MESSAGE TRANSMISSION METHOD USING A PROXY RE-ENCODING TECHNIQUE IN A SENSOR NETWORK FOR REDUCING THE PRODUCTION COST OF A SENSOR NODE

摘要

PURPOSE: A message transmission method using a proxy re-encoding technique in a sensor network is provided to constantly encode sensing data with a public key in each sensor node. ;CONSTITUTION: A sensor node receives the public key of a sensor node(S21). A BS(Base Station) receives a proxy key(S22). The sensor node encodes sensing data with the public key(S23). A server transmits the public key of the server to the BS(S25). The BS changes the sensing data encoded with the public key of the sensor node into sensing data encoded with the public key of the server(S26).;COPYRIGHT KIPO 2011
