Abstract(in English) | This paper proposes a criterion of Encryption Level focusing on ranges of encryption, as a basis for designing a policy which specifies the degree of protection of communication data. Then, this paper also proposes an Encryption Level classification method by computing randomness of communication data. This method is based on observation that randomness of packet payloads in encrypted traffic is much higher than that in plain traffic, and therefore the method is application agnostic. Evaluation experiments using real traffic data shows the effectiveness of the proposed method. |
