Kennesaw State researcher wins grant to explore improved data security

KENNESAW, Ga. | September 25, 2024

The 2023 cybersecurity breach that compromised the data of 37 million T-Mobile customers highlights the need for better privacy solutions, as Xinyue Zhang of Kennesaw State University has been working on.

Zhang’s research focuses on the critical intersection of artificial intelligence (AI) and cybersecurity. His goal is to develop secure AI models that not only protect personal information but also reduce energy usage.

“AI is everywhere now. Smartphones, watches, computers, you name it. My research focuses on how we can protect our data privacy while using these technologies,” Zhang said. Her research is funded by a $173,754 grant from the National Science Foundation.

Zhang’s research focuses on federated learning, which enables AI models to run on multiple devices without sharing data, and NextG networks, a new generation of wireless technology that offers faster and more reliable connections. His goal is to create a federated learning system that overcomes certain vulnerabilities in current systems that leave data vulnerable to privacy breaches. The proposed system would improve data transmission security and limit AI training to individual phones, computers, and other devices to prevent cyberattacks.

Zhang’s academic journey began at Beijing Jiaotong University in Beijing, China, where he received his undergraduate degree. During his undergraduate studies, he participated in a double major program between Beijing Jiaotong University and KU Leuven in Belgium. After completing his undergraduate studies, he was accepted to the University of Houston for his doctoral studies.

Her doctoral studies at the University of Houston shaped her future focus. During her doctoral studies, she realized that AI was the future and decided to delve into AI research and a career in academia. Adjusting to life in Houston involved significant cultural changes, such as learning to drive and manage daily life independently. Despite these challenges, the experience was enriching and allowed her to build a network of friends and supportive colleagues.

Zhang’s decision to join KSU’s faculty was driven by the university’s focus on undergraduate research and supportive academic environment. He integrates his research into advanced cryptography courses and is excited about future technology trends, particularly quantum computing, which could transform AI by reducing training times and energy costs, though such developments may be a decade away.

Zhang’s success at KSU was supported by colleagues and mentors, including Professor Yong Pei, Chair of Computer Science at KSU, and senior faculty members such as professors Dan Lo and Selena He, whose guidance was crucial in his career.

“Dr. Zhang’s groundbreaking research at the intersection of AI and cybersecurity not only addresses critical data privacy challenges, but also paves the way for more secure and energy-efficient technologies,” said Dr. Pei.

“His innovative approach to federated learning and NextG networks exemplifies the forward-thinking mindset we value at Kennesaw State University, and his commitment to advancing these areas is truly inspiring.”

In the future, Zhang plans to continue her research, gain tenure, and establish a center for artificial intelligence and privacy at KSU, reflecting her commitment to advancing technology and student success.
