Abstract:
1. A method of providing configuration parameters to an uninitialized client in a client-server broadcast network, said method comprising: receiving at a proxy connected to said broadcast network a local broadcast communication initiated by said uninitialized client and intended for reception at a trusted key source, wherein said local broadcast communication includes the hardware address for said uninitialized client and wherein said proxy operates as a security intermediary between said uninitialized client and said trusted key source; recording said hardware address for said uninitialized client at said proxy; adding at said proxy authorization data to said received local broadcast communication when said received local broadcast communication does not include said authorization data; forwarding said received local broadcast communication from said proxy to said trusted key source; utilizing said trusted key source to perform a mutual authentication with said unitialized client; generating at said trusted key source a ticket which includes said hardware address for said uninitialized client to said proxy; forwarding said ticket, upon successful completion of the mutual authentication, from said trusted key source to said uninitialized client via said client-server broadcast network; and employing said ticket to obtain a network address from said server via an authenticated address assignment protocol.
