Fog-based road condition detection and authentication system and method

Abstract

The invention discloses a fog-based road condition detection and authentication system and a fog-based road condition detection and authentication method. The system comprises a vehicle, a roadside unit and a service center. The method comprises the following steps: the service center initializes the road condition detection and authentication system and generates system public parameters; the service center generates a private key and a public key respectively corresponding to the vehicle unit and the roadside unit; the vehicle unit signcrypts the real-time data and sends the generated signcryption ciphertext to the roadside unit; the roadside unit aggregates the received signcryption ciphertext to generate an aggregated signcryption ciphertext; the roadside unit verifies the correctnessof the aggregated signcryption ciphertext; and the roadside unit unsigncrypts the correct signcryption ciphertext. A fog framework supporting mobility, low delay and location awareness is used, improvement is performed on the basis of an existing certificateless aggregation signcryption method, a road condition monitoring authentication method is provided, a lot of time-consuming operation is reduced, and the safety of a vehicle unit and the efficiency of message authentication are improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an efficient and safe road condition detection and authentication system and method based on fog. Background technique [0002] With the development and progress of society, the total number of vehicles is increasing year by year, and the burden of urban traffic management is getting heavier and heavier. The continuous emergence of traffic jams and traffic accidents on the roads of vehicles has brought great challenges to the management of the traffic system. And, winter weather is always accompanied by snow, ice, and rain, all of which create potentially dangerous situations for people, vehicles, and property in harsh road conditions. By keeping abreast of the road conditions in each area, adjust the vehicle flow at each intersection to ensure smooth traffic. In addition, it can monitor the violations of road vehicles, discover and deal with road traffic accidents...
