The NB-IoT and LTE-M technologies continue to evolve as a part of the 5G speci cations with upcoming releases of 3GPP. The assessment of security threats such as attacks on inter-operator security, radio interfaces, signaling and user plane, masquerading, replay, man-in-middle, bidding-down and privacy security is- sues have been considered for the 5G system. However, there is a scope for improvement in end-to-end security authentication for 5G NB-IoT. The user identity related issues are still a concern as the existing authentication protocols provide poor compatibility with current network architecture. In addition, these protocols demands dual authenti- cation and key agreements. In this paper, we are proposing an application of Whirlpool Hash Function and Physical Unclonable Function (PUF) for an end-to-end authentication method for NB-IoT devices over 5G network.50 pagesenBrac University theses are protected by copyright.
