摘要
网络编码是实现匿名通信的有效途径,但在多个单播网络环境下难以提高吞吐量。针对该问题,结合蝶形网络模型,设计一种多播网络下的匿名通信网络编码方案,并基于线性空间原理,采用信息分片和有限域构造方法在Matlab GUI下对方案进行可视化实现。分析结果表明,该方案在提高网络吞吐量的基础上,能够有效抵抗流量分析攻击,实现编码混淆。
Network coding is an efficient way of implementing anonymous communication,but it cannot improve the throughput in multiple unicast networks. Aiming at this problem, this paper proposes an anonymous communication scheme under multicast network, combined with the butterfly network model. It gives the visual implementation in Matlab GUI by using the principle of linear space, information division and finite field construction in Matlab GUI platform. Analysis result shows that, this scheme not only improves the throughput, but also resists flow analysis attack. It can realize encoding confusion.
