A Fleet-Oriented Secure Mobility Management Method Based on Aggregated Authentication

Abstract

The invention belongs to the technical field of the Internet of Vehicles, and discloses a fleet-oriented security mobility management method based on aggregation authentication, adopting a software-defined network-based Internet of Vehicles-cellular network architecture, vehicles enter the road network and participate in the architecture, and then choose to establish Group; after the fleet enters the network, the vehicle detects a new access point, and the fleet and the new access network perform mutual authentication: the group leader accesses the network, and the network returns a response message; the fleet members calculate their proxy signatures based on the response message; the group The head collects the signatures of all members of the same team and aggregates them into a new signature; then sends the message and the new signature to the network; the network verifies the new signature and authenticates all member vehicles; the member vehicle authenticates the network. Combined with MIPv6-based mobility management, the present invention can realize safe and efficient fleet-oriented mobility management, reduce authentication signaling overhead and handover delay, and at the same time ensure data security of vehicle users.

Description

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

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
