Abstract

Devices and methods use close range communication links, such as near field communication (NFC) protocol links, to enable users to authenticate mobile devices to one another to create or expand secure multicast groups. Once the two or more devices establish a close range communication peer-to-peer link the devices exchange multicast group communication data sufficient to permit the devices to receive or send multicast messages. Long range wireless or wired network communication links are then used for multicast message communications. Proximity limits of the close range communication P2P link enables mutual trust to be presumed among devices, reducing the need for security and authentication signaling. The limited range of close range communication P2P links renders multicast groups established in this manner less vulnerable to eavesdropping and intrusion. Embodiments enable users to initiate secure multicast group participation merely by bringing two or more devices into close proximity.

Description

[0001] Related applications [0002] This application claims Serial No. 60 / 891,231, filed February 23, 2007, entitled "Method and Apparatus to Create Multi-Cast Groups Based on Proximity" Priority to United States Provisional Patent Application, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates generally to computer network communications and, more specifically, to creating multicast groups based on proximity. Background technique [0004] As mobile devices and consumer electronic devices target integrated marketing, there is an increasing interest in multicast communication technologies. In a multicast group, multiple participants are collectively linked into an inter-network where the participants send and receive communications with each other. Such networks have a variety of useful applications, from business collaboration to interactive gaming. Multicast groups are not without their dangers, how...
