A Novel Authentication Scheme Against Node Captured Attack in WSN for Healthcare Scene

Over the past decades, Wireless Sensor Networks play a significant role in IoT. Several applications in wide range of industries have attempted to apply this hot technology, including healthcare. However, in current WSN for daily applications, wireless sensors are deployed in easily-touched places in which the malicious user can capture those nodes much easier than before. Especially in medical or healthcare environment, an urgent need of a secure WSN access scheme is requested, especially for the resistant of node capturing attack. This paper proposes a novel authentication information exchanging scheme against node capturing attack in WSN. This paper describes the idea behind this novel scheme, which comes from the association scheme of local sensor nodes. This scheme asks all sensor nodes should periodically contact with GWN and meanwhile execute authentication information exchanging scheme for resist security risk from one node captured by a sophisticated hanker. This paper gives an early study and provides detail discussion of this scheme and validates it in the future.
