报告题目：Mobile Edge Caching and Its Security and Privacy Concerns
报告人：Jianbing Ni 教授
The proliferation of smart mobile and IoT devices has led to unprecedented amount of data generated at the edge. This trend has generated strong interests in pushing storage and computing capabilities to network edges, to fully unleash the potential of edge big data. By exploiting the storage and computing resources at the network edge, popular data can be temporarily maintained on cache-enabled edge nodes (e.g., macro base stations, Wi-Fi access points, and roadside infrastructure) for handling frequent data access requests from mobile users. Since the cached contents are delivered directly from edge nodes instead of from the remote cloud, it significantly reduces service latency, decreases network load, and improves user experience. Despite the appealing benefits of edge caching, it is vulnerable to a variety of cyber attacks, which results in huge concerns of security and privacy. In this talk, we give a brief introduction about edge caching and its security and privacy concerns. We first review the motivation for content caching running at the network edge. Then, an overview of the architecture, including content placement and content delivery, and related key enabling technologies for edge caching are provided. After that, we discuss the research challenges of the security and privacy in content placement and content delivery. Finally, we propose a secure byzantine-robust federated learning architecture for content placement and a service-oriented and location-based efficient key distribution protocol for content delivery as examples in response to secure and privacy-preserving mobile edge caching.
