摘要
网络编码能够达到网络的最大理论容量,由于中间节点的可编码性,使得恶意节点有更多的机会对网络进行污染攻击,扩大了污染信息在网络中蔓延的程度,最终导致网络瘫痪。简要介绍了网络编码和污染攻击的概念,针对网络中采用了网络编码的抵抗污染攻击的研究方案进行了论述,并分别从3个不同的角度对已有研究成果进行了对比和分析。最后,讨论了网络编码中污染攻击研究仍存在的问题,提出了对未来的展望。
Network coding can improve the network performance significantly. However, as intermediate nodes can code together the packets they receive, the polluted information can spread to the whole network more rapidly leading to paralysis of the whole network. Thus, networks involving network coding are vulnerable to the pollution attack. Network coding and pollution attacks are summarized briefly. The research work on anti-pollution attack in network coding is reviewed and some related important schemes are discussed briefly. Finally, the remaining problem is pointed out.
