A method and a system is presented for managing attribute certificates. An
extension within an attribute certificate, called a distributed trust
path locator, allows an attribute certificate to be physically
disassociated from its supporting public key certificates while remaining
logically associated with its supporting public key certificates. The
user's attribute certificate and its supporting PKCs allows any server
using an attribute certificate to locate and retrieve the PKC of the user
and of the AC-issuing authority. The user is not required to communicate
his/her PKC to a target service. In addition, configuring the target
service to accept attribute certificates does not require the deployment
of a PKC for every AC-issuing authority.
