POINT-TO-POINT COMMUNICATION METHOD IN A WIRELESS SENSOR NETWORK AND METHODS OF DRIVING COORDINATORS AND COMMUNICATION DEVICES IN THE WIRELESS SENSOR NETWORK

摘要

The present invention relates to a point-to-point communication method that performs mutual authentication and creates link keys without using a master key. The point-to-point communication method can include authentication by exchanging authentication information between a first node and a second node from among the plural nodes; and having each of the first node and the second node create a link key, after the authentication is completed. During the authentication, the authentication information uses a secret key of a corresponding coordinator (node).
