This week in San Diego we showcased the InfoCard and WS-Trust support by .NET Smartcard which basically hosts the Security Token Service (STS) . This STS generates the RSTR (Request Security token response) with signed SAML Assertion message in response to a RST (Request security token) message [Basic WS-Trust protocol for exchanging security tokens].
Normally as we all know that InfoCard system is part of Avalon/Indigo SDK BETA release (require .NET 2.0) and supports only self issued identity cards but for this demo we created a InfoCard System on .NET 1.1 and used WSE 2.0 SP2 to communicate to the STS hosted in Smart card.
Actually last year at Burton Catayst we did a similar kind of demo which showed hosting WS-Trust STS on Smartcard and implemented active profile of WS-Federation. In this demo we showed how user's identity can be secured stored and managed by Smartcard and can be used by InfoCard System on PC.
Below are some snapshots of the sample application and InfoCard selector GUI on .NET 1.1
1. Smart client application. [ A Service locator ]
2. Authenticate to Smart card.
3. Lookup for Service
4. Select a service
5. InfoCard Selector GUI (created by us, not same as that in Indigo)
6. Select the InfoCard. This GUI locates the InfoCard [Please note here it is the metadata] and show only the non-geeky part :). Data (user attributes) are in Smartcard.
7. Clicking on Show Details retrieve the data stored (corresponding to supported claims in InfoCard selected) in the Smartcard.
8. Clicking on submit sends to STS (in Smartcard) an RST and gets RSTR. Client application extracts the SAML Assertion from RSTR, embeddeds in the Soap Request to http://www.dotnetcard.com/Demos/InfoCard/wstrust-rp1/BlueMonkey.aspx.
