Solution to the distribution problem
It is difficult to get an overview of the huge number of trust centers and private Public Key Infrastructures. This leads to a high complexity referring to access and distribution of available certificates and certificate data (e.g. user certificates, revocation lists). It cannot be expected of a user to prepare numerous repository services in his applications for access. Ideally, in his applications, a user wants to configure only one central knot offering respective data.
This is why the EBCA makes available a centralized LDAP-directory that - when it is integrated - enables the users to request encryption certificates of persons they are corresponding with and to encrypt the data that wants to be sent to this person.
This service prevents users from being forced to handle a multitude of LDAP entries in their applications. Thus, not only administration expenses can be reduced considerably, but also the attractiveness to and acceptance of secure communication for the users is enhanced.
