Abstract:
In order to utilize multiple communication interfaces installed mobile terminals, Multipath Transmission Control Protocol (MPTCP) has been introduced recently. It can establish an MPTCP connection that transmits data segments over the multiple interfaces, such as 4G and Wireless Local Area Network (WLAN), in parallel. However, it is possible that some interfaces are connected to untrusted networks and that data transferred over them is observed in an unauthorized way. In order to avoid this situation, we proposed a method to improve privacy against eavesdropping using the data dispersion by exploiting the multipath nature of MPTCP in our previous papers. The proposed method takes an approach that, if an attacker cannot observe the data on every path, he/she cannot observe the traffic on any path. The fundamental techniques of this method is a per-byte data scrambling and path dispersion. In this paper, we present the result of implementing the proposed method within the Linux operating system and its performance evaluation in more detail than our former papers.
