Certificate Extension
Author(s) : S. Chokhani, S. Turner
Filename : draft-ietf-pkix-authorityclearanceconstraints-03.txt
Pages : 20

This document defines the syntax and semantics for the Clearance
attribute and the Authority Clearance Constraints extension in X.509
certificates. The Clearance attribute is used to indicate the
clearance held by the subject. The Clearance attribute may appear in
the subject directory attributes extension of a public key
certificate or in the attributes field of an attribute certificate.
The Authority Clearance Constraints certificate extension values in a
Trust Anchor (TA), Certificate Authority (CA) public key
certificates, and an Attribute Authority (AA) public key certificate
in a public key certification path constrain the effective Clearance
of the subject.
