Abstract

We propose a new scheme, protecting information about the location of a user against attacks from inside the mobile communication, especially the network providers. There have already been some proposals about how to protect location information in mobile communication environments. Among them, Kesdogan et al.[2,3] proposed a new method, using so-called temporary pseudonyms and also described protection method against passive and an active attacks. However, the protection method against an active attack is not clear. Moreover, there is an additional load in that it should append a reachability manager[1,6] to the proposed system. In this paper, we introduce a new scheme improving the method of Kesdogan et al. and analyze its security and effectiveness.
