However, when both parties are successfully authenticated, in some specific application scenarios, the vehicle needs to present relevant identity information to obtain certain application services, and if it relies on group signatures, the vehicle only informs the other party of the identity of the group owner rather than its own Identity information, which makes it difficult for vehicles to obtain relevant application services in an effective way

Embodiment Construction
[0075] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0076] The purpose of the present invention is to provide an anonymous communication system and method based on ring signature in the vehicle network, which integrates pseudonym certificate and group signature technology, and can fully protect the privacy of communicators under the premise of ensuring authentication efficiency.
[0077] The invention applies the anonymous authentication system and method based on the ring signature to the access authentication link of the vehicle network, and fully protects the security and efficiency of the authentication process while realizing the user access authentication. Such as figure 1 As shown, it is a schematic framework diagram of the ring signature-based vehicle network anonymous communication system of the present invention. exist figure 1 Among them, TA (TrustedAuthority) represents the third-p...

The invention relates to the technical field of network security, and provides a ring signature-based vehicle network anonymous communication system, including a third-party trust organization, a roadside unit and a vehicle. The present invention also provides a method for using the above-mentioned system to carry out anonymous communication on the vehicle network. The third-party trust agency first publishes public parameters, and then the vehicle and the roadside unit apply for registration to the third-party trust agency, and the third-party trust issues a pseudonym, public and private keys for the vehicle , to issue public and private keys and initial pseudonym ring members for the roadside unit, and then monitor the status of the vehicle in the vehicle network: if the vehicle is connected to the vehicle network for the first time, it will perform initial access authentication with the roadside unit RSU; if the vehicle is not When accessing the vehicular network for the first time, the handover access authentication is performed with the roadside unit RSU'; if the vehicle Vi and the vehicle Vj are ready to communicate, two-way authentication is performed with the assistance of the roadside unit. The invention integrates the pseudonym certificate and the group signature technology, and can fully protect the privacy and safety of the communicator under the premise of ensuring the authentication efficiency.
Description
technical field [0001] The invention relates to the technical field of network security, in particular to an anonymous communication system and method for a vehicle network based on a ring signature. Background technique [0002] Today, with the rapid development of the transportation industry and the communication industry, people's demand for traffic congestion information query, safe driving and various entertainment provided by the network is increasing during driving. The in-vehicle network, as a network that mainly provides communication for vehicles at present, can dynamically transform the network topology structure during the fast driving process of the vehicle, and provide continuous and stable communication services. However, in order to ensure the timely accessibility of communication messages, all messages sent by vehicles are sent in the form of broadcast, and any communication device around the vehicle can receive the messages sent by the vehicle, which makes ...
