Half-Duplex Attack: An Effectual Attack Modelling in D2D Communication
This work addresses security vulnerabilities in next-generation wireless networks for users and operators, but it appears incremental as it builds on existing attack models by focusing on a specific phase.
The paper tackles the problem of security threats in Device-to-Device (D2D) communication within wireless networks by introducing a half-duplex attack that targets only the downlink phase, resulting in a reduced failed attempt rate compared to conventional full-duplex attacks, with analysis based on Poisson distribution to quantify this probability.
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 Poissons distribution to determine the probability of failed attempts of half duplex attack in contrast to a full duplex attack
