New ASN.1 Modules for the Public Key Infrastructure Using X.509 (PKIX)

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.

RFC 5912 New ASN.1 for PKIX June 2010

1. Introduction

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 [ASN1-2002]. Note that not all
the modules are updated; some are included to simply make the set
complete.

o RFC 2560, PKIX Online Certificate Status Protocol (OCSP) [RFC2560]

o RFC 2986, PKCS #10 certificate request [RFC2986]

o RFC 3279, PKIX algorithms and identifier [RFC3279]

o RFC 3852, contains PKIX attribute certificates, version 1
[RFC3852]

o RFC 4055, Additional Algorithms and Identifiers for RSA
Cryptography [RFC4055]

o RFC 4210, PKIX CMP (Certificate Management Protocol) [RFC4210]

o RFC 4211, PKIX CRMF (Certificate Request Message Format) [RFC4211]

o RFC 5055, PKIX SCVP (Server-based Certificate Validation Protocol)
[RFC5055]

o RFC 5272, Certificate Management over CMS (CMC) [RFC5272]

o RFC 5280, PKIX certificate and Certificate Revocation List (CRL)
profile [RFC5280] (both the implicit and explicit modules)

o RFC 5755, PKIX attribute certificates, version 2 [RFC5755]

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 [RFC5911] 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have already been superseded by later RFCs.

Hoffman & Schaad Informational [Page 3]

RFC 5912 New ASN.1 for PKIX June 2010

The document also includes a module of common definitions called
"PKIX-CommonTypes". These definitions are used here and in
[RFC5911].

The document also includes a module of common definitions called
"AlgorithmInformation". These definitions are used here and in
[RFC5911].

1.1. Design Notes

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 RFC 5280:

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 }

-- S/MIME Capabilities
--
-- We have moved the SMIME-CAPS from the module for RFC 3851 to here
-- because it is used in RFC 4262 (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

-- Note - upper bounds on string types, such as TeletexString, are
-- measured in characters. Excepting PrintableString or IA5String, a
-- significantly greater number of octets will be required to hold
-- such a value. As a minimum, 16 octets or twice the specified
-- upper bound, whichever is the larger, should be allowed for
-- TeletexString. For UTF8String or UniversalString, at least four
-- times the upper bound should be allowed.

15. Security Considerations

Even though all the RFCs in this document are security-related, the
document itself does not have any security considerations. The ASN.1
modules keep the same bits-on-the-wire as the modules that they
replace.
