Abstract for Research Report	The field of cryptography is often regarded as a single, unified area of research; however, its actual scope is highly diverse. It encompasses a wide range of disciplines, including cryptographic theory, number theory, information theory, computational complexity theory, and quantum information theory, each with distinct mathematical backgrounds and research perspectives. While this diversity constitutes a major strength of cryptographic research, it also presents challenges—particularly for early-career researchers. Research topics and methodologies outside one’s own specialization can easily become “black boxes,” making it difficult to develop interdisciplinary understanding and foster meaningful exchange. In light of this situation, the present workshop aims to provide a platform for sharing how various fields within cryptography and its related areas approach specific research problems, as well as the mathematical motivations and theoretical frameworks underlying their work. Rather than limiting discussions to the presentation of results, the workshop will emphasize explicit discussion of research motivations and underlying theoretical structures, thereby promoting deeper mutual understanding across disciplines. Furthermore, this workshop will actively invite participation not only from researchers in cryptography but also from related fields such as number theory, algebraic geometry, computational complexity theory, and quantum information theory. Through this, we aim to provide early-career researchers with opportunities to develop interdisciplinary perspectives and to situate their own research within a broader academic context. Finally, we expect that the network formed among early-career researchers through this workshop will contribute to the development of new research communities, future collaborative research, and the creation of novel research directions. This workshop aspires to serve as a starting point for fostering interdisciplinary and emerging research in cryptography and its related fields.
