Abstract

An apparatus is described herein. The apparatus includes a controller and a proxy entity. The controller is to detect a peripheral device and authenticate the peripheral device according to a first protocol. The proxy entity that is to configure the peripheral device in an operable protocol in response to the authentication.

First claim

What is claimed is:

1 . An apparatus for authentication of a multiple protocol connection, comprising:
a controller that is to detect a peripheral device and authenticate the peripheral device according to a first protocol; and a proxy entity that is to configure the peripheral device in an operable protocol in response to the authentication with a host.

2 . The apparatus of claim 1 , wherein the host and the peripheral device are coupled via a multi-protocol connection.

3 . The apparatus of claim 1 , wherein the host and the device are peripheral coupled via a USB Type-C connection.

4 . The apparatus of claim 1 , wherein the first protocol is a Universal Serial Bus 2.0 protocol.

5 . The apparatus of claim 1 , wherein the first protocol is a Universal Serial Bus Power Delivery protocol.

6 . The apparatus of claim 1 , wherein the proxy entity is to translate an authentication message across multiple protocols to traverse a USB hub that is coupled with the host device and the peripheral device.

7 . The apparatus of claim 1 , wherein the authentication is performed via a mutual authentication.

8 . The apparatus of claim 1 , wherein the authentication is performed via a public key infrastructure.

9 . The apparatus of claim 1 , wherein the host communicates with the peripheral device based on a host policy.

10 . The apparatus of claim 9 , wherein the host policy prevents the presence of the peripheral device from becoming visible to an operating system of the host.

11 . The apparatus of claim 1 , wherein the device, based on its policy, is to communicate with the host.

12 . A method for authentication of a multiple protocol connection, comprising:
determining a first domain based on a device configuration; authenticating, by a host, a device in the first domain; reconfiguring the device to operate in a second domain based on the authentication of the device in the first domain.

13 . The method of claim 12 , comprising determining the first domain by detecting the device configuration using a proxy entity.

14 . The method of claim 12 , wherein the host and the device are coupled via a multi-domain connection.

15 . The method of claim 12 , wherein the host and the device are coupled via a USB Type-C connection.

16 . The method of claim 12 , wherein the first domain is a Universal Serial Bus 2.0 protocol.

17 . The method of claim 12 , wherein the first domain is Universal Serial Bus Power Delivery protocol.

18 . A system for authentication of a multiple protocol connection, comprising:
a host device; a peripheral device, wherein the host device and the peripheral device are to mutually authenticate in a first domain; and a controller that is to configure the peripheral device in an operable domain in response to the authentication.

19 . The system of claim 18 , wherein the host and the peripheral device are coupled via a multi-domain connection.

20 . The system of claim 18 , wherein the host and the device are peripheral coupled via a USB Type-C connection.

21 . The system of claim 18 , wherein the first domain is a Universal Serial Bus 2.0 domain.

22 . The system of claim 18 , wherein the first domain is a Universal Serial Bus Power Delivery domain.

23 . The system of claim 18 , wherein the proxy entity is to translate an authentication message across multiple domains to traverse a USB hub that is coupled with the host device and the peripheral device.

24 . The system of claim 18 , wherein the authentication is performed via a public key infrastructure.

25 . The system of claim 18 , wherein in response to the authentication, the peripheral device is initialized.
