随着自动驾驶汽车使用的增加，交通基础设施作为一个整体变得更容易受到网络攻击，因为可以相互通信的组件和互联网的增加。已有研究表明，自动驾驶汽车不能通过合作来执行许多成本和生命节约的应用，例如追尾、高级碰撞警告，甚至是跨ffi路径选择。为了保护交通基础设施免受这种不断增加的风险，本文提出了一种适用于自动车辆的车载自组织网络的effi区块链方案。在提议的方案中，每辆车维护由其排生成的区块，其中包含评估每辆车行动的交易。因此，车辆将拥有不同的区块，从而在加入和离开平台时拥有不同的区块链(ffff)。不维护中央区块链。这些街区被车辆用作进入未来排的标志。该方案使用Schnorr数字签名方案来创建安全的签名，并在排内达成共识。在给定的假设条件下，证明了它是安全的。
As the use of autonomous vehicles increase, the transportation infrastructure as a whole becomes more susceptible to cyber-attacks due to the increase of components that can communicate with one another and the Internet. It has been shown that autonomous vehicles benefit greatly from cooperating to perform many cost and life-saving applications such as tailgating, advanced collision warning, and even traffic routing. To secure the transportation infrastructure against this increasing risk, this paper presents an efficient blockchain scheme for vehicular ad-hoc networks of autonomous vehicles. In the proposed scheme, every vehicle maintains blocks generated by its platoon which contain transactions that evaluate the actions of every vehicle. Thus, vehicles will possess different blocks and thus different blockchains as they join and leave pla-toons. No central blockchain is maintained. These blocks are used as a token by the vehicle to gain access to future platoons. The proposed scheme uses the Schnorr digital signature scheme to create a secure signature and reach consensus within the platoon. It is proven to be secure under the given assumptions.
