CROSS CERTIFICATION SYSTEM BETWEEN NODE AND SINK AND METHOD IN SENSOR NETWORK PERFORMING AUTHENTICATION BETWEEN SINK AND NODE THE PUBLIC KEY IS USED

摘要

PURPOSE: In the sensor network, by confirming the public key used in the ash authentication procedure of node as the signature of sink the cross certification system between node and sink and method minimize the time to be required to the public key calculation.;CONSTITUTION: The node(30) requests authentication or reauthorization among one or more sink as a one. According to the first sink(11) is the authentication request from node, the authentication of node is requested as the base station. The first sink certifies node by receiving a message the node authentication information from the base station.;COPYRIGHT KIPO 2011
