Security of trust infrastructure based on engineering and economics

Traditionally, information security research has been focused on confidentiality, integrity, and availability (CIA). However, to enhance digital transformations, we need to manage not only CIA relationships but also application-specific trust. As a core technology related to this topic, we study blockchain and cryptography as well as mechanism design and operational issues based on economics.
