                         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.

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
      }

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.
