Abstract: One embodiment of the present invention provides a system that facilitates single sign-on services in a wireless environment. The system operates by receiving a request at an application server from a wireless gateway to access a partner application on behalf of a user. The system then determines if the wireless gateway holds a token granting access to the partner application on behalf of the user. If the wireless gateway does not hold the token, the system redirects the request to a single sign-on server. The single sign-on server then requests user authentication credentials from the user through the wireless gateway. After receiving the user authentication credentials, the system determines if the user is authorized to access the partner application. If so, the single sign-on server issues a token to the wireless gateway. This token grants wireless gateway access to the partner application on behalf of the user.

Abstract: A latching data system includes a memory element that is configured to store a data value. A latch input is coupled to the memory element, so that changes in the latch input change the data value stored in the memory element without waiting for an assertion of a clock signal. The system also includes a driver circuit that is configured to drive the data value stored in the memory element onto a latch output. The system additionally includes a clocking circuit that is configured to cause the driver circuit to drive the data value stored in the memory element onto the latch output in response to an assertion of the clock signal.
