Motorcade-oriented safe mobility management method based on aggregation certification

Abstract

The invention belongs to the technical field of Internet of Vehicles, and discloses a motorcade-oriented safe mobility management method based on aggregation certification. An Internet of Vehicle-cellular network architecture which defines the network based on software is used, a vehicle enters into a road network and takes participate in the architecture, and then chooses to build a group; when amotorcade enters into the network, a new access point is detected by the vehicle, and the motorcade and a new access network perform mutual authentication; a group head accesses to the network, and the network returns back a response message; a motorcade member calculates a proxy signature thereof according to the response message; the group head collects signatures of all members in the same motorcade and aggregates into a new signature; then, the message and the new signature are sent to the network; the network verifies the new signature and authenticates all the member vehicles; and the member vehicles authentication the network. In combination with MIPv6-based mobility management, the method provided by the invention can realize safe and efficient motorcade-oriented mobility management, reduce authentication signaling overhead and switching delay and simultaneously guarantee data security of vehicle users.

Description

Technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, and in particular relates to a safety mobility management method for fleets based on aggregation authentication. Background technique [0002] At present, the existing technology commonly used in the industry is like this : In recent years, with the continuous growth of automobile usage, more and more problems have emerged, such as: the bearing capacity of roads has reached the limit in many cities, vehicle management and monitoring are difficult, traffic safety, travel efficiency, environmental protection, Safety communication of vehicles and other issues. With the widespread application of technologies such as the mobile Internet, the Internet of Things, and wireless sensor networks, the emergence of the Internet of Vehicles has largely solved the problems of traffic jams and traffic accidents. The Internet of Vehicles is one of the effective ways to achieve the goal of intelligent...

AI Technical Summary

Problems solved by technology

[0004] (1) There are long handover delays and lack of mobility support for roaming across various access networks

[0005] (2) There is a large computational overhead, and the authentication efficiency of the vehicle is low

[0006] (3) The group communication scenario in the vehicle network is not considered

[0007] The difficulty and significance of solving the above technical problems : In a heterogeneous network, access authentication is a key step to ensure secure communication, but most mobile IPv6 protocols only operate in the IP layer, and the authentication process is not considered during handover, but the authentication process is very important and will cause a large number of Delay; when a large number of vehicles want to access the Internet, they first need to access the wireless network safely, and should send access authentication requests to the core network in a short time or even at the same time, in addition, they must use IPsec to establish a connection with the core network These operations will result in communication and computing overhead for different nodes in the network on the communication path; if vehicles need to access the network almost simultaneously, each vehicle must perform a complete authentication and key agreement process with the core network separately, Then the traditional authentication protocol will suffer from high signaling overhead, which will lead to authentication signaling congestion and reduce authentication efficiency; due to the high communication and computing overhead, the original IPsec is not suitable for group-oriented vehicle environments; the significance of solving problem (1) lies in , can realize flexible and ubiquitous vehicle connection and real-time network management, ensure more efficient Internet access, ensure service continuity and quality of service (QoS) when the vehicle switches to another network, and provide services across various access Car roaming on the network provides transparent mobility support. The significance of solving problem (2) is that it can reduce the computational overhead of the scheme and improve the efficiency of vehicle authentication. The significance of solving problem (3) is that it can support high Mobility and a large number of vehicles, in the group situation, the group head can observe the movement status of the group members in real time for monitoring, in this group-based driving mode can collaboratively access various communication applications, such as data sharing or forwarding, And can significantly improve the performance of the vehicle network
