NTT Research at the Crypto 2025 Conference

At the Crypto 2025 conference, NTT Research’s scientists are making a splash by presenting 23 impressive research papers. This contribution represents about 15% of the conference’s total accepted papers. The event, held both online and in Santa Barbara, California, is organized by the International Association for Cryptologic Research (IACR). NTT’s participation underlines their robust dedication to bolstering digital security and data privacy—vital concerns in our increasingly digital world.

A notable highlight from NTT’s presentations is the recognition of Senior Scientist Mark Zhandry and Postdoctoral Fellow Omri Shmueli, who won the Best Paper Award. Their groundbreaking work focuses on one-shot signatures (OSS)—a technology that enables the signing of a single contract, effectively preventing future agreements with other parties. This innovation builds on their earlier work and addresses significant challenges in both classical and quantum cryptographic commitments.

Innovative Research and Challenges Addressed

Beyond the award-winning paper, NTT’s contributions span numerous vital areas, including post-quantum secure computational methods and secure key leasing. Papers from the NTT R&D Social Informatics Laboratories delve into key control security for multi-user systems and vulnerabilities in Falcons’ cryptographic system. Their foundational research extends into attribute-based encryption (ABE), with Brent Waters garnering accolades for his transformative work.

Zhandry and Shmueli’s study is particularly significant, solving decade-old problems and setting a standard for future investigations into OSS. Their advancements are crucial in many cutting-edge areas—one-time signature tokens, quantum-supported currency, and decentralized digital currencies, to name a few.

NTT’s robust commitment to cryptographic research is apparent. With 23 papers at Crypto 2025, they confirm their position as leaders in the field, driving innovation and security in digital privacy. To explore more about these ground-breaking contributions, visit the Crypto 2025 official webpage.
