Embodiment Construction

[0073] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0074] Such as Figure 3-Figure 5 As shown, the security-type defense collusion attack system under the Internet of Vehicles, including the existing IOC attack, will cause two-dimensional damage to the performance of TMAM, and IOC attackers are more likely to destroy the fairness and availability of TMAM. IOC consumers can send ratings based on information from co-conspirators. After several rounds of attacks, IOC attackers can help each other to quickly gain a high reputation score, making it easier to operate TMAM. In existing techniques, attackers only play the role of providers, sometimes relying entirely on their own honest behavior to improve their own reputation scores.

[0075] IOC attacks may affect the sentiment of trusted vehicles as they may not boost their own reputation score with trusted information. If their credible information diffe...

Abstract

The invention discloses a system and a method for safely defending collusion attacks under the Internet of Vehicles. The system and the method improve the reputation score of the system in an internalcollusion mode and an external collusion mode to manipulate a TMAM. The IOC attack can be rapidly detected, and the safety of the Internet of Vehicles is improved. Through recursion, suspicious providers and proposed reputation fluctuation association rules are eliminated, and overload of the TMAM is avoided. An IOC attacker can be deprived to prompt its reputation scoring opportunity and ensuretrusted information in the Internet of Vehicles. The fairness and the availability of the TMAM are ensured under the condition that the TMAM is not interfered by an IOC attacker. The defect that in the prior art, a reputation system can be utilized by an IOC attacker to improve the reputation score of the attacker so as to manipulate the TMAM is effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Vehicles, and also relates to the field of defense technologies, in particular to a system and method for securely defending against collusion attacks under the Internet of Vehicles. Background technique [0002] According to the definition of the China Internet of Things School-Enterprise Alliance, the Internet of Vehicles (Internet of Vehicles) is a huge interactive network composed of information such as vehicle location, speed, and route. Through GPS, RFID, sensors, camera image processing and other devices, vehicles can complete the collection of their own environment and state information; through Internet technology, all vehicles can transmit and gather their own various information to the central processing unit; through computer technology, these Information from a large number of vehicles can be analyzed and processed to calculate optimal routes for different vehicles, re...
