Device Owner Attribute
Abstract
This document defines the Device Owner attribute. It indicates the
entity (e.g., company, organization, department, agency) that owns
the device. This attribute may be included in public key
certificates and attribute certificates.
Status of This Memo
This document is not an Internet Standards Track specification; it is
published for informational purposes.

RFC 5916 Device Owner Attribute June 2010
1. Introduction
This document specifies the Device Owner attribute. It indicates the
entity (e.g., company, organization, department, agency) that owns
the device. This attribute is intended to be used in public key
certificates [RFC5280] and attribute certificates [RFC5755].
This attribute may be used in automated authorization decisions. For
example, when two peers are deciding whether to communicate, each
could check that the device owner present in the other device's
certificate is on an "approved" list. This check is performed in
addition to certification path validation [RFC5280]. The mechanism
for managing the "approved" list is beyond the scope of this
document.
NOTE: This document does not provide an equivalent Lightweight
Directory Access Protocol (LDAP) schema specification as this
attribute is targeted at public key certificates [RFC5280] and
attribute certificates [RFC5755]. Definition of an equivalent LDAP
schema is left to a future specification.
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 attribute is defined using ASN.1 [X.680], [X.681], [X.682], and
[X.683].
2. Device Owner
The Device Owner attribute indicates the entity (e.g., company,
organization, department, agency) that owns the device with which
this attribute is associated. Device Owner is an object identifier.
The following object identifier identifies the Device Owner
attribute:
id-deviceOwner OBJECT IDENTIFIER ::= {
joint-iso-ccitt(2) country(16) us(840) organization(1) gov(101)
dod(2) infosec(1) attributes(5) 69
}
Turner Informational [Page 2]
^L
RFC 5916 Device Owner Attribute June 2010
The ASN.1 syntax for the Device Owner attribute is as follows:
at-deviceOwner ATTRIBUTE ::= {
TYPE OBJECT IDENTIFIER
EQUALITY MATCHING RULE objectIdentifierMatch
IDENTIFIED BY id-deviceOwner
}
There MUST only be one value of Device Owner associated with a
device. Distinct owners MUST be represented in separate
certificates.
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. Including this attribute in a
public key certificate or attribute certificate ensures the value for
the device owner is integrity protected.
