Dr. Keke ChenMilwaukee — Dr. Keke Chen, associate professor of computer science at the Northwestern Mutual Data Science Institute at Marquette University Klingler College of Arts and Sciences, has received a $600,000 grant from the National Science Foundation to research confidential computing solutions in scientific collaboration. received the money.

Chen’s research project, “Sensitive Computing in Reproducible Collaborative Workflows,” was licensed through the NSF’s Cybersecurity Innovations for Cyberinfrastructure program. NSF CICI supports research to protect scientific data, workflows and infrastructure in three areas of focus. Browse scientific security datasets. Discovery of vulnerabilities in scientific infrastructure.

“Data-intensive scientific research projects often involve multiple collaborators. We may require the classified processing of sensitive assets to ban “Integrating confidential computing into reproducible scientific workflows raises significant challenges that have not yet been fully explored. purpose.”

This research focuses on an efficient hardware-based confidential computing approach, a Trusted Execution Environment (TEE) for scientific data analysis applications. Researchers consider TEE development solutions for scientists, considering the trade-offs between ease of use and security assurance. We also study unique attacks derived from interactions between sensitive components and reproducible workflows, and develop mitigation methods based on attack research to ensure reproducibility and security of workflows.

Dr. Heidi Bostic, Dean of the Klingler College of Arts and Sciences, said: “Dr. Chen and his research team seek to remove confidentiality and privacy concerns that can hinder open collaboration and collaborative science. It can be extended to other confidential computing scenarios on potentially untrusted platforms.His work is a great example of Marquette’s outstanding strengths in computer and data science.”

Chen’s team includes collaborators Zeno Franco, Ph.D., assistant professor of family and community medicine at the Medical College of Wisconsin, and Ze Yun Yu, Ph.D., professor of computer science and biomedical engineering at the University of Wisconsin-Milwaukee. increase. Her Dr. Ning Jenny Jiang, Associate Professor of Innovation at the University of Pennsylvania, J. Peter and Associate Professor Geri Skirkanich serve as independent consultants.

By enhancing the curriculum of cybersecurity programs at Marquette, a broader impact will be felt across the field. Create new course materials for Marquette’s Data Science program and UWM’s Bioinformatics program. Contribution to computer science education in local high schools. Attracting underrepresented undergraduates to cybersecurity and data science research through Marquette’s programs. Strengthen university cooperation with industrial partners.
