Abstract:
1. A method for providing a secure peer-to-peer communication comprising: establishing a first wireless communication link between a first device and an access point according to a first communication protocol for a wireless local area network to transfer data between the first device and the access point, wherein the first device and the access point are configured for operation within the wireless local area network; establishing a second wireless communication link between the first device and a second device according to a second communication protocol for a personal area network, in which the second wireless communication link is a direct peer-to-peer communication link that does not utilize the access point; engaging in a pairing exchange process between the first and second devices over the second wireless communication link using the second communication protocol to generate a link key and an associated encryption key, wherein the link key is generated with an input string that includes at least a portion of a media access control (MAC) address; and utilizing the link key and the associated encryption key to establish a third wireless communication link according to a third communication protocol between the first device and the second device, in which the third wireless communication link is also a direct peer-to-peer communication link, but the third communication protocol is different from the second communication protocol, and in which the data intended for transfer between the first and second devices over the second wireless communication link is instead encrypted using the encryption key and transferred over the third wireless communication link.
