Abstract:
1. A method for establishing secure wireless communications between two electronic devices, said method comprising: providing a first electronic device which uses a protocol for wireless communications with other devices, said first device containing a Near Field Communication reader/writer; providing a second electronic device which uses the same protocol for wireless communications as the first device, said second device including a Near Field Communication read-only tag which contains secret information about the second electronic device; passing the first device near the second device, such that the first device can read the secret information from the Near Field Communication read-only tag; transmitting the secret information from the second device to the first device in order to initiate the establishment of secure communications; computing and wirelessly transmitting by the first electronic device an authentication certificate which is calculated from the secret information which was read from the Near Field Communication tag; providing a software algorithm on the second electronic device, to detect the transmitted authentication certificate and, upon detection of a valid certificate, cause the second 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.
