Research on Data Security for Vehicle-Infrastructure-Cloud Integration

The security of data throughout its entire life cycle has become the most urgent and fundamental security issue in the digital economy era. With the continuous expansion and deepening of vehicle-infrastructure-cloud integration (VICI), data among the vehicle, infrastructure, and cloud are interconnected, leading to a constant extension in the scope of automotive data. Focusing solely on vehicle-end data is no longer sufficient to meet the developmental needs of intelligent connected vehicles. Considering data security from the perspective of VICI holds significant importance for ensuring the safety of the entire life cycle of intelligent connected vehicle data. In this context, this paper focuses on data security for VICI, analyzes the scope and characteristics of the data, explores the key challenges, and elaborates on the application of data security technology for VICI. Building upon this, the paper proposes DSA-VICI and conducts an analysis of the development trends in data security for VICI.
