Premakumar M. N., Ramesh S . A Research Study on different Key Management Strategies for Large Scale WSNs. Communications on Applied Electronics. 7, 24 ( Dec 2018), 1-10. DOI=10.5120/cae2018652801
A wireless sensor network technology is immensely utilizing in multiple fields, for example; physical environment monitoring, surveillance systems, object tracking systems, robotic systems and many more. Usually, wireless sensor nodes are deployed in remote or hostile environments, and such sensors are vulnerable to compromise different attacks; therefore, a suitable and efficient key management scheme is essential at this point. Recently, different key management approaches are proposed by different researchers to address security challenges, especially for WSNs. Since key management is a core scheme to ensure security for network resources along with solving the problem of key generation, distribution, and secret key management. Hence, in this investigational study have to provide a detailed study on reliable key management techniques which are playing a vital role in large-scale WSNs. This study classifying the key management scheme into Asymmetric based and Symmetric based key management schemes and highlighting their functionalities by evaluating performance parameters. In the beginning, the study defines a workflow of the key management system followed by life cycle. Additionally, have briefly discussing popular key-management algorithmic approaches their applications and limitations.
