A Study on Key Management Issues in Wireless Sensor Network

Madhumathi Rajesh


Wireless sensor networks (WSN) consist of nodes with limited power capabilities and low processing, communicating and
storage ability. Many applications require WSNs to exchange sensitive information or contain feedback processes that have high
reliability requirements, and they require a high level of security to succeed. The WSN nodes are often placed in hostile or adverse
environment and their security concerns become a challenging issue. WSNs nodes are resource constrained and hence incorporating
traditional security methods involving large computation overheads are not feasible. Key management is a fundamental part for any
secure communication in WSNs. Many key establishment techniques have come up to address the tradeoffs between limited memory
and security but choosing an effective scheme is debatable. In this paper, I am providing a survey of various key management schemes
in WSNs. Choosing a key management scheme depends upon the target applications requirements and the resource of the sensor
