The International Association for Cryptologic Research has awarded a “Test of Time” award to a paper co-authored in 2005 by Brent Waters, currently an NTT Research Distinguished Scientist, and Dr. Amit Sahai, professor of computer science at the UCLA Samueli School of Engineering. Titled “Fuzzy Identity-Based Encryption,” this paper introduced attribute-based encryption, a departure from […]

A paper that Dr. Amit Sahai and I wrote fifteen years ago recently received some attention. Every year, the International Association for Cryptologic Research (IACR) looks back 15 years and selects three papers presented at its events that have proved to have had an enduring impact. This year the IACR honored our paper “Fuzzy Attribute-Based

The field of quantum information systems is complex and multi-disciplinary. The interrelated subject areas are all challenging enough to understand in the first place. Academics and other researchers are also taking several differing approaches to what is commonly called quantum computing. NTT Research Director of Strategy, Kei Karasawa, recently took some time out to provide

The National Science Foundation (NSF) recently released news impacting one of our labs, and quite possibly the future of computing and information technologies. The NSF’s Directorate for Computer and Information Science and Engineering (CISE) granted a major award to Stanford University’s Department of Applied Physics in support of its work to gain a deeper understanding

Last week, I attended the RSA 2020 cybersecurity conference in San Francisco with colleagues from NTT Ltd. It’s an impressive event. With more than 500 sessions and 29 keynote presentations, the event is impossible to capture in a brief post. Let me instead share what were my own top 5 takeaways: Cryptography. As president and

The Hudson Institute, a Washington D.C.-based think tank, hosted a conference on January 17 to address the question of how the U.S. and Japan can collaborate on scientific and technical challenges posed by the rise of quantum computing. NTT Research PHI Lab Director Dr. Yoshihisa Yamamoto participated as a panelist at the one-day event. Known

In mid-November, NTT Research issued a press release announcing that the PHI Lab, which I direct, had reached five-year joint research agreements with eight other research organizations: six universities, one U.S. government agency and one quantum computing software company. In this brief article, I would like to describe some of the background behind this initiative

Basic research is measured in years, even decades, rather than weeks or months. All the same, we have hit a fairly fast pace here at NTT Research in our first half year, given progress in each of our three laboratories. Here’s a quick summary. First, we struck an Industrial Partnership between our Cryptography and Information

In June 2019, NTT Research Distinguished Scientist Brent Waters was named a Simons Investigator in Theoretical Computer Science. Each year, the Simons Foundation supports theoretical scientists in the fields of Physics, Mathematics, Astrophysics and Computer Science and their home academic institutions with significant research support for five years. Dr. Waters is a Professor in the

One of the expressions we use to describe our mission here at NTT Research is that we aim to “upgrade reality.” That’s an ambitious goal, and one that we cannot accomplish by ourselves. The joint research agreement between MEI Lab, which I direct, and the Technical University of Munich (TUM) is a good case in

When we opened our doors in July as a different kind of Silicon Valley startup, I knew there would be plenty of opportunities going forward to explain who we are and what we do. One such occasion took form in the “CIO San Francisco” event in early November. It was a forum that allowed me
