A paper got accepted!

We are thrilled to announce that our paper has been accepted for presentation at the 9th IEEE European Symposium on Security and Privacy (Euro S&P 2024). Congratulations to Oyama-kun and the team!

H. Oyama, R. Iijima, T. Mori, “DeGhost: Unmasking Phantom Intrusions in Autonomous Recognition Systems,” Proceedings of Euro S&P 2024 (accepted for publication), pp. xxxx-xxxx, July 2024

This study addresses the vulnerability of autonomous systems to phantom attacks, where adversaries project deceptive illusions that are mistaken for real objects. Initial research assessed attack success rates from various distances and angles. Experiments used two setups: a black-box with DJI Mavic Air, and a white-box with Tello drone equipped with YOLOv3. To counteract these threats, the DeGhost deep learning framework was developed to distinguish between real objects and illusions, testing it across multiple surfaces and against top object detection models. DeGhost demonstrated excellent performance, achieving an AUC of 0.998, with low false negative and positive rates, and was further enhanced by an advanced Fourier technique. This study substantiates the risk of phantom attacks and presents DeGhost as an effective security measure for autonomous systems.

Welcome on board!

We’re excited to announce the arrival of four new PhD students in our lab, bringing our total number of PhD students to an impressive ten! Three of these new PhD students are pursuing their studies through a unique professional doctoral program, where they continue their work at their respective companies while advancing their research with us. This blend of academic and professional experience enriches the diversity and depth of knowledge in our lab.

Our master’s students also continues to grow, with thirteen students currently pursuing various advanced studies. In addition, we are pleased to welcome eight new undergraduate students. These students are the future of our research efforts, and their energy and fresh perspectives are invaluable to our team.

The range of research topics in our lab is as diverse as it is fascinating. Our work ranges from AI security and autonomous vehicle security to Web3 security, human factor security, physical space authentication techniques, and cybersecurity. This breadth of study reflects our commitment to pushing the boundaries of what’s possible and addressing some of the most pressing challenges in technology and society today.

We’re excited to see the contributions these new and continuing students will make to their respective fields. Their hard work and dedication make our lab a vibrant and innovative place. Welcome aboard, everyone! Let’s make great strides in research together!

A paper got accepted!

We are pleaased to announce that our paper has been accepted for publication at the Journal of Information Processing Information Processing Society of Japan (IPSJ). Congraturations, Watanabe-kun and the team!

T. Watanabe, E. Shioji, M. Akiyama, T. Mori, “Understanding the Breakdown of Same-Origin Policies in Web Services That Rehost Websites,” Journal of Information Processing, vol. xx, no. xx., pp. xxxx-xxxxx (in press)

This paper extends our original work presented at NDSS 2020 by providing detailed insights into the countermeasures implemented by global service providers, including Google, in response to our recommendations. These enhancements are crucial for understanding the evolving landscape of web service security. We elaborate on the real-world impact of our research in collaboration with JPCERT/CC.

Presented five posters at NDSS 2024

This year at NDSS 2024 held in San Diego, our team had the privilege of presenting five poster presentations, all focusing on the autonomous vehicle security. Some of these works were also showcased at VehicleSec 2024, reflecting our ongoing research projects under the JST CREST. The feedback we received from attendees was invaluable. Engaging with the community allowed us to gain new insights and perspectives, which are essential for refining our research and approaches.

Additionally, we organized a Mini NDSS Japan Night, an event that gathered around 20 researchers/students from the field. This intimate gathering proved to be a productive time for all, fostering discussions and collaborations that could shape the future of security research in Japan. These experiences underscore the importance of community and dialogue in the security research community. We are grateful for the engaging conversations and look forward to contributing further to this vital field.
