The Higgins Selector Switch is a switching component that sits between a browser add-on on the one hand and one or more Identity Selectors on the other. The user decides what their "current" selector is. The browser requests a security token from the selector switch that then passes this request on to the current selector. It provides an app/UI to allow the user to change their default selector. It uses a "connector" architecture that allows developers to create new connectors for new Identity Selectors.
The Higgins Selector Switch is being developed for Higgins 1.1
Higgins Selector Switch is responsible for:
- Accepting I-Card token request from browser plug-in
- Dispatching token request to registered selector through selector connector
- Returning token from registered selector to browser
- Registering a default selector from available selectors
- Connectors for Higgins Selector Switch
- Higgins Information Card MIME handler for IE or Higgins Browser Extension for Firefox
The diagram below shows the relationship between two different browsers, the Higgins Selector Switch, the connectors and the Identity Selectors. As you can see different connectors use different techniques to invoke/launch their associated Selector. The connector that launches CardSpace, for example, uses a DLL, whereas the connector that launches the AIR Selector uses a TCP socket.
Note: at present there is no connector for the RCP Selector
Shown below are the utility sub-components that launch the selector switch on system startup as well as provide the UI to allow the user to change his/her choice of current selector
