A survey on proficient techniques to mitigate Clone attack in wireless sensor networks

Due to open deployment of sensor nodes in hostile environment and lack of physical shielding, sensor networks are exposed to different types of physical threats including Clone attack where an adversary physically compromises a node, extract all the credentials such as keys, identity and stored codes, make hardware replicas with the captured information and introduce them at specified positions in the network. Replica detection has become an important and challenging issue in the field of security. This paper surveys the existing schemes for clone attack detection. To conclude the paper, a comparison is shown of all the existing techniques in the literature.
