【摘要】 边端融合计算能够大大提升物联网场景下大数据的处理效率，为用户提供更快的响应，但其安全性是制约物联网发展应用的瓶颈。在分析边端融合系统面临的安全风险和安全需求基础上，针对边端融合系统“攻击面广、资源异构、计算和存储受限、环境复杂”等特点，重点对安全要素进行层次化细分，构建了一套通用的、可解释的边端融合系统安全评估指标体系，并提出了基于云重心理论的安全评估方法，为边端融合系统安全评估提供了一种有效的解决思路。更多还原

【Abstract】 Edge-end fusion computing can greatly improve the processing efficiency of big data in IoT scenarios and provide users with faster responses, but its security is a bottleneck in the development and application of IoT. Based on the analysis of the security risks and security requirements faced by the edgeend fusion system, in view of the characteristics of the edge-end fusion system such as wide attack surface,heterogeneous resources, limited computing and storage, and complex environment, this paper focuses on the hierarchical analysis of security elements, constructs a set of universal and interpretable edge-end fusion system security evaluation index system, and proposes a security evaluation method based on cloud center of gravity theory, which can provide an effective solution for the security evaluation of the edge-end fusion system.更多还原
