【摘要】 Kad网络中存在数百万的共享资源,而其中有相当一部分可被评定为敏感资源。首先用我们的Kad网络采集器:Rainbow对节点拥有的文件资源进行探测;然后对节点资源和敏感资源进行相关统计分析。我们发现:1)只有3.09%的节点拥有资源;2)文件长度和文件流行度都近似符合Zipf分布;3)利用同一个file-content-hash的多个文件名的共现词可以更准确地进行敏感判别;4)敏感资源只占随机样本的6.34%,且敏感资源中56%为video文件。
【Abstract】 There are millions of shared resources in Kad network,and a considerable part of them can be rated as sensitive resources.Firstly,the file resources of peers are measured using our Kad network crawler:Rainbow,then, those resources and sensitive resources are statistically analyzed.We find that:1) only 3.09 percent of peers hold resource;2) the size and popularity of files approximately correspond to Zipf distribution;3) the sensitivity of files can be judged more accurately using co-occurrence-words in multiple filenames corresponding to the same file-content-hash;4) sensitive resources only occupy 6.34 percent of random sample,and 56 percent of sensitive resources are video files.
