Abstract:
Recent mobile terminals have multiple interfaces, such as 4G and wireless local area network (WLAN). In order to use those interfaces at the same time, multipath transmission control protocol (MPTCP) is introduced in several operating systems. 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, in our previous paper, a new method to improve privacy against eavesdropping using the data dispersion by exploiting the multipath nature of MPTCP. One feature of the proposed method is to realize that an attacker cannot observe data on any path, even if he observes traffic over only a part of paths. Another feature is to use data scrambling instead of ciphering. In this paper, we present the design of this method and the results of performance evaluation. Besides, we discuss how to implement it inside the Linux operating system kernel, using a kernel debugging mechanism called JProbe.
