 <span class="h1">New ASN.1 Modules for the Public Key Infrastructure Using X.509 (PKIX)</span>

Abstract

   The Public Key Infrastructure using X.509 (PKIX) certificate format,
   and many associated formats, are expressed using ASN.1.  The current
   ASN.1 modules conform to the 1988 version of ASN.1.  This document
   updates those ASN.1 modules to conform to the 2002 version of ASN.1.
   There are no bits-on-the-wire changes to any of the formats; this is
   simply a change to the syntax.

<span class="grey"><a href="./rfc5912">RFC 5912</a>                   New ASN.1 for PKIX                  June 2010</span>


<span class="h2"><a class="selflink" id="section-1" href="#section-1">1</a>.  Introduction</span>

   Some developers would like the IETF to use the latest version of
   ASN.1 in its standards.  Most of the RFCs that relate to security
   protocols still use ASN.1 from the 1988 standard, which has been
   deprecated.  This is particularly true for the standards that relate
   to PKIX, Cryptographic Message Syntax (CMS), and S/MIME.

   This document updates the following RFCs to use ASN.1 modules that
   conform to the 2002 version of ASN.1 [<a href="#ref-ASN1-2002" title="&quot;ITU-T Recommendation X.680, X.681, X.682, and X.683&quot;">ASN1-2002</a>].  Note that not all
   the modules are updated; some are included to simply make the set
   complete.

   o  <a href="./rfc2560">RFC 2560</a>, PKIX Online Certificate Status Protocol (OCSP) [<a href="./rfc2560" title="&quot;X.509 Internet Public Key Infrastructure Online Certificate Status Protocol - OCSP&quot;">RFC2560</a>]

   o  <a href="./rfc2986">RFC 2986</a>, PKCS #10 certificate request [<a href="./rfc2986" title="&quot;PKCS #10: Certification Request Syntax Specification Version 1.7&quot;">RFC2986</a>]

   o  <a href="./rfc3279">RFC 3279</a>, PKIX algorithms and identifier [<a href="./rfc3279" title="&quot;Algorithms and Identifiers for the Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile&quot;">RFC3279</a>]

   o  <a href="./rfc3852">RFC 3852</a>, contains PKIX attribute certificates, version 1
      [<a href="./rfc3852" title="&quot;Cryptographic Message Syntax (CMS)&quot;">RFC3852</a>]

   o  <a href="./rfc4055">RFC 4055</a>, Additional Algorithms and Identifiers for RSA
      Cryptography [<a href="./rfc4055" title="&quot;Additional Algorithms and Identifiers for RSA Cryptography for use in the Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile&quot;">RFC4055</a>]

   o  <a href="./rfc4210">RFC 4210</a>, PKIX CMP (Certificate Management Protocol) [<a href="./rfc4210" title="&quot;Internet X.509 Public Key Infrastructure Certificate Management Protocol (CMP)&quot;">RFC4210</a>]

   o  <a href="./rfc4211">RFC 4211</a>, PKIX CRMF (Certificate Request Message Format) [<a href="./rfc4211" title="&quot;Internet X.509 Public Key Infrastructure Certificate Request Message Format (CRMF)&quot;">RFC4211</a>]

   o  <a href="./rfc5055">RFC 5055</a>, PKIX SCVP (Server-based Certificate Validation Protocol)
      [<a href="./rfc5055" title="&quot;Server-Based Certificate Validation Protocol (SCVP)&quot;">RFC5055</a>]

   o  <a href="./rfc5272">RFC 5272</a>, Certificate Management over CMS (CMC) [<a href="./rfc5272" title="&quot;Certificate Management over CMS (CMC)&quot;">RFC5272</a>]

   o  <a href="./rfc5280">RFC 5280</a>, PKIX certificate and Certificate Revocation List (CRL)
      profile [<a href="./rfc5280" title="&quot;Internet X.509 Public Key Infrastructure Certificate and Certificate Revocation List (CRL) Profile&quot;">RFC5280</a>] (both the implicit and explicit modules)

   o  <a href="./rfc5755">RFC 5755</a>, PKIX attribute certificates, version 2 [<a href="./rfc5755" title="&quot;An Internet Attribute Certificate Profile for Authorization&quot;">RFC5755</a>]

   Note that some of the modules in this document get some of their
   definitions from places different than the modules in the original
   RFCs.  The idea is that these modules, when combined with the modules
   in [<a href="./rfc5911" title="&quot;New ASN.1 Modules for Cryptographic Message Syntax (CMS) and S/MIME&quot;">RFC5911</a>] can stand on their own and do not need to import
   definitions from anywhere else.  Also note that the ASN.1 modules in
   this document have references in their text comments that need to be
   looked up in original RFCs, and that some of those references may
   have already been superseded by later RFCs.

   The document also includes a module of common definitions called
   "PKIX-CommonTypes".  These definitions are used here and in
   [<a href="./rfc5911" title="&quot;New ASN.1 Modules for Cryptographic Message Syntax (CMS) and S/MIME&quot;">RFC5911</a>].

   The document also includes a module of common definitions called
   "AlgorithmInformation".  These definitions are used here and in
   [<a href="./rfc5911" title="&quot;New ASN.1 Modules for Cryptographic Message Syntax (CMS) and S/MIME&quot;">RFC5911</a>].

<span class="h3"><a class="selflink" id="section-1.1" href="#section-1.1">1.1</a>.  Design Notes</span>

   The modules in this document use the object model available in the
   2002 ASN.1 documents to a great extent.  Objects for each of the
   different algorithm types are defined.  Also, all of the places where
   the 1988 ASN.1 syntax had ANY holes to allow for variable syntax now
   use objects.

   Much like the way that the PKIX and S/MIME working groups use the
   prefix of id- for object identifiers, this document has also adopted
   a set of two-, three-, and four-letter prefixes to allow for quick
   identification of the type of an object based on its name.  This
   allows, for example, the same back half of the name to be used for
   the different objects.  Thus, "id-sha1" is the object identifier,
   while "mda-sha1" is the message digest object for "sha1".

   One or more object sets for the different types of algorithms are
   defined.  A single consistent name for each different algorithm type
   is used.  For example, an object set named PublicKeys contains the
   public keys defined in that module.  If no public keys are defined,
   then the object set is not created.  When importing these object sets
   into an ASN.1 module, one needs to be able to distinguish between the
   different object sets with the same name.  This is done by using both
   the module name (as specified in the IMPORT statement) and the object
   set name.  For example, in the module for <a href="./rfc5280">RFC 5280</a>:

   PublicKeys FROM PKIXAlgs-2008 { 1 3 6 1 5 5 7 0 995 }
   PublicKeys FROM PKIX1-PSS-OAEP-Algorithms { 1 3 6 1 5 5 7  33 }

   PublicKeyAlgorithms PUBLIC-KEY ::= { PKIXAlgs-2008.PublicKeys, ...,
       PKIX1-PSS-OAEP-Algorithms.PublicKeys }

-- AlgorithmIdentifier

-- The first parameter represents the type of the algorithm being

-- The second parameter represents an object set containing the

--    The initial list of required algorithms should occur to the

--      occur to the right of an extension marker.
--
-- The object class ALGORITHM can be used for generic unspecified

--  S/MIME Capabilities
--
--  We have moved the SMIME-CAPS from the module for <a href="./rfc3851">RFC 3851</a> to here
--  because it is used in <a href="./rfc4262">RFC 4262</a> (X.509 Certificate Extension for
--  S/MIME Capabilities)
--
--
--  This class is used to represent an S/MIME capability.  S/MIME
--  capabilities are used to represent what algorithm capabilities
--  an individual has.  The classic example was the content encryption
--  algorithm RC2 where the algorithm id and the RC2 key lengths
--  supported needed to be advertised, but the IV used is not fixed.
--  Thus, for RC2 we used
--
--  cap-RC2CBC SMIME-CAPS ::= {
--      TYPE INTEGER ( 40 | 128 ) IDENTIFIED BY rc2-cbc }
--
--  where 40 and 128 represent the RC2 key length in number of bits.
--
--  Another example where information needs to be shown is for
--  RSA-OAEP where only specific hash functions or mask generation
--  functions are supported, but the saltLength is specified by the
--  sender and not the recipient.  In this case, one can either
--  generate a number of capability items,
--  or a new S/MIME capability type could be generated where
--  multiple hash functions could be specified.
--
--
--  SMIME-CAP
--
--  This class is used to associate the type that describes the
--  capabilities with the object identifier.
