Internet-Draft Device Owner Attribute March 2009
Abstract
This document defines the deviceOwner attribute. This attribute may
be carried in a public key certificate in the Subject Directory
Attributes extension, in an attribute certificate in the attribute
field, in a directory as an attribute, or in protocols that support
attributes.
1. Introduction
This document specifies the Device Owner attribute. This attribute
may be included in public key certificates [RFC5280], attribute
certificates [RFC3281bis], directories [X.500]/[RFC4512], or
locations that support attributes. This attribute may be used in
authorization decisions.
1.1. 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. ASN.1 Syntax Notation
The attributes are defined using ASN.1 [X.680].
2. Device Owner
The Device Owner attribute indicates the country or organization that
owns the Device with which this attribute is associated. Device
Owner is a choice of ISO 3166 [ISO3166-1] and [ISO3166-2] country
codes or an object identifier that represents a group of nations, an
organization, or any entity other than a nation. One of the choices
MUST be present.
The following object identifier identifies the Device Owner
attribute:
id-aa-KP-deviceOwner OBJECT IDENTIFIER ::= {
joint-iso-ccitt(2) country(16) us(840) organization(1) gov(101)
dod(2) infosec(1) attributes(5) 69
}

Internet-Draft Device Owner Attribute March 2009
The ASN.1 syntax for the Device Owner attribute is as follows:
deviceOwner ATTRIBUTE ::= {
WITH SYNTAX DeviceOwner
EQUALITY MATCHING RULE deviceOwnerMatch
SINGLE VALUE TRUE
IDENTIFIED BY id-deviceOwner
}
DeviceOwner ::= CHOICE {
alpha2Country [0] PrintableString ( SIZE (2) ),
-- ISO 3166-1 2 Letter Codes (aka digram).
alpha3Country [1] PrintableString ( SIZE (3) ),
-- ISO 3166-1 3 Letter Codes (aka trigram).
alpha4Country [2] PrintableString ( SIZE (4) ),
-- ISO 3166-2 4 Letter Codes (ISO 3166-1 digram and a hyphen
-- followed by one alpha or numeric code).
alpha5Country [3] PrintableString ( SIZE (5) ),
-- ISO 3166-2 5 Letter Codes (ISO 3166-1 digram and a hyphen
-- followed by two alpha or numeric codes).
alpha6Country [4] PrintableString ( SIZE (6) ),
-- ISO 3166-2 6 Letter Codes (ISO 3166-1 digram and a hyphen
-- followed by three alpha or numeric codes).
numericCountry INTEGER ( SIZE (0...999) ),
-- ISO 3166-1 3 Digit Codes.
group OBJECT IDENTIFIER
}
There must only be one value of Device Owner associated with a
device.
NOTE: When an environment uses the Device Owner attribute, it is
important that the same CHOICE be used.
The following object identifier identifies the Device Owner matching
rule:
id-matching-rule-deviceOwnerMatch OBJECT IDENTIFIER ::= {
{ joint-iso-ccitt(2) country(16) us(840) organization(1) gov(101)
dod(2) infosec(1) matching-rules(9) 6 }
Turner Expires September 4, 2009 [Page 3]
Internet-Draft Device Owner Attribute March 2009
When performing a match the following matching rule is used:
deviceOwnerMatch MATCHING-RULE ::= {
SYNTAX DeviceOwner
ID id-matching-rule-deviceOwnerMatch
}
This rule returns a TRUE if and only if the DeviceOwner value exactly
matches the presented value.
3. Security Considerations
If this attribute is used as part of an authorization process, the
procedures employed by the entity that assigns each value must ensure
that the correct value is applied. Further, once applied to the
object it must be bound to the object; this binding is normally
performed by digitally signing over the object and the attribute to
ensure data integrity.
4. IANA Considerations
None: All identifiers are already registered. Please remove this
section prior to publication as an RFC.
