Typical sensors possess limited computation, energy, computation, memory resources and they are always deployed in a harsh, unattended or hostile environment, so the security issues posed by sensor networks represent a rich and challenging field of research problems. In this study, we probe into various security requirements with regard to Wireless Sensor Network (WSN) and analyze status quo of the security in WSN from three aspects: key management, identity authentication as well as attacks and countermeasures. In conclusion, we point out its development direction based on the analysis and remark of problems remaining unsolved in WSN. ER -
