【Abstract】Connected Autonomous Vehicles (CAVs) are becoming data centers on wheels, amassing petabytes of data. They require a combination of software and hardware systems to operate reliably and simply in realtime. However, due to the transient nature of Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) networks and CAVs' dependency on a connected software system, we need a new paradigm for secure and immutable data exchange, which emulates smart contracts. For this reason, CAV manufacturers need to maintain the latest version of software to protect CAVs from system failure and cyber threats in real-time, which is difficult with traditional centralized management. The key challenges that we must overcome are the authentication and secure sharing of the Over-The-Air (OTA) software updates and the scalability of distribution at the level of CAVs.This paper proposes a secure and scalable software updates framework in a distributed manner for the CAVs, leveraging Blockchain (BC) with smart contract technology. The framework is able to overcome slow processing speed, which is one of the significant limitations of BC in terms of lower latency and less packet overhead with a high level of security against possible cyber-attacks. We use a salting based hashing scheme over the traditional Elliptic Curve Cryptography (ECC) Key. This process ensures multi-factor authenticated protection from malicious transactions while downloading and installing any new feature update in CAVs. Moreover, by using Hyperledger BC, our framework provides cost-free transactions while successfully upgrading and deploying OTA software patches in any system of CAVs. This paper extends our previous work [51] by analysing our proposed BC framework's immutability and load management capability. Our simulation results show that our proposed framework is robust, secure, and failsafe for CAV manufacturers and end-users.& COPY; 2023 Elsevier Inc. All rights reserved.
