An Efficient Authentication Scheme Against Pollution Attacks in Network Coding
Xiaoqin Luo · Journal of Fujian Normal University · 2014
In the progress of wireless network,attackers can pollute the whole network through substituting the messages when capturing the nodes,in this case,the security of the network may decrease obviously. Systems exploiting network coding to increase their throughput but exploiting network coding directly can not defense efficiently suffer greatly from pollution attacks. It proposed a secure scheme to address pollution attacks by adopting linear network coding techniques where the source multicast messages to the destination. It has three merits: A trusted authority generate private key by exploiting chinese remainder theorem. Allowing intermediate nodes and destinations verify the messages' origin and its integrity with their private keys without decoding. High security,it discusses the efficiency of the proposed scheme from computational cost and storage cost.
