Internet-Draft Clearance Sponsor Attribute March 2009
Abstract
This document defines the clearance sponsor 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 clearance sponsor attribute. This
attribute may be included in public key certificates [RFC5280],
attribute certificates [RFC3281bis], directories [X.500]/[RFC4512],
or locations that support attributes. These attributes 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. Clearance Sponsor
The clearance sponsor attribute indicates the sponsor of the
clearance of the object with which this attribute is associated.
This attribute is only meaningful if the clearance attribute
[RFC3281bis] is also present. The clearance sponsor attribute is a
DirectoryString [RFC5280], which MUST use the UTF8String CHOICE,
string with a minimum size of 1 characters and a maximum of 32
characters.
The following object identifier identifies the sponsor attribute:
id-aa-KP-clearanceSponsor OBJECT IDENTIFIER ::= {
joint-iso-ccitt(2) country(16) us(840) organization(1) gov(101)
dod(2) infosec(1) attributes(5) 68
}

Internet-Draft Clearance Sponsor Attribute March 2009
The ASN.1 syntax for the clearance sponsor attribute is as follows:
clearanceSponsor ATTRIBUTE ::= {
WITH SYNTAX DirectoryString { ub-clearance-sponsor }
EQUALITY-MATCHING RULE caseIgnoreMatch
SINGLE VALUE TRUE
IDENTIFIED BY id-clearanceSponsor
}
ub-clearance-sponsor INTEGER ::= 32
There must only be one value of clearanceSponsor associated with a
particular object.
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.
