On December 20, 2024, Professor Chen Yu from the School of Cybersecurity, Shandong University, was invited by the School of Computer Science and Information Engineering to deliver an academic lecture titled “Construction and Implementation of a Unified Framework for Privacy Set Operations.” The event was held in the 5th Conference Room on the first floor of the Feicui Science and Education Building A. The lecture was hosted by Vice Dean Wang Hui, with attendance from the school 's Party Secretary, Nian Yongqi, relevant faculty members, and students.

In the lecture, Professor Chen shared the latest research achievements of his team in the field of privacy set operations. Privacy set operations allow two parties to securely perform set operations, such as intersection, union, and related functions of intersections and unions. Professor Chen presented a framework that can generate various private set operation (PSO) protocols, which perform better or are on par with the most advanced protocols currently available. Throughout the session, Professor Chen actively interacted with the audience, generously sharing insights from his research and personal experiences, creating a lively and engaging discussion atmosphere.
