Delegated Path Discovery
Encyclopedia
Delegated Path Discovery (DPD) is a method for querying a trusted server for information about a public key certificate
.
DPD allows clients
to obtain collated certificate information from a trusted DPD server
. This information may then be used by the client to validate the subject certificate.
The requirements for DPD are described in RFC 3379.

Server (computing)
In the context of client-server architecture, a server is a computer program running to serve the requests of other programs, the "clients". Thus, the "server" performs some computational task on behalf of "clients"...
. This information may then be used by the client to validate the subject certificate.
The requirements for DPD are described in RFC 3379.
