| Abstract(in English) | Requirements of smartphone users shift from the quality of service, i.e., throughput, to the quality of applications . Moreover the communication traffic is always encrypted in order to protect the personal information. Given the facts, it is important for the network operators to control the encrypted traffic to satisfy the requirements of smartphone users. In this paper, we propose a new scheme to identify applications on smartphone by analyzing the characteristics of encrypted traffic without packets inspection. Our proposed scheme represents the time-series data of encrypted traffic as a probabilistic states transition model. Moreover the model enables to estimate the transition timing of applications from the time-series data and then enables to identify the applications accurately. We evaluate the effectiveness of our proposed scheme by analyzing the traffic data that a smartphone user watches some movies and browses some web pages. |
