M any of the problems facing the Internet today stem from the lack of a widely deployed, easily understood, secure identity solution. Microsoft’s Windows CardSpace software and the “Identity Metasystem” protocols underlying it are aimed at filling this gap using technology all can adopt and solutions all can endorse, putting people in control of their identity interactions on the Internet. One problem people face is knowing whether they’re at a legitimate web site or a malicious site. This is an identity problem: a problem with reliably identifying authentic sites to their users. People also face numerous problems in identifying themselves to the sites they use. Username/password authentication is the prevailing paradigm, but its weaknesses are all too evident on today’s Internet. Password reuse, insecure passwords, forgotten passwords, and poor password management practices open a world of attacks by themselves. Combine that with the password theft attacks enabled by counterfeit web sites and man-in-the-middle attacks and today’s Internet is an attacker’s paradise. CardSpace is part of the solution to all of these problems. T he Windows CardSpace software enables people to maintain a set of personal digital identities that are shown to them as visual “Information Cards”. These cards are easier to use than passwords. Furthermore, they employ strong cryptography, making them significantly more secure than passwords and other information typed into web forms.

W indows Communication Foundation: As a new, consolidated solution to creating distributed systems, Microsoft introduced Windows Communication Foundation (WCF) with the .NET Framework version 3.0. WCF encompasses all preceding distributed application development technologies offered by Microsoft and is capable of continuing to intercommunicate with those technologies for backward compatibility. WCF simplifies distribute application development while being extensible in order to keep up with and incorporate the latest technologies and advances. The following figure shows the WCF architecture. W CF provides: A n advanced system for configuring endpoints in a distributed environment T he ability to configure communication protocols to be used between endpoints A reliable system for sending and receiving messages between endpoints M essages may be sent asynchronously, secured, and managed through transactions F unctionality for serializing and deserializing primitive, complex, and binary data

W indows Workflow Foundation (WF) is used to document workflows, both system-based and human-based as well as a combination of both. A workflow is a real world set of activities that can be documented in their order of precedence W F is a layer on top of the .NET Framework version 3.0 and is created and maintained by using .NET programming languages. V isual Studio 2008 provides a designer for WF and all future Microsoft products that implement a workflow of some type (this includes most products) will utilize and benefit from WF. Workflows are documented graphically by using the WF designer and WF then mostly automates the creation of the underlying objects, code, and services.
