Secure Pairing for Wired or Wireless Communications Devices
First Claim
1. A method of pairing a trusted device and a second device, the method comprising:
- receiving a request to pair the second device with a first device;
mutually authenticating the first device and the second device and obtaining from said first device a device identification relating to said first device;
putting the first device into a trusted mode in which it will not engage in a pairing procedure with any device other than the second device;
obtaining a device identification from the trusted device;
comparing the device identification from the trusted device with the device identification obtained in the authenticating step;
if the device identification relating to the first device matches the device identification obtained from the trusted device, determining that the first device is the trusted device and sending a pairing acceptance to the trusted device; and
pairing the trusted device and the second device in response to the receipt of a second pairing acceptance from a user entered into the trusted device.

Abstract
Pairing is achieved between a host communications device and a peripheral communications device, in order to establish an ad hoc wireless or wired network. A device identification, relating uniquely to the peripheral device, is displayed on the host device. In order to accept the pairing, the user confirms that th.—device identification displayed on the host device matches that printed on the peripheral diwice, and then completes the pairing procedure by pressing a key on the peripheral device, or, if Near Field Communication (NFC) techniques are implemented in the devices, by placing the peripheral device in contact with, or sufficiently close to, the host device. Thus, secure pairing is achieved, without requiring a complex user interface on the peripheral device.

24. A peripheral communications device, comprising:
-
means for authenticating the peripheral device to a host device, and transmitting a peripheral device identification to said host device; means for authenticating the said host device to the peripheral device, and receiving said host device identification; means for putting the peripheral device into a trusted mode in which it will not engage in a pairing procedure with any device other than said host device; means for receiving a pairing acceptance input from a user and for confirming pairing with said host device in response to the pairing acceptance input. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37)

38. A host communications device, comprising:
-
means for receiving a request to pair said host device with a peripheral device; means for authenticating the peripheral device and obtaining from said peripheral device a device identification relating to said peripheral device; means for authenticating to the peripheral device and transmitting a host device identification to said peripheral device; means for displaying the device identification relating to said peripheral device; and means for pairing the host and peripheral communications devices in response to the receipt of a pairing confirmation from the peripheral device and a host pairing acceptance from the user entered into the host device. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)

39. A host communications device, comprising:
-
means for receiving a request to pair said host device with a peripheral device; means for authenticating the peripheral device and obtaining from said peripheral device a device identification relating to said peripheral device; means for authenticating to the peripheral device and transmitting a host device identification to said peripheral device; means for obtaining a device identification relating to a trusted device; and means for comparing the device identification relating to the peripheral device and the device identification relating to the trusted device; means for pairing the host and peripheral devices in the event that the device identification relating to the peripheral device and the device identification relating to the trusted device match, and in response to the receipt of a pairing confirmation from the peripheral device.
