Abstract (in Japanese) (See Japanese page) 
(in English) In network management, identification of traffic type is important. However encrypted traffic has been increasing (in recent year), and so it is becoming difficult to identify the traffic type. The identification of application from the encrypted traffic is generally difficult, and so it is expected that existing method to identify the application can’t operate accurately. One of method to overcome this problem is to detect whether traffic is encrypted or not, and identification is operated for traffic remove encryption overhead from encrypted traffic. In this paper, we study the method to detect encrypted traffic early. We analyze statistical information of encrypted traffic and plaintext traffic. We show statistical information which has remarkable characteristics in each traffic.We then propose the method to detect encrypted traffic by using the information.
