Reputation Based Traffic Event Validation and Vehicle Authentication using Blockchain Technology

Blockchain Applications to Improve Operation and Security of Transportation Systems: A Survey

“…In the past, blockchain technology has been applied with great success in security and it has been shown to be an effective means of facilitating the spread of information between several connected systems. Because of these traits, a study that was conducted by authors of [12] attempted to integrate blockchain technology with existing CAV traffic event validation systems to quickly and effectively secure vehicle information and eliminate misleading information exchanged by malicious vehicles [12]. To test the proposed system, the team tracked the number of attackers and the ability of the blockchain-based system to detect when users were generating malicious information, with the blockchain technology using a reputation-based system to track the trustworthiness of certain users based on their past actions [12].…”

Its success heightens an area of particular importance for the use of blockchain technology in CAVs: attack mitigation and user safety.…”

“…Attackers are known for using any means possible to compromise user data, overwhelm networks, and potentially cause dangerous situations for users. In the case of AVs, any form of lax security and safety measures can prove to be fatal due to the inherent hazards that are involved in driving and managing past and present location-sensitive information of users [12,13].…”

“…As of now, the blockchain solution has already been incorporated across varying areas of study with great success, which has led many to wonder whether it can be applied similarly to other emerging fields [8]. Among these fields, the applications of blockchain in CAVs have been extensively studied [12][13][14]. Through these studies, a wide spectrum of methods have been proposed on how blockchain can be incorporated to add and expand on existing CAV functionality, coupled with a number of tests indicating the feasibility of implementations [17,18].…”
