Abstract

In a network connected to an interactive device and a registration server, a protocol for registering the interactive device with the registration server, including the steps of: installing a secret key and a public unique identifier in non-volatile memory in the interactive device and in a database of the registration server, before the interactive device is connected to the network; then, when the interactive device is connected to the network, authenticating the interactive device at the server by verifying the interactive device'"'"'s encryption, using the secret key, of a challenge message; and finally, if the authentication succeeds, registering the interactive device in the database of the registration server.
