| 초록 |
In the evolving landscape of software-defined vehicles(SDVs), the demand for a robust and secure firmware update mechanism has grown substantially. Traditional verification methods that rely on vendor signatures, metadata, and timestamps are limited in guaranteeing absolute integrity. Despite the rising traction of decentralization in blockchain technology, its validation within automotive over-the-air(OTA) update scenarios remains inadequate. Moreover, within the automotive OTA domain, reliability takes precedence, though the pivotal role of performance must also be emphasized. Therefore, this research attempted to address these challenges by introducing an innovative strategy to enhance the integrity and reliability of over-the-air firmware updates(FOTA). The strategy can harmoniously integrate the widely acknowledged Message Queuing Telemetry Transfer(MQTT) protocol, a cornerstone in IoT applications, with blockchain-based verification methods, particularly focusing on Merkle trees. Its primary objective is to elevate both the dependability and efficiency of SDV firmware updates. |
