Key management has remained a challenging issue in Wireless Sensor Networks (WSNs) due to the constraints of sensor node resources. Various key management schemes that trade off security and operational requirements have been proposed in recent years. Wireless sensor networks with low cost, low energy consumption and high utilization are becoming practically feasible through recent advances in wireless communication and microelectronics. The security concerns of the sensor nodes becomes a challenging issue since the nodes are often placed in hostile or adverse environment. Key management is a critical security service for communication in WSNs. The key management system should be substantially secure, robust and efficient for a secure communication protocol. Many key establishment techniques have come up to address the tradeoffs between limited memory and security but choosing an effective scheme is debatable.
