UGC^3:一种抵御审查的隐蔽通信方法

UGC^3:a covert communication method defense against censorship

提出了一种基于UGC站点的抗审查通信方法 UGC3,该方法利用已有的网络设施(UGC站点)组成一个全分布式的重叠网络,为了在资源的发布者和接收者之间交换信息,设计了一个高效的资源发现算法来协商资源的发布者和接收者之间的约会地点,利用信息隐藏的方法把目标资源隐藏到掩体媒介,发布到协商好的站点。最后分析了系统的安全性。

A UGC-based covert communication method： UGC3 was presented, which used fixed infrastructure （UGC sites） to form a fully distributed overlay. To exchange information between sender and receiver, an efficient resource discovery algorithm was proposed to negotiate the rendezvous; and then the targeted resource was published in the corresponding user-generated content hosts using information hiding method. Finally, the security properties were discussed
