Abstract

The papers in this special section focus on blockchain for vehicles and intelligent communications. The proliferation of vehicles and intelligent communications is generating enormous amount of data for enabling autonomous driving and innovative communications applications. The data may raise efficiency and security concerns to users, e.g., offering real-time services for smart phones/devices/vehicles and exposing sensitive driving information to the untrusted 3rd party. Blockchain, which is featured with decentralization recording and tamper-proofing, has been emerged as a promising approach for mitigating data security risks of vehicles and intelligent communications. In addition, incorporating with smart contracts and other techniques, users connected through blockchain can share the data information in an efficient, private and secure manner, thereby reducing the management cost of service provision, improving the security of intelligent communications, and protecting the privacy of vehicles and mobile users. Further, highly dynamic communication topology caused by driving vehicles may undermine the establishment of consensus protocols. Thus, efficiency will become a critical challenge in leveraging blockchain for delay sensitive services in vehicular and intelligent communications.
