Problems solved by technology

[0009] Second, the reasonable coordination of the two contradictions of safety and efficiency is also a big challenge
But it will bring a lot of network overhead and reduce the communication efficiency
Nevertheless, security is an issue that must not be ignored, because an unsecured network is more dangerous than an overloaded and congested network

Embodiment Construction

[0041] like figure 1 The shown RSU-based VANET security information aggregation transmission system includes four parts: authentication center, vehicle unit, roadside unit and IEEE802.11q communication circle; among them,

[0042] Transportation Authority (TA for short): It is a trusted security center responsible for the identity authentication of each node in VANET, issuing certificates, maintaining revocation lists, and saving management node information. This organization can be compared to the CA in the PKI system, which is managed by the relevant national or regional transportation authorities according to the actual area of ​​VANET. Generally speaking, the center was established earlier than VANET, and needs to carry out the highest level of security guarantee (perfect security system and security strategy), and maintain online and secure connection with the RSU in its jurisdiction (or authorize other management entities to act on behalf of this function), and is respon...

Abstract

The invention discloses a method for transmitting a VANET (vehicle ad hoc network) safety information aggregate based on RSU (Remote Subscriber Unit). The RSU serves as a communication group leader, messages of legal vehicles in a governed region are subjected to information aggregating processing by an aggregate signature algorithm and are further transmitted to a monitoring center, the monitoring center verifies the correctness of signature information at one time through an inverse aggregate signature algorithm, and meanwhile when a false message is found, the real sender of the message can be accurately positioned by starting a tracing process under the assistance of an authentication center. The method has the advantages that double requirements on safety and efficiency of vehicle ad hoc network information transmission are effectively met, and limited transmission wideband is effectively saved on the premise of not affecting the safety by performing aggregating processing on vehicle safety information in the road side unit governed region in a vehicle ad hoc network.

Description

technical field [0001] The invention belongs to the field of vehicle ad hoc network information security protection, and relates to a safety information aggregation protocol in a vehicle ad hoc network. Background technique [0002] Vehicle AdHoc Network (VANET for short) is a dedicated ad hoc network for inter-vehicle communication. important manifestation. VANET is not only flexible in networking, it can be networked independently by vehicles close to the geographical location, and can also be connected to other fixed or mobile networks through roadside units, and can provide rich services, such as content distribution, news and entertainment, in-vehicle Office, instant messaging, etc. make the transportation network more safe, efficient, comfortable, "low-carbon" and "green", and can also have a huge impact on economic and social development. In recent years, it has become an important research hotspot and industrial hotspot . [0003] With the large-scale and high-fre...
