ABSTRACT: The number of security features has been growing steadily during the evolution of cellular communication systems. We go briefly through security solutions in 1st, 2nd and 3rd generation systems. The main part of the talk is about security aspects in the emerging LTE/SAE system of 3GPP. The LTE refers to a completely new radio system while SAE refers to a new core system into which many different radio technologies can be attached.

The talk would also give an overview of Nokia Research Center both in general level and, in particular, NRC security area activities.

BIO: Valtteri Niemi received the M.Sc degree from the University of Turku, Finland, Mathematics Department, in 1987 and the Ph.D. degree from the same department in 1989. He held several research and teaching positions at the University of Turku, including acting as an Associate Professor in Mathematics for the academic year 1992-3. In 1993, Niemi was nominated as an Associate Professor in the Mathematics and Statistics Department of the University of Vaasa, Finland, where he stayed until joining the Nokia Research Center, Mobile Networks laboratory, Helsinki in 1997. In 1999, he was nominated as a Research Fellow, and starting from 2004, he has been responsible for Nokia research in wireless security area.

Dr. Niemi now works on security issues in future mobile networks and terminals, the main emphasis being on cryptological aspects. He has participated 3GPP (3rd Generation Partnership Project) security standardization group from the beginning, and starting from 2003, he has been the chairman of the group.
