Research On The Implementation Mechanism Of Anonymous Linear Network Coding

With the development of science and technology, computer network has become a significant role in our daily life. With the expansion of information and network resource demand, the low transmission efficiency of the original communication technology exposed. Unlike the traditional routing method, network coding can achieve the theoretical maximum value of the channel capacity of multicast network, so as to achieve more efficient use of network resources. Network coding is considered to be a promising research direction.Privacy security has always been a hot topic in the field of network. The natural mix of network coding can effectively make anonymous communication, so as to protect the privacy of communication. In recent years, researchers have in-depth research about anonymous network coding and put forward a variety of effective anonymity schemes. However, the vast majority of research is only limited on the theoretical level. How to achieve feasible anonymous network coding scheme has become a crucial problem. To solve this problem, the paper has done the following work:In view of the effect of network coding in anonymous communication. In this paper, we give an in-depth analysis about several existing anonymous network coding schemes. According to the present anonymous linear network coding strategy only in the case of multiple unicast network can not improve the throughput, this paper design a multicast anonymous linear network coding scheme combined with classic "butterfly network". The scheme not only improves the throughput, but also resists flow analysis attack. We gives a visual implementation by using information division and finite field construction in MATLAB GUI platform.In practical application, the innovative network architecture, software defined network (SDN) has been paid attention worldwidely in the IT field, compared with the traditional network has a potential advantage. Therefore, the use of SDN to achieve specific network coding strategy will be of great value. In this paper, we show the specific process of linear network encoding by using Mininet-a SDN network builder in Linux.
