Multiple near field communication tags in a pairing domain
First Claim
1. A method for establishing a secure wireless communications network between electronic devices, said method comprising:
- providing a plurality of electronic devices which use a common protocol for wireless communications with other devices, each device containing a Near Field Communication reader/writer;
providing a master electronic device which is capable of controlling other devices in the network;
providing a plurality of Near Field Communication read-only tags within a defined geographic space, where the defined geographic space is a vehicle which includes an entertainment system, and each tag of the plurality of Near Field Communication read-only tags is placed at a different seating location within the vehicle, and where each tag contains secret information about the master electronic device;
passing each electronic device which is intended to be added to the network near one of the Near Field Communication read-only tags;
computing and wirelessly transmitting an authentication certificate from each device which is calculated from the secret information which was read from a Near Field Communication tag;
using the transmitted authentication certificate, if valid, to trigger the master electronic device to temporarily switch from a non-discoverable mode to a discoverable mode; and
completing the establishment of communications by exchanging additional data as required by the wireless communications protocol being used.

Abstract
A system and method for simply and securely pairing multiple Bluetooth or other wireless electronic devices in a network. Multiple Near Field Communication (NFC) read-only tags are places in a vehicle or other defined space, such that users of NFC-enabled electronic devices can pass their device near one of the NFC tags, which then transfers encryption key data to the user'"'"'s device, allowing that device to be automatically joined to a small, secure wireless network. Various embodiments are disclosed for establishing and controlling the network, and applications are suggested for using the ad-hoc network—such as for the control of a vehicle'"'"'s entertainment system.

10. A system for establishing a secure wireless communications network between electronic devices, said system comprising:
-
a plurality of electronic devices which use a common protocol for wireless communications with other devices, each device containing a Near Field Communication reader/writer; a master electronic device which is capable of controlling other devices in a network; a plurality of Near Field Communication read-only tags within a defined geographic space, where the defined geographic space is a vehicle, and each tag of the plurality of Near Field Communication read-only tags is placed at a different seating location within the vehicle, and where each tag contains secret information about the master electronic device, wherein each device in the plurality of electronic devices includes a software algorithm for computing and wirelessly transmitting an authentication certificate that is calculated from the secret information which was read from a Near Field Communication tag; and a triggering mechanism that causes the master electronic device to temporarily switch from a non-discoverable mode to a discoverable mode, wherein the master electronic device includes a software algorithm for detecting a transmitted authentication certificate and, upon detection of a valid certificate, cause the master electronic device to temporarily switch from the non-discoverable mode to the discoverable mode. - View Dependent Claims (11, 12, 13, 14, 15)
