Guo Li · Journal of Communications · 2012
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 dis-covery algorithm was proposed to negotiate the rendezvous;and then the targeted resource was published in the corre-sponding user-generated content hosts using information hiding method.Finally,the security properties were discussed.
