In mobile scenarios, privacy is an aspect of growing importance. In order to avoid the creation of movement profiles, participating nodes change their identifying properties on a regular basis in order to hide their identities and stay anonymous. The drawback of this action is that nodes which previously had a connection have no means to recognise this fact. A complete re-authentication would be necessary – if possible at all. This paper discusses this new problem and proposes two possible solutions for re-identification of anonymous nodes, one based on symmetric encryption and one based on secure hashes.
