On the afternoon of November 5th, the School of Engineering and Technology held the 67th lecture of the Yang-En Grand Lecture Series in the Boya Lecture Hall of the Hechang Teaching Building in the Third Teaching Area. Professor Wang Jilin, a PhD in Cryptography and supervisor of master's degree students, was the keynote speaker and students majoring in Big Data and Network Engineering attended the lecture.


During the lecture titled Random Numbers and Their Applications in Network Security, Professor Wang Jilin began by introducing the basic concepts of random numbers. He then used common real-life examples, such as coin tosses, WiFi authentication, and big data sampling, to vividly illustrate the core role of random numbers in cybersecurity. Through case studies, he pointed out that flaws in the random number generation mechanism could lead to the breach of encryption systems, resulting in serious information leaks.
Professor Wang Jilin compared and explained the current mainstream random number generation algorithms and their advantages and disadvantages, and offered a forward-looking perspective on the future development trends of random number technology. He systematically explained the three main characteristics of random numbers—randomness, unpredictability, and non-reproducibility—and emphasized that strongly random random numbers must be used in cryptographic and security systems to avoid potential security risks.
This lecture combined theoretical depth with practical application, providing students with a valuable learning and exchange opportunity, effectively broadening their professional horizons, providing a clear direction for their subsequent studies and research, and contributing to the cultivation of talent in the fields of cybersecurity and big data at our university.
