安全的网络编码所面临的挑战和对策

Secure Network Coding:Challenges and Solution

近年来,网络编码以其巧妙的思想展现出生机勃勃的应用前景,但是安全问题一直是其在网络中大规模应用的最大障碍。在现有研究成果上,从网络编码的基本原理出发,按照物理层和网络层两个层面对系统的各个部分进行了更加全方位的安全隐患分析;也给出了针对ACK类和编码类攻击的基于典型集和哈希函数以及马尔可夫模型的防御方法;同时提出了结合利用云计算和网络编码构建计算网络的概念;最后对网络编码的未来研究方向进行了展望。

In recent years,network coding has emerged some exciting future because of its smart technology.However,in order to let network coding become popular in the Internet,its security problem must be solved.Firstly,a wide range of attacks were revealed based on our systematic analysis of the components of these frameworks vulnerabilities.Secondly,this paper gave one proposal for ACK attacks and coding attacks based on Typical Set,Hash Functions and Markov model.Thirdly,one thinking named as Computing Network,which integrates Cloud Computing with Network Coding,was proposed.Finally,the open issues and challenges for network coding referring to both theory and application in near future were proposed.
