In-band peripheral authentication
First Claim
Patent Images
1. A method, comprising:
- determining an address of a non-media channel at which a peripheral communicatively coupled to a media interface of a host device can be authenticated by the host device;
performing an authentication protocol using the address at which the peripheral can be authenticated;
responsive to the peripheral being authenticated, enabling a full operational mode between the host device and the media interface, wherein the full operational mode includes configuring the media interface to provide content to a component of the peripheral via a media channel and receive input data from another component of the peripheral via the non-media channel; and
responsive to the peripheral not being authenticated, enabling a limited operational mode between the host device and the media interface, wherein the limited operational mode includes limiting the quality of media provided via the media channel of the media interface.

Abstract
This document describes techniques (300, 400) and apparatuses (100, 500, 600, 700) for in-band peripheral authentication. These techniques (300, 400) and apparatuses (100, 500, 600, 700) may communicate via a non-media channel allowing host device (102) to authenticate peripheral (106), enable an enhanced operational mode of the host device (102), and/or provide content configured for the peripheral (106) without the use of out-of-band signaling.

11. A method, comprising:
-
making available an address of a non-media channel to a host device for authentication of a peripheral communicatively coupled to a media interface of the host device; receiving an authentication request from the host device at the address of the non-media channel; communicating an authentication response to the host device via the non-media channel; and receiving, via the media interface of the host device, content configured for the peripheral based on the authentication response communicated to the host device, wherein, responsive to the peripheral being authenticated, a component of the peripheral receives the content via a media channel of the media interface and another component of the peripheral provides input data to the non-media channel of the media interface, and wherein, responsive to the peripheral not being authenticated, the received content is of limited media quality. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A peripheral comprising:
-
an authentication module configured to communicate an authentication response to an authentication request received from a host device via a non-media channel; a communication switch configured to, responsive to connection to the host device, switch the non-media channel from a media interface module of the peripheral to the authentication module of the peripheral to enable authentication of the peripheral; a processor configured to receive, via the media interface of the host device, content configured for the peripheral based on the authentication response communicated to the host device, wherein, responsive to the peripheral being authenticated, a component of the peripheral receives the content via a media channel of the media interface and another component of the peripheral provides input data to a non-media channel of the media interface, and wherein, responsive to the peripheral not being authenticated, the received content is of limited media quality. - View Dependent Claims (21)

20. A peripheral comprising:
-
an authentication module configured to communicate a response to an authentication request received from a host device via a non-media channel, the response useful to authenticate the peripheral; a communication switch configured to, responsive to connection to the host device, switch the non-media channel from a media interface module of the peripheral to the authentication module of the peripheral to enable authentication of the peripheral; and a cable coupled to the peripheral, wherein the communication switch is located within the cable.
