A New Investigation Approach for Tracing Source IP in DDoS attack from Proxy Server

摘要

In this paper, we proposed an investigation approach to trace the source IP address hiding which use proxy servers, and reduce the steps of the classical investigation method. Furthermore, it does not need to execute search and seizure to perpetrators, but it still obtains the key digital evidences from a third party. The obtained key digital evidences have the same probative force with the classical investigation, and it can used to discover the perpetrator whether he hides his IP address and the criminal acts. In this paper, first, we proposed an approach that makes the case related people not be examined, searched and seized; second, the true criminal cannot evade punishments and trial by hiding his IP address, so the investigation procedure is hard to execute; third, the investigation approach we proposed will reduce wasting judicial resources and protect human rights effectively.
