Abstract:

With wireless sensor networks＇ application in military and other data-sensitive fields, their security becomes a hot topic. In this paper, the securi ty objective and implementation constraints of wireless sensor networks are introduced. Then the attacks which wireless sensor networks may suffer and the main defense means are summarized. Various security technologies are analyzed. Finally the future security research of wireless sensor networks are e xplored.
