In this paper we present a possible extension of the proposed Mobile
IP and route optimization protocols, the Non-Disclosure
Method (NDM). It prevents the tracking of user movements by
third parties and gives mobile users control over the revelation of
their location information, according to their personal security
demands.
We give an overview on Mobile IP protocols and briefly
discuss these protocols in terms of security issues. We show
that confidential location management in Mobile IP is an
unsolved problem. Then we propose our method for
providing untraceable communications in packet-oriented mobile networks.
NDM is based on the idea of mixes, which
has been suggested by Chaum for hiding the originator addresses of electronic
mails. Our algorithm prevents the linkability of sender and recipient addresses
in Mobile IP, can be easily adopted to other mobility
supporting networks as well. We conclude our paper with performance
aspects, discussing the trade-off between the level of
security provided and the costs of NDM in terms of increased
packet transmission delays. For this purpose, we present
a new modelling approach for Internet connections, which is
based on empirically derived packet delay distributions and
their analytical description. Our results show that the
overhead for confidential location management is not
as critical as might be expected, and that a considerable
delay reduction compared to mixes can be achieved.
