Towards Effective Defense Against Pollution Attacks on Network Coding
Network coding provides a promising alternative to the traditional store-and-forward transmission paradigm. For the system using random linear network coding, the adversary could inject corrupted messages into the networks by compromising the network nodes, which is known as the pollution attack. Corrupted messages injected by the adversary, if undetected, could cause a devastating impact to the network performance. To address this issue, a number of pollution attack defense schemes for network coding have been developed in the recent years. The overhead caused by defensive techniques against pollution attacks should be low especially in wireless networks with limited resources.
