In his inaugural article as a Forbes contributor, NTT Research President and CEO, Kazuhiro Gomi, notes that the field of encryption, a key component of any cybersecurity framework, is evolving. One current development is associated with Attribute-Based Encryption (ABE), an approach proposed fifteen years ago by Drs. Amit Sahai and Brent Waters. Dr. Sahai is […]

One of the first decisions of CIS Lab Director Dr. Tatsuaki Okamoto was to ask Brent Waters, professor of computer science at the University of Texas, Austin, to join NTT Research as a Distinguished Scientist. He did so in July 2019.  Since then, Dr. Okamoto has built an impressive team, with eight in cryptography, and

It’s fair to say that our three labs are engaged in fundamental research. Another way of putting it is that they are trying to overcome serious obstacles, or even out-think a dedicated opponent. Our CIS Lab is working within the context of cyber threats. Our MEI Lab is in a long-term fight against disease and

In May, NTT Research announced that Joe Alexander, M.D., Ph.D., had joined its Medical and Health Informatics (MEI) Lab as a Distinguished Scientist. Dr. Alexander, who is also a Fellow of the American College of Cardiology, joined NTT Research after more than two decades in the pharmaceutical industry. He had previously spent eight years at

When I joined NTT Research as president and CEO last summer, I didn’t expect to be getting into the movie business. After all, we set up operations in Silicon Valley, not Hollywood. But a few months after we got started, our team knew we were going to need some help in explaining our mission to

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
