摘要
One of the major security aspects in mobile communication networks concerns information about the localization of the (mobile) network user. This information may be protected by establishing a trusted third party that is responsible for creating suitable pseudonyms for the user identity. Distributing the maintenance of pseudonyms among n independent trusted parties allows to increase further the security of location information. In this paper, a method is proposed that guarantees security as long as at least one of the n parties may definitely be trusted whereas the other parties may turn out to be corrupt. The pseudonym collision probability is derived analytically before a detailed OPNET simulation evaluates the cost of the new approach compared to standard GSM.
