Query: An optimal security management framework for backhaul-aware 5G-Vehicle
  to Everything (V2X)   Cellular (C) setups facilitate the connectivity amongst the devices with
better provisioning of services to its users. Vehicular networks are one of the
representative setups that aim at expanding their functionalities by using the
available cellular systems like Long Term Evolution (LTE)-based Evolved
Universal Terrestrial Radio Access Network (E-UTRAN) as well as the upcoming
Fifth Generation (5G)-based functional architecture. The vehicular networks
include Vehicle to Vehicle (V2V), Vehicle to Infrastructure (V2I), Vehicle to
Pedestrian (V2P) and Vehicle to Network (V2N), all of which are referred to as
Vehicle to Everything (V2X). 5G has dominated the vehicular network and most of
the upcoming research is motivated towards the fully functional utilization of
5G-V2X. Despite that, credential management and edge-initiated security are yet
to be resolved under 5G-V2X. To further understand the issue, this paper
presents security management as a principle of sustainability and
key-management. The performance tradeoff is evaluated with the key-updates
required to maintain a secure connection between the vehicles and the
5G-terminals. The proposed approach aims at the utilization of high-speed
mmWave-based backhaul for enhancing the security operations between the core
and the sub-divided functions at the edge of the network through a dual
security management framework. The evaluations are conducted using numerical
simulations, which help to understand the impact on the sustainability of
connections as well as identification of the fail-safe points for secure and
fast operations. Furthermore, the evaluations help to follow the multiple
tradeoffs of security and performance based on the metrics like mandatory key
updates, the range of operations and the probability of connectivity.
