PUF-based lightweight IOV (Internet of Vehicles) system security authentication method

Abstract

The invention relates to a PUF-based lightweight IOV (Internet of Vehicles) system security authentication method, and belongs to the field of computer information security. The method comprises the following steps: (1), first analyzing the communication process in the two scenarios of a vehicle-mounted mobile Internet and an inter-vehicle network: the first scenario is communication between a vehicle and the Internet, and the second scenario is communication between the vehicles; (2), performing the security analysis of the protocols in the two scenarios, starting from the authentication encryption algorithm and protocol authentication process adopted in the protocols, and analyzing whether the two protocols can resist various security threats or not; (3), starting from the authenticationencryption algorithm in the protocol and the interaction process of a subject involved in the protocols, and analyzing the calculation amount of the protocols, storage requirements and communicationrequirements. The method can protect the interactive data from being easily stolen, and protect the interaction process from being easily attacked.

Description

technical field [0001] The invention relates to a PUF-based lightweight vehicle networking system security authentication method, which belongs to the field of computer information security. Background technique [0002] With the development and application of the Internet, the Internet of Vehicles, as a derivative of the Internet, has gradually become the focus and hotspot of current research. The information security of the Internet of Vehicles has also become one of the bottlenecks restricting its development. Attackers exploited security vulnerabilities in Tesla's automotive systems to successfully complete remote attacks without physical contact, and realized remote control of car lights, display screens, door and window locks, and other operations; BMW's "Connected Drive ( Connected Driving System)" digital service system has been compromised, attackers can remotely open the car door; Tesla Model S (a full-size high-performance car model manufactured by Tesla) intrusi...

AI Technical Summary

Problems solved by technology

[0004] Many experts and scholars in the industry have carried out a lot of research and proposed a variety of protocol authentication schemes for the Internet of Vehicles, but these protocols have certain defects or deficiencies, and it is difficult to resist bad attacks. , practical, and applicable to low-cost solutions to vehicle system safety problems
