| 1 | 安全网络编码综述显示文摘对安全网络编码的研究和发展作了综述,在介绍网络编码核心思想的基础上,详细阐述了通信网络中各种常见的攻击,并给出了对抗这些攻击所构建的安全网络编码协议,着重展示了结合网络编码的自身特点而设计的对抗各种攻击的方案;进而对安全网络编码与网络容量及网络开销之间的关系作了简要介绍;最后对安全网络编码理论的发展趋势和应用前景作了分析和展望。结合网络编码的自身特征,设计消耗资源少,对信道容量利用率高的安全网络编码将是一个发展趋势。 | 曹张华 唐元生 | 2010 | 计算机应用2010,30,2: | 11 |
| 2 | Anti-eavesdropping Network Coding Algorithm Based on T-N Threshold显示文摘Catering to the public nature of Ad hoc network in open channel and data communication being easily eavesdropped,this paper proposed an antieavesdropping algorithm which is based on network coding.The algorithm is based on the RSA signature algorithm introducing the timestamp and homomorphic mechanism to detect tampering and replay attacks,as the basis for calculating safety,being used as one of measurement indicators in router by node safety to establish t pieces of routing entry.It generates encoding vectors by introducing the random number when the source node is encoded and the random number will be divided into n pieces.As long as the sink node receives t pieces of fragments,we can restore the original encoding vector and decode it.If the eavesdropper wiretaps are less than t,they can not get any meaningful information.It is designed for increasing the number of linearly independent coded packets.It can improve the decoding efficiency by adopting generational grouping strategy while being encoded.Simulation and theoretical analysis shows that the anti-eavesdropping algorithm based on network coding improves network performance and security by coding gain. | LIU Jun YANG Jingyu CHENG Zijing WANG Mengyuan | 2017 | Chinese Journal of Electronics2017,26,2: | 2 |
| 3 | 防窃听和污染攻击的安全网络编码显示文摘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。 | 马亚蕾 王改宁 | 2014 | 现代电子技术2014,37,10: | 0 |
