On the Security of the UMTS System
Stefan Pütz, Roland Schmitz, Tobías Martín · 2001
This contribution presents an overview of the security of the 3 rd generation mobile radio system UMTS as currently standardised by the 3 rd Generation Partnership Project 3GPP. We discuss the underlying principles and show to which extent the security of 2 nd generation systems as GSM is improved and enhanced by UMTS. The UMTS Authentication and Key Agreement protocol, the security algorithms deployed for UMTS and the interworking mechanisms between 2 nd and 3 rd generation systems are described in detail.
