In the Applications, Platforms and Systems Security (APSS) research group we work toward enabling trustworthy systems and machine learning models. This requires addressing security, privacy and performance challenges across heterogeneous interconnected systems and application domains. We use measurements to improve our understanding of the issues which inform the design of novel methods for protecting user privacy and software integrity across mobile platforms, cyber-physical systems , and large-scale systems. Through collaborations we draw expertise across domains and work with industry to transfer knowledge to computing environments used by billions of users.
Below are some examples of our work:
- Authentication, Authorization and Access Control: Study of effective and efficient authentication, authorization and access control mechanisms.
- Mobile Device and IoT Systems Security: Study of adversarial capabilities and development of novel defense strategies for smartphone and IoT systems.
- Security and Privacy in Machine Learning and CPS: Study on the security and privacy of machine learning models and other applications in IoT and cyber-physical systems.
