ABSTRACT:
All network computer client device (NC) manufacturers' authorizations to connect to specific internet service providers (ISPs) are maintained in a central database associated with a relationship server. The relationship server issues digital certificates which associate various ISPs to their respective public keys. Each ISP is assigned a unique enterprise identification number by the relationship server. To authorize a specific ISP, the manufacturer begins with the relationship server's ISP certificate. The manufacturer computes and appends its own digital signature for the relationship server's ISP certificate, thereby creating an ISP usage certificate valid for its NCs which it sends back to the relationship server. Upon first powering on, each NC dials the relationship server and transmits its manufacturer identification number. The relationship server uses the manufacturer identification number to find the ISP usage certificates corresponding to the NC manufacturer. The relationship server then sends to the NC the ISP usage certificate corresponding to the enterprise identification number, or corresponding to the user's selection if no enterprise identification number on the smart card is established. The NC performs a cryptographic verification of the ISP usage certificate using the manufacturer's public key which is permanently stored in the NC in read only memory. Only if the verification of the ISP usage certificate is successful, thus indicating that the ISP usage certificate is signed by the manufacturer does the NC then attempts to connect to the ISP. When an ISP and manufacturer terminate an agreement, the relationship server disables the ISP's managed access software; when the NC's attempt to connect to the ISP fails, the NC then dials the relationship server to receive a new ISP usage certificate.
