Cryptography & Information Security Laboratories

Our Mission

Our Cryptography and Information Security (CIS) Laboratories embark on a journey to a more secure future for everyone. Directed by NTT Fellow Tatsuaki Okamoto, 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.

Cryptography and Information Security Lab exists to pursue perfect (ideal) security as the ultimate goal within the context of global commerce and information exchange.

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.

Go Yamamoto, Senior Research Scientist, CIS LAB

Go is on a mission to fix the internet. His research on Blockchain takes advantage of its ability to realize autonomous synchronization without membership in order to give everyone access to all that the internet offers.

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

Brent Waters, Distinguished Scientist, CIS Lab

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.

Tatsuaki Okamoto, Director, CIS Lab

Dr. Okamoto gives an overview of his lab and what they hope to achieve for information security. He outlines his vision and hopes for his lab as well as his researchers.

Shin’ichiro Matsuo, Head of Blockchain Research, CIS Lab

Shin’ichiro explains the significance of Blockchain and why it is crucial to not only financial data security, but also future innovation and development of new business. He also tells us why NTT Research is best suited for this work.

Kei Karasawa VP Strategy, NTT Research

How to bring new advanced technologies to the market? Kei’s goal is to find byproducts of the research being conducted in the labs. Attribute-Based Encryption is one example of how fundamental research can be applied to business and innovation today.

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.
