an embedded response message that MUST be processed as part of the processing of this message. This control is designed to be used in a couple of different cases where an RA has done some additional processing for the certification request, e.g., as key generation. When an RA performs key generation on behalf of an EE, the RA MUST respond with both the original response message from the certificate issuer (containing the certificate issuance) as part of the response generated by the RA (containing the new key). Another case where this is useful is when the secret is shared between the RA and the EE (rather than between the CA and the EE) and the RA returns the Publish Trust Anchors control (to populate the correct trust points).

The relevant ASN.1 for the Response Body Control is as follows:

     cmc-responseBody CMC-CONTROL ::= {
        BodyPartPath IDENTIFIED BY id-cmc-responseBody
     }
     
     id-cmc-responseBody OBJECT IDENTIFIER ::= {id-cmc 37}

The above ASN.1 defines the following items:

   cmc-responseBody  is a CMC-CONTROL associating the object identifier
      id-cmc-responseBody with the type BodyPartPath.  This object is
      omitted from the 1988 module.  The object is added to the object
      set Cmc-Control-Set.  The control is permitted to appear only in
      the control sequence of a PKIResponse.  The control MUST NOT
      appear in the control sequence of a PKIData.  It is expected that
      only an intermediary RA will use this control; a CA generally does
      not need the control as it is creating the original innermost
      message.
   
   id-cmc-responseBody  is the object identifier used to identify this
      CMC control.
   
   BodyPartPath  is the type structure associated with the control.  The
      syntax of BodyPartPath is defined in Section 3.2.2.  The path
      contains a sequence of body part identifiers leading to a
      cmsSequence item which contains a PKIResponse within it.

2.7. New Section 7 - "Other Attributes"

Insert this section before the current Section 7.

There are a number of different locations where various types of attributes can be placed in either a CMC request or a CMC response message. These places include the attribute sequence of a PKCS #10 request, controls in CRMF (Section 6 of [RFC4211]), and the various CMS attribute sequences.

2.8. New Section 7.1 - "Change Subject Name Attribute"

Insert this section.

The Client Name Change Request attribute is designed for a client to ask for a change in its name as part of a certification request. Because of security issues, this cannot be done in the simple way of just changing the requested subject name in the certificate template. The name in the certification request MUST match the name in the certificate used to verify the request, in order that identity and possession proofs are correctly applied.

The relevant ASN.1 for the Client Name Change Request attribute is as follows:

      at-cmc-changeSubjectName ATTRIBUTE ::=
         { ChangeSubjectName IDENTIFIED BY id-cmc-changeSubjectName }
      
      id-cmc-changeSubjectName OBJECT IDENTIFIER ::= {id-cmc 36}
      
      ChangeSubjectName ::= SEQUENCE {
          subject             Name OPTIONAL,
          subjectAlt          SubjectAltName OPTIONAL
      }
      (WITH COMPONENTS {..., subject PRESENT} |
            COMPONENTS {..., subjectAlt PRESENT} )

The attribute is designed to be used as an ATTRIBUTE object. As such, the attribute is placed in one of the following two places:

The attributes field in a CertificationRequest.

The controls field of a CertRequest for a CRMF certification request.

The control is identified by the Object Identifier id-cmc-changeSubjectName.

The ASN.1 type associated with control is ChangeSubjectName. The fields of the structure are configured as follows:

   subject  contains the requested subject name for the new certificate.
   
   subjectAlt  contains the requested subject alternative name for the
      new certificate.

At least one of the fields in the sequence MUST be present when encoding the structure.

When the CA processes this attribute in a certification request, it will do the following:

If present, the subject field is copied to the name field of the template. If the subject field is absent, the name field of the template will be set to a empty sequence.

If present, the subjectAlt field is used as the content of a SubjectAltName extension in the certificate. If the subjectAlt field is absent, the subjectAltName extension is removed from the certificate template.

2.9. New Section 9 - "Certificate Requirements"

Insert this section before the current Section 8.

Certificates for servers used in the CMC protocol SHOULD conform to the profile defined in [RFC5280]. This document defines some additional items that MAY appear in CMC server certificates. Section 9.1 defines some additional values for the Extended Key Usage extension. Section 9.2 defines a new Subject Information Access value that allows for a CMC certificate to publish information on how to contact the services it provides.

2.10. New Section 9.1 - "Extended Key Usage"

Insert this section.

The Extended Key Usage (EKU) extension is used to restrict the use of a certificate to specific applications. We define three different EKUs in this document. The ASN.1 to define these EKUs is:

      id-kp-cmcCA OBJECT IDENTIFIER ::= { id-kp 27 }
      id-kp-cmcRA OBJECT IDENTIFIER ::= { id-kp 28 }
      id-kp-cmcArchive OBJECT IDENTIFIER ::= { id-kp 29 }

The usage description for each of the EKUs is as follows:

   CMC Certification Authorities  are identified by the id-kp-cmcCA
      extended key usage.  The certificate may be the same as or
      different than the CA certificate.  If a different certificate is
      used, the certificates containing the id-kp-cmcCA extended key
      usage SHOULD have the same name as the certificate used for
      issuing the certificates.  (Using a separate key pair for CMC
      protocol operations and for issuing certificates and CRLs
      decreases the number of operations for which the private key used
      to sign certificates and CRLs would be used.)
   
   CMC Registration Authorities  are identified by the id-kp-cmcRA
      extended key usage.  This usage is placed into RA certificates.
   
   CMC Archive Servers  are identified by the id-kp-cmcArchive extended
      key usage.  CMC Archive Servers and the associated protocol are to
      be defined in a future document.

2.11. New Section 9.2 - "Subject Information Access"

Insert this section.

The subject information access extension indicates how to access information and services for the subject of the certificate. We define a new value for use in this extension, to identify the different locations that CMC services will be available. If this value is placed in a certificate, an appropriate extended key usage defined in Section 9.1 MUST be included in the certificate as well.

The id-ad-cmc OID is used when the subject offers certification services using the CMC protocol. If the CMC services are available via HTTP or FTP, accessLocation MUST be a uniformResourceIdentifier. If the CMC services are available via electronic mail, accessLocation MUST be an rfc822Name. If CMC services are available using TCP/IP, the dNSName or iPAddress name forms MUST be used. Since the GeneralName data structure does not permit the inclusion of a port number, in the absence of other external configuration information, the value of 5318 should be used. (The port registration is in Section 3.2.) The semantics of other name forms of accessLocation (when accessMethod is id-ad-cmc) are not defined by this specification.

The ASN.1 type for this extension is GeneralName (see Section 4.2.1.8 of [RFC5280]).

   id-ad-cmc OBJECT IDENTIFIER ::= { id-ad 12 }

2.12. Update Section 8 - "Security Considerations"

Add the following paragraphs to the end of Section 8.

A number of controls such as the RA Identity Proof Witness control exist for an RA to either make assertions about or modify a certification request. Any upstream request processor, such as a CA, MUST verify that the RA is fully identified and authorized to make the assertion or modification it is claiming. If it is not identified or authorized, then any request MUST be rejected.

CMC servers, both RAs and CAs, need to perform due diligence in checking the contents of a certification request. At an absolute minimum, all fields should be checked to ensure that the policies of the CA/RA are correctly enforced. While all fields need to be checked, special care should be taken with names, name forms, algorithm choices, and algorithm parameters.

3. Updates to RFC 5273 - "Certificate Management over CMS (CMC):

Transport Protocols"

3.1. Update Section 5 - "TCP-Based Protocol"

Replace paragraph 3 in Section 5 with the following.

CMC requires a registered port number to send and receive CMC messages over TCP. The title of this IP Protocol number is "pkix-cmc". The value of this TCP port is 5318.

Prior to this update, CMC did not have a registered port number and used an externally configured port from the Private Port range. Client implementations MAY want to continue to allow for this to occur. Servers SHOULD change to use the new port. It is expected that HTTP will continue to be the primary transport method used by CMC installations.

3.2. New Section 6 - "IANA Considerations"

Insert this new section before the current Section 6.

IANA has assigned a TCP port number in the Registered Port Number range for the use of CMC.

   Service name: pkix-cmc
   Port Number: 5318
   Transport protocol: TCP
   Description: PKIX Certificate Management using CMS (CMC)
   Reference: RFC 6402
   Assignee: iesg@ietf.org
   Contact: chair@ietf.org

4. Updates to RFC 5274 - "Certificate Management Message over CMS

(CMC): Compliance Requirements"

4.1. Update to Section 4.2 - "Controls"

Add the following lines to the end of Table 1.

The following table lists the name and level of support required for each control.

             +---------------------------+-----+------+-----+
             | Control                   | EE  | RA   | CA  |
             +---------------------------+-----+------+-----+
             | RA Identity Proof Witness | N/A | MUST | (2) |
             |                           |     |      |     |
             | Response Body             | (6) | (6)  | N/A |
             +---------------------------+-----+------+-----+

Addition to Table 1: CMC Control Attributes

The following note should be added.

EE's SHOULD implement if designed to work with RAs and MUST implement if intended to be used in environments where RAs are used for identity validation or key generation. RAs SHOULD implement and validate responses for consistency.

5. IANA Considerations

This document contains a new IANA Considerations section to be added to [RFC5273] as part of this update.

6. Security Considerations

No changes are made to the existing security considerations of RFC 5273 and RFC 5274. The security considerations for RFC 5272 have been slightly modified (Section 2.12).
