Blockchain-Based Framework for Secure OTA Updates in Autonomous Vehicles
Authors:- Siranjeevi Srinivasa Raghavan
Abstract- – This paper presents a blockchain-based framework designed to enhance the security of Over-the-Air (OTA) updates in autonomous vehicles. By leveraging the decentralized, immutable, and transparent nature of blockchain technology, the framework ensures the authenticity and integrity of software updates. A smart contract-driven approval mechanism prevents unauthorized modifications while addressing critical challenges such as latency, scalability, and energy efficiency. The study evaluates the trade-offs in blockchain adoption for vehicular systems, offering a detailed analysis of its impact on operational performance. Results demonstrate that the proposed framework significantly improves OTA update security without compromising real-time requirements or resource constraints, making it a viable solution for secure vehicular ecosystems.
