On the afternoon of May 17th, Professor Han Guangjie from Hohai University was invited to our college to give a special report titled "Multidimensional Dynamic Trust Management Mechanism in Acoustic Sensor Networks." The report was hosted by the dean of the college, Wang Meng, and more than 70 faculty and students attended the report.

In the report, Professor Han Guangjie focused on the theory and methods of network security in underwater acoustic sensor networks. He introduced the trust management mechanism in underwater acoustic sensor networks, including intrusion detection algorithms based on energy prediction models, multidimensional trust calculation methods based on fuzzy theory, trust evaluation algorithms based on cloud theory, trust cloud migration mechanisms based on AUVs, trust update mechanisms based on reinforcement learning, and anomaly-tolerant trust models based on isolation forests. At the end of the report, Professor Han interacted warmly with the teachers and students, and discussed issues related to network architecture, dynamic trust models, and multimodal heterogeneous networks.

This report discussed the key security theories and technologies in underwater acoustic sensor networks. The innovative methods and ideas presented in the report provided important inspiration and reference for the research work of our faculty and students.
