They provide a method from which users can obtain public key information for other users. While, in theory, this may seem somewhat trivial, there are many details that must be taken into consideration, such as certificate revocation mechanisms. Since certificates will not be valid forever, there must be a way in which users can obtain accurate information. The research in this thesis provides such a mechanism. This research uses a verification and retrieval process to allow users to access the necessary information. This method also reduces the load placed upon a Certificate Authority by making the user perform more operations
