Abstract
User and network computer client device (NC) registration with an internet service provider (ISP) occurs in two phases: the first phase with the relationship server and the second phase with the ISP. In the first phase, the NC sends the relationship server a unique identifier of the NC manufacturer, such as the manufacturer identification number. In the preferred embodiment, the NC also transmits an enterprise identification number from a smart card uniquely specifying the ISP to which the user wishes to connect. The relationship server queries a relationship database using the manufacturer and enterprise identification numbers. In the preferred embodiment, the relationship server determines whether the specified manufacturer has authorized connection to the specified ISP; if no authorization exists in the relationship server database, then the relationship server disconnects from the NC. Otherwise, the relationship server transmits NC connection information and initial registration contents for the ISP to the NC. The NC preferably writes the initial registration contents to the user's smart card. In the preferred embodiment, the initial registration contents is identical for all users of the same ISP and is digitally signed by the ISP. The second phase of the user registration is entirely governed by the ISP. Upon authentication of the ISP using the authorized usage certificate for the ISP within the NC, the ISP is free to overwrite the user's initial registration contents user specific ISP account information that the ISP digitally signs. In the preferred embodiment, although the initial registration contents for the ISP on the user's smart card is overwritten during the second phase of user registration, the NC connection information remains the same after registration with the ISP. Although the ISP is allowed to overwrite this data (either the smart card contents or the NVRAM contents) at anytime.
