%X Wireless sensor network is a kind of Ad hoc network consisted of hundreds or thousands or more of micro sensor nodes,which has been deployed for many practical applications,including military sensing and tracking,envi- ronment and security monitoring,equipment and human monitoring and tracking,etc.Due to limitations of power, computation capability and storage resources,security of wireless sensor networks has received considerable attention. In order to construct a secure network,it is an important challenge to find out suitable key establishment,distribution and encryption schemes for wireless sensor networks.The paper argues about the security concerns firstly and then surveys the research of key system in wireless sensor network.Finally it presents an efficient key system scheme which is based on identity encryption algorithm for wireless sensor network.Simulation results among our scheme and other traditional key system schemes suggest that our scheme is feasible in wireless sensor network.
