防窃听和污染攻击的安全网络编码

搭线窃听和污染攻击是安全攻击中的2种重要手段。研究表明,网络编码自身的数据融合特性能够达到一定的安全传输效果。针对污染攻击和搭线窃听攻击,在此提出一种能够防御全能窃听和污染攻击的安全网络编码。在攻击者具有全能窃听能力以及污染部分链路,该方案通过对传输的信息进行哈希达到了防污染攻击的效果,对全局编码向量进行加密实现了防污染攻击,该方案适用于攻击者窃听能力较强并且具有污染攻击威胁的网络中。分析结果表明,该方案是有效的。

Secure network coding against eavesdropping and pollution attack

Wiretapping and pollution attack are two important means of security attack. The research shows that the of data fusion characteristics in network coding can reach the safety transmission. Aiming at the pollution attack and wiretapping attack, a secure network coding which can prevent all-round eavesdropping and pollution attacks is proposed in this paper. When the at-tacker has the ability of all-round eavesdropping and partial link pollution,the Hash is adopted in the scheme for transmitted in-formation and the global coding vector encryption is used to prevent the almighty eavesdropping and pollution attack. The scheme is suitable for the networks that the attacker has strong eavesdropping and pollution attack ability. The analysis results show this scheme is effective.
