Abstract: With the advent of 5th generation (5G) technology, the mobile paradigm witnesses a tremendous evolution involving the development of a plethora of new applications and services. This enormous technological growth is accompanied with an huge signaling overhead among 5G network elements, especially with emergence of massive devices connectivity. This heavy signaling load will certainly be associated with an important security threats landscape, including denial of service (DoS) attacks against the 5G control plane. In this paper, we analyse the performance of a defense mechanism based randomization technique designed to mitigate the impact of DoS signaling attack in 5G system. Based on massive machine-type communications (mMTC) traffic pattern, the simulation results show that the proposed randomization mechanism decreases significantly the signaling data volume raised from the new 5G Radio Resource Control (RRC) model under normal and malicious operating conditions, which up to 70% while avoiding the unnecessary resource consumption.

Keywords: 5G New Radio (NR) network; Radio Resource Control (RRC) state model; Denial of Service (DoS); signaling threats; randomization
