CALL FOR PAPERS The main theme of VCRIS 2025 is the application of cryptography and information security, with a new track of quantum science and technology. The conference aims to provide a platform for exchanging and sharing the latest research in the fields of cryptography, information security, and quantum science and technology. It also offers an opportunity for the publication and dissemination of cutting-edge research through reputable international publishers. As part of the conference, the Quantum Autumn School contributes to raising awareness among scientists, professionals, lecturers, and students about the significance of quantum science and applications. VCRIS 2025 is organized by the Academy of Cryptography Techniques in collaboration with co-organizing institutions including the Vietnam Institute for Advanced Study in Mathematics (VIASM), the Vietnam Association of Faculties-Institutes-Schools-Universities of ICT (FISU), and the Information Security Journal, with the endorsement of the Japan Advanced Institute of Science and Technology, the University of Lorraine, France, and the Computer Security and Industrial Cryptography group (COSIC) of KU Leuven, Belgium.
