Research on the regulatory framework and full-chain security protection scheme for OTA updates of intelligent connected vehicles
Year: 2025
Type: conference-paper
Abstract: With the acceleration of the intelligentization process of new energy vehicles, software updates based on OTA technology have emerged as a crucial paradigm in the full lifecycle management of vehicles. This study conducts a systematic analysis from two dimensions: regulatory compliance and cybersecurity. Firstly, by dissecting domestic and international standards such as UNECE R156 and GB "General Technical Requirements for Software Update of Vehicles" it proposes a compliance framework encompassing enterprise-level process control and vehicle-level technical implementation, with a focus on establishing two core mechanisms: software update development management processes and vehicle model development implementation. Secondly, the study analyzes the security risks associated with OTA updates across the "cloud-communication-vehicle" chain and proposes constructing a full-link security protection system through technologies such as cloud-based dynamic key management, full-chain encryption of communication channels, and a trusted root on the vehicle-side hardware. The research findings provide actionable technical pathways for compliant operations and security practices in OTA updates for intelligent connected vehicles.
