ECAWSN: eliminating compromised node with the help of auxiliary nodes in wireless sensor network

摘要

Network without security becomes a threat to integrity and authentication. Sensor network consists of cheap, tiny devices which can be incarcerated to provide erroneous data to the concerned authority. Hence integrity and authentication becomes a foremost concern. This paper utilises both preventive and detection measures to cope with different kinds of attacks in the network layer. In this paper, pairwise key is being generated utilising auxiliary nodes. The paper enhances security of the network against Sybil attack, Sinkhole attack and Wormhole attack.
