Abstract
An internet service provider (ISP) is configured to provide notification messages such as service updates to subscribers via redirected web pages. In order for the web pages to be treated as originating from the ISP, the ISP provides a shared secret in the browser message. The shared secret may be a secret not derivable by viruses or trojans in the subscriber computer, such as a MAC address of the subscriber modem.
