| Abstract for Research Report | Card-based cryptography is a subfield of cryptography that realizes cryptographic tasks such as secure computation and zero-knowledge proof using a deck of physical cards. Its feature is that protocols can be executed visually and experientially by human hands. Early research on card-based cryptography was developed in the 1990s, but in the 2010s, the research group led by the applicant proposed a mathematical model of card-based protocols via abstract machine. In recent years, the number of papers on card-based protocols has been rapidly increasing, and this research field has related to other mathematical topics such as finite group theory, association schemes, and formal verification. As the field of card-based cryptography expands rapidly, it is becoming harder to even find unsolved problems, and this makes it difficult to enter the field for new researchers. In order to further develop the field, this research project aims to organize open problems and new research directions on card-based cryptography to make it easy to enter the field. |
