DEVICE AUTHENTICATION

摘要

A method, system and corresponding components to authenticate a host device are disclosed. In one aspect, an established process for coupling a module and a host device is used, the established process allowing the host device and module to mutually authenticate each other. A third entity, an authentication server, is then used to authenticate the module using an identification stored in the module such as a private key, or other ID information. By virtue of remotely authenticating the module, and the mutual authentication between the module and the host device, the authentication server is able to trust the host device and proceed to a next step, such as providing access rights to the host device to access content.

1. A method for authenticating a host device in a television receiver system for providing media content to a user, wherein the system comprises:
a host device to be authenticated, the host device being configured to receive media content via broadcast and/or via the internet; and a removable authentication module coupled to the host by an interface, the host and authentication module being configured to communicate over the interface and to perform mutual authentication of the host device and authentication module according to a particular protocol; wherein at least one of the host device and the removable authentication module are configured to communicate with an authentication server; the method comprising:
issuing a request to the authentication server to perform authentication of the authentication module;performing authentication of the authentication module by exchanging data between the authentication server and the authentication module; wherein the host device is deemed to be authenticated when the authentication module and host are successfully mutually authenticated and the authentication module is successfully authenticated by the authentication server.
