A strategy of network coding against wiretapping attack based on network segmentation

Abstract

Compared with the traditional route-based network theory, there are lots of characteristics and advantages of network coding technology in Wireless Sensor Networks (WSN). At the same time, it is facing a variety of security threats, especially wiretapping Attack. Existing network coding security policies are mostly focused on building secure coding strategy, compared to the secure coding design strategies, security topology design strategies are much less. In this paper, we propose a weakly-secure network topology algorithm based on network segmentation. Simulations show that the proposed strategy can prevent cooperative eavesdroppers from acquiring any useful information transmitted from source node to sink node. © 2014 Springer International Publishing Switzerland.
