LTE security

Abstract:
LTE is a new radio technology that could be seen as the next generation after GSM and 3G. 3rd Generation Partnership Project (3GPP) has finalized specification work for the two first releases already and the third release is to be frozen soon. First deployments and products are also emerging. LTE is accompanied by a new network architecture, called SAE in 3GPP, which allows also other radio technologies (including technologies not specified by 3GPP) to be connected to the one and same core network.
This new setting requires many enhancements to 3G security features, and completely novel security techniques are also introduced with LTE. More specifically, the new architecture is flat (compared to GSM or 3G network architectures) which restricts the possibilities of placing security functions on the network side. As a consequence, some important security functions, e.g. encryption of user data, are terminated in the LTE base station site. This kind of very distributed approach to security requires many enhancements to the 3G security model.
The new security features would be covered in the talk, with explanations of the background and the reasoning behind the design decisions. Also, comparison to GSM and 3G security architectures is given, and altogether, light is shed on the evolution of security that has happened together with the evolution of the radio and network technologies.
