Improvement of the Security Against Node Capture Attacks Using Dispersed Data Transmission for Wireless Sensor Networks

Node capture attacks are one prospective kind of attack on WSNs. To prevent node capture attacks, we have proposed secure decentralized data transfer against node capture attacks, previously. In this proposed method, the existence of multiple paths was assumed to be the case. In this paper, we have proposed taking into account the multipath routing of our previously proposed method. To make multiple paths fit our previously proposed method, we have modified ATR (Augmented Tree Based Routing). We have implemented our proposed method in a network simulator. We have conducted simulation experiments. The results show that our previously proposed method is effective in both cases in which the network size is small or large.
