Cookie based online tracing method for cyberlockers resource

Cyberlockers have recently become an Internet-based agent of information dissemination. In light of the non-negligible fraction accounted by the traffic flows originating from cyberlocks, it is necessary to trace them for net-work security. An efficient and scalable cookie based online cyberlockers resource tracing method was proposed, called CookieTracing. It can achieve an efficient association between cyberlockers resource and its download redirect chain by construction of index table between cookie and HTTP sessions in massive HTTP sessions. Meanwhile, through cumula-tive hash algorithm, it can speed up the validation of tracing results. Experimental results show that this method performs good efficiency and scalability.
