Vehicle information secure collection method applicable to fog computing in intelligent traffic light system

Abstract

The invention discloses a vehicle information secure collection method applicable to fog computing in an intelligent traffic light system. The method comprises a setting step, a registering step, a difficulty distribution step, a certificate generation step and an information collection step. The method is characterized in that locations and the number of vehicles cannot be counterfeited; a fog computing device does not need too much computing and storage cost; the identity and location information of the vehicles will not be leaked to other vehicles and fog computing devices; the method is easy to deploy; and the vehicle information statistics is accurate.

Description

technical field [0001] The invention relates to the fields of fog computing, intelligent transportation and information security, in particular to a vehicle information security collection method suitable for fog computing in an intelligent traffic light control system. Background technique [0002] Fog computing is a paravirtualized service computing architecture model between cloud computing and personal computing. Fog computing expands the network computing mode of cloud computing, and extends network computing from the network center to the edge of the network, so that it can be more widely used in various services. The intelligent transportation system effectively and comprehensively applies advanced information technology, data communication technology, sensor technology, electronic control technology and computer technology to the entire transportation management system, thereby establishing a large-scale, all-round functioning, real-time , accurate and efficient int...

AI Technical Summary

Problems solved by technology

Some scholars have proposed methods to detect the number of vehicles, but some of them are difficult to deploy, some have low accuracy, and some have high maintenance costs.

[0004] Some scholars have proposed to use the vehicle ad hoc network to collect traffic information for traffic lights, but the security issues have not been resolved, malicious vehicles may create false information so that they can quickly pass through the intersection, such as falsely claiming that there are many cars near the vehicle to obtain priority passing rights

Moreover, traffic lights need to communicate with the central control agency, which may cause a large delay. If the communication channel is interrupted, the entire system will not be able to operate.
