题目： Cyber Security Research in the University of Aizu: Security Framework for Internet of Everything
报告简介：We mainly focus on solving some identity authentication issues remaining in the IoT related application. Combined with blockchain, cryptographic protocols, dynamic Join-and-Exit mechanism and batch verification, a reliable and efficient security mechanism is proposed for smart IoT services. We also present our recent research results on machine learning applications in IoT security which is a crucial aspect for the cloud-based service in an IoT-enable environment. We will introduce our novel federated learning system which can both reduce the communication time by layer-based parameter selection and enhance the privacy protection by applying local differential privacy mechanism on the selected parameters.
