The Center for Research and Development on Secure Computer Systems (CRADSEC), was established in April 2025 under the Data Science Collaborative Support Unit, currently, Co-creation Center for Future Science Systems (CCFSS), of the Research Organization of Information and Systems (ROIS), Japan. ROIS comprises four national institutes, including the National Institute of Informatics, and one collaborative support unit, CCFSS. ROIS-CCFSS serves as a strategic hub that connects those who develop AI with those who use it, fostering collaboration across disciplines and organizations to pioneer new research fields and academic infrastructure for the AI era. Within ROIS-CCFSS, CRADSEC advances research on secure and trustworthy computer systems that support secure data sharing and data science, providing a technological foundation for the responsible use of AI and data across society.

Overview
We aim to realize a unified TEE architecture that can flexibly operate across diverse platforms ranging from IoT devices to the cloud. This architecture will allow the selection of appropriate enclave configurations and protection mechanisms according to specific requirements and threat models, while taking into account trade-offs among security, performance, and energy consumption.
From the hardware perspective, we will provide highly versatile TEE primitives. Using these primitives, system software will be able to flexibly configure protection domains. From the theoretical perspective, we will develop formal verification techniques to ensure that the protection domains built on top of the TEE primitives are provably secure against the assumed threat models.
Furthermore, we will develop a software environment that enables secure execution of advanced cryptographic operations on the proposed TEE. As a proof of concept (PoC), we will prototype applications that realize secure data distribution.
All developed artifacts will be released as open source including hardware IPs.
