现有安全重编程方案无法对基于网络编码技术的新一代重编程协议提供安全保护。文章针对上述缺陷,提出了一种抗污染攻击(pollution attacks)的安全重编程方法PRMR(Pollution-ResistantMethod for Reprogramm ing)。该方法利用组合技术实现污染攻击下的编码包正常译码;并通过邻居分类系统隔离污染者(polluters)。TOSSIM仿真实验表明在一个6度的无线传感器网络中,当20%的节点为污染者时,使用PRMR方法,重编程数据分发完成时间仅是无攻击情况下的2倍;每页也仅比无攻击情况下多执行70%的译码。
Existing security reprogramming solutions fail to provide security for next-generation reprogramming protocols based on network coding technology. In view of the above defects, this paper proposes a PRMR (Pollution-Resistant Method for Reprogramming) method for reprogramming against pollution attacks. This method uses a combination of techniques to achieve normal decoding of encoded packets under pollution attack and isolates polluters through a neighbor classification system. TOSSIM simulation results show that when a 20% node is a polluter in a 6-degree wireless sensor network, the PRMR method is used. The reprogramming data delivery time is only twice as long as in the case of no attack. Perform 70% more decoding under attack conditions.
