DESCRIPTION:Dr. Valtteri Niemi (Nokia Research Center)\nLTE security\nDr V
 altteri Niemi\, Nokia Research Center\nTue Dec. 6\, 15:15\, BC229\n\nAbstr
 act:\n\nLTE is a new radio technology that could be seen as the next gener
 ation after GSM and 3G. 3rd Generation Partnership Project (3GPP) has fina
 lized specification work for the two first releases already and the third 
 release is to be frozen soon. First deployments and products are also emer
 ging. LTE is accompanied by a new network architecture\, called SAE in 3GP
 P\, which allows also other radio technologies (including technologies not
  specified by 3GPP) to be connected to the one and same core network.\n\nT
 his new setting requires many enhancements to 3G security features\, and c
 ompletely novel security techniques are also introduced with LTE. More spe
 cifically\, the new architecture is flat (compared to GSM or 3G network ar
 chitectures) which restricts the possibilities of placing security functio
 ns on the network side. As a consequence\, some important security functio
 ns\, e.g. encryption of user data\, are terminated in the LTE base station
  site. This kind of very distributed approach to security requires many en
 hancements to the 3G security model.\nThe new security features would be c
 overed in the talk\, with explanations of the background and the reasoning
  behind the design decisions. Also\, comparison to GSM and 3G security arc
 hitectures is given\, and altogether\, light is shed on the evolution of s
 ecurity that has happened together with the evolution of the radio and net
 work technologies.
