Abstract(in English) In network management, application identification of traffic is important. However, since encrypted traffic has been increasing in recent years, it is becoming difficult to identify the kind of application by methods proposed so far. In application identification, encryption is one of serious factors to degrade the accuracy of identification because it is so hard to infer the original (unencrypted) traffic from the encrypted one. Our research goal is to increase the accuracy of application identification even if there is encrypted traffic. In this paper, we numerically analyze how the characteristics of original traffic are changed by encryption. Specifically, we monitor packets of the same flow, at the points of before/after encryption. We then collect statistical information on monitored flows, and numerically analyze how this information has been changed by encryption. By applying regression analysis, we show that we can estimate the statistical characteristics of original traffic from measured encrypted traffic.
