NTT Research has launched its Zero Trust Data Security (ZTDS) Suite, a quantum-secure cybersecurity solution powered by attribute-based encryption (ABE) designed to defend data even against the emerging threat of quantum computing. The suite includes a ZTDS Platform that combines ABE and AI, plus applications for use cases such as document protection, sovereign video security, and AI data safeguarding, with more to follow based on demand. After years of research, NTT’s scientists have resolved the performance constraints that held back real-world deployment of ABE in a quantum-safe context, demonstrating practical Post-Quantum Cryptography–ABE (PQC-ABE) based on standard cryptographic assumptions. “With the exponential development of quantum technologies, governments and security standards bodies are calling on organizations to migrate to a quantum-ready cybersecurity strategy,” said NTT Research President and CEO Kazu Gomi. He added that the suite “ensures critical data will remain secure after quantum capabilities become practical.” Crucially, ZTDS allows fine-grained access control—data decryption depends on attributes such as role, content type, or organization—and preserves this control even if files are exfiltrated, plugging a vital gap in traditional zero-trust architectures.

As Bennett Indart, Senior VP of Technology Development at NTT Research, explains: “Organizations conventionally rely on zero trust architectures … once the data file itself is leaked, the security is breached. ZTDS … maintains access controls … even if the file is copied … Also, quantum computing poses an existential threat to the conventional public key encryption. This new PQC-ABE provides peace of mind for this threat.” The suite also includes crypto-agility software that enables seamless migration from legacy ABE to PQC versions, ensuring compatibility with future security standards. In partnership with Japan’s CRADSEC (Center for Research and Development on Secure Computer Systems), NTT Research will deploy its ABE software within Trusted Execution Environments (TEEs), enabling highly secure cryptographic operations like revocation, with CRADSEC Director Yutaka Ishikawa commenting that TEEs “will flexibly configure protection domains” to support advanced use cases. NTT Research positions its offering as the only commercially available enterprise-grade ABE solution today and remains committed to advancing its performance, feature set, and scalability to serve academia, public-sector, and enterprise customers in a quantum-computing future.
