Half-Duplex Attack: An Effectual Attack Modelling in D2D Communication

Abstract

The visualization of future generation Wireless Communication Network (WCN) redirects the presumption of onward innovations, the fulfillment of user demands in the form of high data rates, energy efficiency, low latency, and long-range services. To content these demands, various technologies such as massive MIMO (Multiple Input Multiple Output), UDN (Ultra Dense Network), spectrum sharing, D2D (Device to Device) communication were improvised in the next generation WCN. In comparison to previous technologies, these technologies exhibit flat architecture, the involvement of clouds in the network, centralized architecture incorporating small cells which creates vulnerable breaches initiating menaces to the security of the network. The half-duplex attack is another threat to the WCN, where the resource spoofing mechanism is attained in the downlink phase of D2D communication. Instead of triggering an attack on both uplink and downlink, solely downlink is targeted by the attacker. This scheme allows the reduced failed attempt rate of the attacker as compared to the conventional attacks. The analysis is determined on the basis of Poisson's distribution to determine the probability of failed attempts of half duplex attack in contrast to a full duplex attack.
