In "US Department of Energy Signs On to J2EE" (JavaWorld, May 2002), Jian Zhong and Mike Lehr discussed, at the architectural level, how to create a secure single sign-on (SSO) service for multiple n-tier Web applications. After months of intensive research, design, and implementation, the SSO they developed for the Energy Information Administration of the US Department of Energy is now in production to support real-world e-government applications. Since that article first published, many readers asked architectural and technical questions. In this article, Jian Zhong further discusses strategic considerations in developing an e-authentication service in enterprise environments. By reading this article, readers will gain deeper understanding of e-authentication, e-signature, and an enterprise architecture (EA) approach for reusability and information sharing.
