Architecture of smart card authentication

This topic presents a high-level architecture of the components that comprise the ClearQuest Web smart card authentication feature. The components are discussed in the topics that follow.

At the top of the figure, there is a box representing a smart card with an arrow to another box representing a smart card reader. The smart card reader communicates with the smart card middleware, which, in turn, communicates with the web browser. Communication between the web browser and the IBM HTTP Server (IHS) is established through a firewall. Communication between the web browser and the firewall is by HTTPS, and between the firewall and the IBM HTTP Server is by SSL. The IBM HTTP Server communicates with WebSphere Application Server by SSL as well. The WebSphere Application Server instance contains ClearQuest Web server and Change Management Server (CM Server). ClearQuest Web server and CM Server communicate with the trust store, where the signer certificates reside; with the LDAP registry; and with the ClearQuest database.
