Practical and secure multifactor authentication protocol for autonomous vehicles in 5G

Abstract

Autonomous vehicles (AV) can not only improve traffic safety and congestion, but also have strategic significance for the development of the transportation industry. With the continuous updating of core technologies such as artificial intelligence, sensor detection, synchronous positioning, and high‐precision mapping, the development of AV has been promoted. When 5G network is combined with Internet of Vehicles, the problems of AV can be solved by taking advantage of 5G ultra‐large bandwidth, low latency and high reliability. However, when the user controls the vehicle remotely, a real‐time and reliable authentication process is needed, while minimizing the overhead of security protocols. Therefore, this article proposes a practical and secure multifactor user authentication protocol for AV in 5G network. By introducing non‐interactive zero‐knowledge proof technology and physical uncloning function, the protocol completes mutual authentication and key agreement without revealing any sensitive information. The article proves the security of the protocol through BAN logic and the simulation of Scyther. And it can resist malicious attacks and provide more security features. The informal security analysis shows that the protocol can meet the proposed security requirements. Finally, we evaluate the efficiency of the protocol, and the results show that the protocol can provide better performance.

Application of Improved VMD-LSTM Model in Sports Artificial Intelligence

“…Hidden nodes are shown in Figure 1 . In the whole model, the parameters of the input gate, output gate, and forget gate in each hidden node are learned during the training process [ 26 ]. The calculation formulas for the three gates are as follows: …”

[Retracted] Layout Optimization Method of Public Service Facilities in Residential Quarters considering Time Distance

“…The above formula takes into account the influence of motor vehicle traffic load, but the influence of nonmotor vehicle traffic load is also very important because the factors that affect the driving time are not only the traffic load of motor vehicles but also the influence of nonmotor vehicles [ 21 ]. The road resistance model of the road segment calculated by the time distance calculation is derived by correcting the influencing factors such as lane width and intersection, as shown in where L is the length of the road section, v is the lane design speed, η is the lane correction coefficient, ϕ is the nonmotor vehicle impact reduction coefficient, and c is the lane design capacity.…”

Reform and Practice of College Japanese Test Mode Using Big Data Analysis

“…ACA (ant colony algorithm) is a bionic optimization algorithm, which has many advantages and is used to solve the vehicle scheduling problem [12], the color filling problem of connected graph, the salesman problem, and so on. However, ACA has some shortcomings, which will affect the solution of these problems.…”
