Spectrum sensing data tampering attack method, and distributed cognitive vehicle-mounted network

Abstract

The invention belongs to the technical field of vehicle-mounted communication, and discloses a spectrum sensing data tampering attack method, and a distributed cognitive vehicle-mounted network. The method comprises the following steps: an attacker monitors a common control channel, the attacker determines an initial moving speed, the attacker performs cooperative spectrum perception, and the attacker adjusts an own movement speed. According to the spectrum sensing data tampering attack method, according to the distribution condition of neighbor nodes of the attacker, the change rates of the neighbor nodes of the attacker and the current movement speed of the attacker, the movement speed of the attacker is dynamically adjusted to realize the quick change of the neighbor nodes, when the attacker detection difficulty is increased, the proliferation of erroneous sensing data across the entire network is accelerated, so that the spectrum sensing data are tampered more effectively, and theattack is more flexible.

Description

technical field [0001] The invention belongs to the technical field of vehicle communication, and in particular relates to a spectrum sensing data tampering attack method and a distributed cognitive vehicle network. Background technique [0002] Intelligent transportation and driverless technology require communication between vehicles to determine the smoothness of the road, provide road safety information in a timely manner, avoid potential safety hazards, and provide passengers with some entertainment services. Therefore, vehicular ad hoc networks play a fundamental but decisive role in areas such as intelligent transportation and driverless cars. With the increase of vehicle wireless communication services and applications, the demand for bandwidth will continue to increase, the problem of spectrum resource shortage is becoming more and more serious, and the channel congestion problem of vehicle network is becoming more and more serious. Due to channel congestion, vehic...

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the change of neighbor nodes in the process of spectrum sensing in the dynamic environment is not fully considered, and the movement of the attacker in the process of spectrum sensing in the dynamic distributed cognitive vehicular network makes the detection of the attacker difficult. The difficulty increases, and the attacker's false perception data will spread rapidly throughout the network, making the attack more efficient
