Abstract: Sensor nodes in the wireless sensor networks are low cost tiny devices with limited storage, computational capability and power except the sink node. Sink node has no resource limitation. WSNs have wide range of application in the real world problem such as military and civilian domain etc. Energy efficient and security are two major issues of sensor network due to unattended and unprotected. The sensors have limited battery power and low computational capability, thus requires a security mechanism that must be energy efficient. In this paper, we identify the some existing schemes of key management in WSNs. Secure key management has been becoming important critical elements when integrating cryptographic functions into a system. An outline of symmetric and asymmetric key cryptography Key infection schemes are discussed in this paper. As a consequence, we analyze the advantages and disadvantages of current secure key management schemes.
