    Abstract

    In order to mitigate privacy violations in Wireless Access in Vehicular Environment (WAVE) technology, the WAVE standards prescribe pseudonymity as the primary solution. However, there are hidden complexities and costs that are incurred by the solution for non-safety, IP-based communications. Specifically, the re-addressing across the protocol stack triggered by pseudonym changes interact complicatedly with TCP/IP protocol components such as Multicast Listener Discovery, Duplicate Address Detection, TCP retransmission, and the TCP/IP networking constructs in operating systems. Unless carefully handled, they can compromise the IP communication performance or the privacy property arising from the pseudonymity. In this paper, we illustrate these points with an emphasis on connection management, through a Multipath TCP (MPTCP)-based implementation.

    Bibliographical note

    Funding Information:
    Maintaining IP session connectivity across pseudonym changes is easier said than done. In this paper, we show that we can build a solution around the MPTCP protocol. MPTCP or not, however, we find that there are quite a few pitfalls to avoid, as many TCP/IP networking components should be involved: IP multicast, DAD, TCP retransmission, and the kernel networking platform, among others. Unless carefully handled, they can compromise the IP communication performance or the privacy property arising from the pseudonymity. We hope that our experience will provide guidance to future solutions for pseudonymity management in the WAVE environment.
