DESCRIPTION:Cellular devices support various technical features and servic
 es for 2G\, 3G\, 4G and upcoming 5G networks. For example\, these technica
 l features contain physical layer throughput categories\, radio protocol i
 nformation\, security algorithm\, carrier aggregation bands and type of se
 rvices such as GSM-R\, Voice over LTE etc. These technical features and ne
 twork services termed as 'device capabilities' and exchanged with the netw
 ork during the device registration and Authentication and Key Agreement (A
 KA) protocols. The 3rd Generation Partnership Project (3GPP) responsible f
 or the worldwide standardization of cellular communication networks has de
 signed and mandated the use of the AKA protocol to protect the subscribers
 ’ mobile services. \n\nIn this talk\, we discuss several vulnerabilities
  discovered in cellular device authentication and registration process in 
 5G networks. Low-cost hardware setup\, proof-of-concepts attacks to demons
 trate the impact\, countermeasures\, and remedial actions from 3GPP/GSMA f
 or 5G networks will also be presented.
