LIST is a mission-driven Research and Technology Organisation (RTO) that develops advanced technologies and delivers innovative products and services to industry and society. The Trustworthy Data Systems (TRUST) research group at LIST is contributing to the establishment of trustworthy data systems, with a special focus on safeguarding critical infrastructures (e.g., 5G) vital to security. This is achieved by harnessing the cutting-edge arsenal of technologies including adversarial attacks and defenses, privacy-enhancing technologies, and homomorphic encryption schemes. These initiatives collectively bolster our mission to ensure that data systems underpinning AI technologies are fortified against adversarial threats, thereby instilling a sense of unwavering confidence in the integrity and security of AI-driven applications.
