Abstract

There have been reports of systems that would monitor the wireless connections of passengers at Canadian airports [CNBC]. We can assume that these are either fragments or trial runs of a wider system that would attempt to monitor Internet users as they roam through wireless access points and other temporary network attachments. We can also assume that privacy-conscious users will attempt to evade this monitoring -- for example, by ensuring that low-level identifiers such as link-layer addresses are "randomized", so that the devices do not broadcast the same unique identifier in every location that they visit.

                   Anonymity Profiles for DHCP Clients

Abstract

   Some DHCP options carry unique identifiers.  These identifiers can    enable device tracking even if the device administrator takes care of    randomizing other potential identifications like link-layer addresses    or IPv6 addresses.  The anonymity profiles are designed for clients    that wish to remain anonymous to the visited network.  The profiles    provide guidelines on the composition of DHCP or DHCPv6 messages,    designed to minimize disclosure of identifying information.
