碩士 === 國立成功大學 === 資訊工程學系碩博士班 === 96 === Wireless sensor networks (WSN) have been comprehensively appied. Aiming at protecting the resource constrained sensors against unauthorized access and providing the data reliability for the authenticated user, we propose the mutual user authentication scheme. The scheme employs the idea underlying LEAP+ (Localized Encryption and Authentication Protocol) to provide the blacklist for authenticated user to detect malicious sensors and make the sensor verify the user efficiently. Comparing with the previous research, our scheme not only achieves the mutual authentication but has the more efficient utilization of sensor’s energy, and further provides the ability to control the access time of each authorized user without the support of server.
