Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the above-mentioned accompanying drawings. It should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

[0045] like figure 1 As shown, VANET mainly includes three components: On-Board Unit (OBU), Roadside Unit (RSU) and Trusted Authentication Authority (TA). However, the security authentication protocol described in the present invention mainly refers to vehicle-to-vehicle communication (V2V), ie does not involve the RSU component. The security authentication scheme described in the present invention mainly involves two parts, TA and OBU. TA is responsible for the distribution and management of keys, and the tracking of malicious vehicles. OBU is responsible f...

Abstract

The invention provides an unmanned safety communication authentication protocol, which belongs to the field of information and communication of the self-organized network of unmanned motor vehicles. In this protocol, the vehicle obtains private data from the TA, generates a pseudonym and corresponding private key offline, and uses bilinear mapping to realize user authentication, thereby ensuring the security and privacy of the vehicle. The invention also uses the hash chain element as the key for generating the message authentication code, and adopts the method of delayed exposure. The receiver receives the delayed-obtained hash chain element and verifies whether the previous message authentication code can be generated. In addition, by generating a predicted value and sending it to the receiver, the present invention enables the receiver to verify the validity of the message in real time, thereby enhancing the robustness of the protocol. The invention has the effects of anonymity and privacy protection, and can ensure the verifiability and integrity of data. In addition, this protocol also has the characteristics of non-repudiation, non-correlation, conditional privacy protection, anti-replay, anti-packet loss, etc., which can ensure normal communication authentication.

Description

technical field [0001] The invention relates to a security communication authentication protocol for unmanned vehicles, aiming at information such as road conditions, driving conditions, emergency accidents and other information exchanged between unmanned vehicles, through security authentication, verifying the legality of the sender's identity, information integrity, etc., At the same time, it protects the privacy of the sender itself, and belongs to the field of unmanned motor vehicle ad hoc network information and communication. Background technique [0002] Vehicle Ad Hoc Networks (VANETs) is an implementation form of Mobile Ad Hoc Networks (MANETs). Because of the characteristics of autonomy and no fixed structure, multi-hop routing, dynamic changes in network topology, limited network capacity, and good scalability, VANET is widely used. The vehicle ad hoc network is mainly composed of three parts, namely the on-board unit (On-board Unit, OBU) installed on the vehicle...
