Smart Cities Smart Attacks
The types of security challenges in a smart transportation system can be divided into suspend message, fake information, denial of service, forgery of identity, eavesdropping, and hardware manipulation. Fake information occurs when information sent by an attacker, such as certificates, alerts, security messages, and IDs, is incorrect. The attacker alters, falsifies, or repeats data to mislead other drivers (Xie et al., 2020). Denial of service occurs when attackers send large volumes of irrelevant messages, clogging the communication channel and consuming computing resources of other nodes. The purpose of this attack type is to disable the case network of a vehicle that can have vital consequences in the event of an emergency (Yan et al., 2020). Also, forgery of identity occurs when an attacker pretends to be an authenticated vehicle or a roadside unit. Attackers use malicious IDs that have been hacked to inject malicious information into the network and mislead other vehicles. Eavesdropping also occurs when an attacker in a car or on a fake roadside unit eavesdrops on wireless communications in a car network (Geng et al., 2019). An attacker could gain access to the confidential data of the target vehicles, including the real identity of the drivers, their priorities or even their credit card information, and seriously infringe on the drivers privacy. Message suspension occurs as an attacker holds messages for a while before sending. An attacker electively holds messages packets from the system that may contain vital data for specific recipients (Saharan et al., 2020). One purpose of attack could be to forbid insurance authorities from being aware of the accident involving the attacking vehicle or to avoid reporting the accident to roadside access points. Eventually, hardware manipulation occurs when in-vehicle sensors or roadside unit hardware are tampered with by attackers. For example, an attacker could manipulate traffic lights in front of him that are always green (Chen et al., 2017).
