Is Future of Safety in Autonomous Vehicles Blockchain or IOTA?Speaker: Heena Rathore – Austin, TX, United States
Topic(s): Security and Privacy
Connected vehicles are set to define the future of transportation, however, this upcoming technology continues to be plagued with serious security risks. If these risks are not addressed in a timely fashion, they could threaten the adoption and success of this promising technology. This lecture covers a specific class of security threats in connected vehicles, namely information correctness threats (due to compromise of on-board sensors). Current centralized solutions that employ trusted infrastructure to protect against adversarial manipulation of information cannot validate the correctness of the shared data and do not scale well. In order to overcome this issue, decentralized protection mechanisms by means of blockchain technology have emerged as a promising research direction. However, current permission-less, linear hash-chain based blockchain solutions have low transaction performance, high computational cost, and are resource intensive, thereby making it difficult to adopt them for security in connected vehicles. An alternative has emerged in the form of IOTA, which is a distributed ledger technique specifically designed forresource and power sensitive devices, typically found in IoT applications. It uses a directed acyclic graph, called Tangle, which is light weight in its implementation and the amount of work that has to be done to be considered part of the network.
In this talk, we discuss how IOTA can beadapted for the use-case of connected vehicles. We discuss how IOTA can be integrated with the current Security Credential Management Systems to aid with the roles of pseudo certificate authorities and misbehavior detection authorities. The results will demonstrate the effectiveness of this technique and discuss how we can handle the scenario of cars moving in and out of the network.
At the end of the lecture, audience will be able to apply blockchain or IOTA based distributed ledger technqiues tomake connected vehicles more secure.
