Abstract
A method and system for communicating between a user network device and a server includes a first server and a user network device that requests an electronic token (eToken) from the first server. The first server communicates the eToken, a signature key, and a server time. The user network device determines a signature using the server time and signature key and communicates a request for data to a second server. The request for data includes a signature. The second server communicates data to a user network device.
