A New Scheme for the Location Information Protection in Mobile Communication Environments - Computer Network Security - page 441

the reachability manager, where the NP will forge the personal information and call
subject at the intermediate position from the external user. It disguises for a call
request from the external user and is to send the personal information of the caller to
the MS through the reachability manager.
5 Conclusions
In this paper we considered improvements of the TP method and proposed a new
scheme, protecting an illegal attempt from the malicious network provider to find out
location information. We also showed that the proposed scheme is secure against the
active attacks through seven cases. Moreover, our scheme is more efficient than the
previous schemes and is easily applicable in a current mobile network.
