Secured communication for local area network

摘要

A method and system for distributed security for a plurality of devices in a communication network, each of the devices being responsible for generating, distributing and controlling its own keys for access to the communication network and using the keys to establish a trusted network, each device's membership to the communication network being checked periodically by other devices by using a challenge response protocol to establish which devices arc allowed access to the communication network and the trusted network.

1. A method, by a security manager in a first ad hoc network, of facilitating communications between a first device located in the first ad-hoc network and a second device located in a second ad-hoc network, said method comprising:
sending the first device a first group key; receiving, via a relay channel between said first ad-hoc network and said second ad-hoc network, a request for authentication from the second device, wherein said first ad-hoc network includes a first plurality of devices, said second ad-hoc network includes a second plurality of devices, and the relay channel is established using first and second transceivers, the first transceiver being in said first ad-hoc network, and the second transceiver being in said second ad-hoc network; and sending the second device the first group key.
