5G device-to-device communication security and multipath routing solutions

Abstract

Through direct communication, device-to-device (D2D) technology can increase the overall throughput, enhance the coverage, and reduce the power consumption of cellular communications. Security will be of paramount importance in 5G, because 5G devices will directly affect our safety, such as by steering self-driving vehicles and controlling health care applications. 5G will be supporting millions of existing devices without adequate built-in security, as well as new devices whose extreme computing power will make them attractive targets for hackers. This paper presents a survey of the literature on security problems relating to D2D communications in mobile 5G networks. Issues include eavesdropping, jamming, primary user emulation attack, and injecting attack. Because multipath routing emerges as a strategy that can help combat many security problems, particularly eavesdropping, the paper contains an extensive discussion of the security implications of multipath routing. Finally, the paper describes results of a simulation that tests three path selection techniques inspired by the literature. The simulation reveals that routing information through interference disjoint paths most effectively inhibits eavesdropping.

Investigating the Technological and Political Challenges of V2V Communication in Light of an Experimental Scenario Set Up

“…Thirdly, more realistic experiments including VANET solutions utilizing different communications technologies should also be of high priority. These are all examples of contexts that are highly interesting for investigating the ability of ITS-G5 to be a successful communication technology alone or together with other technologies such as 5G solutions, and in particular the device-to-device communication functionality included in this emerging technology [50]. While communication in transport has been characterized by competing technologies, we argue that the larger benefit would only be realized when the technologies are not seen as competitors, but as supplements.…”

“…In addition to that their system requires N L o real multiplications and K f N L o additions where the complexity due to FFT operation is not included. 1 Please see appendix for derivation…”

“…Each of these risks impacts the performance and reliability of the communication link. For example, in eavesdropping, an intruder can listen to the exchange of information in a communication link, which could be severe security threat depending on the information and motives of the intruder [1]. The Anti-Jamming (AJ) induces an ability in the communication link to prevent itself from being blocked by tuning into the transmitter's frequency [2], [3].…”
