Cryptography & Information Security Laboratories

We make data secure

Our Cryptography and Information Security (CIS) Laboratories embark on a journey to a more secure future for everyone. Directed by NTT Fellow Brent Waters, our goal is to become the premier cryptography research laboratory in the world.

At NTT Research, our CIS lab sees cryptography as essential to a Smart World. As every human being is touched by technology in ways far beyond our current experience, security and privacy protection are at the core of our shared future.

By engaging only, the strongest and most dedicated researchers, our lab focuses on foundational research problems in cryptography to deliver long term impact.

We explore attribute-based encryption, homomorphic encryption, and functional encryption regarding security and privacy. We are the elite in this space, but only by remaining open to discovery in unexpected places. Will quantum play a role? What will we do with blockchain? What we expect to discover along this journey will change what it means to trust.

In this world of massive data usage and sharing, Brent explains why information security is so important and how NTT Research is working to improve it.

Elette Boyle, Senior Research Scientist CIS Lab

Elette’s work is all about sharing and keeping secrets. More precisely, she is a cryptographer focused on fully-homomorphic encryption, which allows the ability to perform computations on encrypted data without prior decryption. More than protecting data only when it is sent or stored, Elette finds ways to safeguard it while it is being used.

Vipul Goyal, Senior Research Scientist CIS Lab

Vipul’s job is to make sure today’s encrypted data remains secure tomorrow. The rise of quantum computing makes his task more daunting, and his work in post-quantum cryptography more essential. His research also explores ways to share data in calculations without exposing confidential information, as in the case with HIPAA-protected medical research.

Pratish Datta, Research Scientist, CIS LAB

The advent of quantum computing will render all of today’s conventional encryption schemes obsolete. Pratish designs and analyzes encryption schemes that work today and will stand up to quantum computing tomorrow.

Justin Holmgren, Research Scientist, CIS Lab

Justin explains the importance of proof systems in encryption and why the CIS Lab is well-suited to developing an upgrade to computer security without fear.

Ilan Komargodski, Research Scientist, CIS Lab

Ilan explains the need for cryptography to meet the challenges data security faces today. Using methods like homomorphic encryption, NTT Research hopes to achieve guaranteed security

Sanjam Garg, Senior Research Scientist, CIS Lab

Sanjam’s focus is on developing general purpose tools for cyber security that can be applied to specific applications. In order to achieve this, it is necessary to take on an adversarial mindset to outsmart the attacker.
