discussions. Users want fast searching across the distributed
database on attributes different from the database structure.
Pre-computed indices satisfy this desire, though only for
specified searches.
Retrieval is obtaining additional information associated with a
person, such as an address, telephone number, email mailbox, or
security certificate.
Security certificates (a type of information associated with an
individual) are essential for the use of end-to-end
authentication, integrity, and privacy in Internet applications.
The development of secure applications in the Internet is
dependent on a directory system for retrieving the security
certificate associated with an individual. For example, the
privacy enhanced electronic mail (PEM) system has been developed
and is ready to go into service, and is now hindered by the lack
of an easily used directory of security certificates. An open
question is whether or not such a directory needs to be internally
secure.
2) What approaches will provide us with a white pages directory?
It is evident that there are and will be several technologies in
use. In order to provide a white pages directory service that
accommodates multiple technologies, we should promote
interoperation and work toward a specification of the simplest
common communication form that is powerful enough to provide the
necessary functionality. This "common ground" approach aims to
provide the ubiquitous WPS (White Pages Service) with a high
functionality and a low entry cost.
3) What are the problems to be overcome?
It must be much easier to be part of the Internet white pages than
to bring up a X.500 DSA (Directory Service Agent), yet we must
make good use of the already deployed X.500 DSAs. Simpler white
pages services (such as Whois++) must be defined to promote
multiple implementations. To promote reliable operation, there
must be some central management of the X.500 system. A common
naming scheme must be identified and documented. A set of index-
servers, and indexing techniques, must be developed. The storage
and retrieval of security certificates must be provided.
