Paper Solves 20-Year-Old Problem, Sets Theoretical Foundation for Stronger Cryptography
NTT Research, Inc., a division of NTT (TYO:9432), along with UCLA and the University of Washington, today announced that a paper co-authored by cryptographers affiliated with their respective institutions has solved a two-decade-old problem involving indistinguishability obfuscation, the notion of making a computer program “unintelligible” while preserving its functionality. The academic paper, posted on public academic platforms, the Electronic Colloquium on Computational Complexity, the IACR ePrint server and Arxiv, has three co-authors: Aayush Jain, a graduate student researcher in the Center for Encrypted Functionalities (CEF) at the University of California, Los Angeles (UCLA) and research intern at the NTT Research Cryptography and Information Security (CIS) Lab; Huijia (Rachel) Lin, associate professor in the Paul G. Allen School of Computer Science & Engineering at the University of Washington; and Amit Sahai, Symantec Chair Professor of Computer Science at the UCLA Samueli

(Bloomberg) — The board of NTT Docomo Inc. is holding a meeting Tuesday to discuss Nippon Telegraph & Telephone Corp.’s plans to turn its wireless carrier unit into a wholly owned subsidiary, a move that may help Prime Minister Yoshihide Suga’s push to lower phone tariffs.
Pedestrians cross a road in front of an NTT Docomo Inc. store in Tokyo, Japan, on Wednesday, April 24, 2019. Docomo this month cut prices on its mobile phone data plans, some by as much as 40 percent, responding to government pressure to reduce prices that it says are among the world’s highest.
The buyout could be worth as much as 4 trillion yen ($38 billion), based on a 30% premium to Monday’s closing price in Tokyo, the Nikkei newspaper reported earlier. Given that parent NTT already controls 66% of the wireless carrier, any proposal is all but guaranteed to pass. The

Billboard Japan and NTT Data/NTT Data Institute of Management Consulting (NTT Data/IMC) partnered on a new project that combines the former’s chart data and the latter’s neuroscientific technology to develop a new way to analyze music trends.
Billboard Japan’s Hot 100 song chart is based on a weighted formula incorporating eight metrics such as CD sales, downloads, streams and Twitter mentions. NTT Data/IMC is a pioneer in the advancement of the brain information business, in part through its development of the “NeuroAI” that predicts the cerebral activity and perceptual content of people viewing moving images. The underlying technology of NeuroAI was adopted by this year’s AAAI Conference on Artificial Intelligence (AAAI-20).
The collaborative project used technology called “NeuroAI-Music” that simulates the cerebral activity of people listening to music. NeuroAI-Music succeeded in estimating and characterizing the cerebral activity per second of music from audio signals, making it possible to quantitatively extract

Nippon Telegraph & Telephone Corp. plans to turn its wireless carrier unit NTT Docomo Inc. into a wholly owned subsidiary through a tender offer that would be Japan’s largest ever, the Nikkei newspaper reported.
The deal will be announced “soon,” the report said, without citing anyone. The buyout could be worth 4 trillion yen ($38 billion), based on a 30% premium to the closing price in Tokyo on Monday. That would make it the largest tender offer for a Japanese company in history, according to the Nikkei.
NTT already holds 66.2% of the mobile carrier, which is Japan’s largest. Docomo was listed on the Tokyo Stock Exchange’s First Section in 1998 and remains Japan’s sixth biggest company by market value, according to Bloomberg data.
Docomo spokeswoman Saori Yoshimatsu said the company wasn’t the source of the report, and that it had no comment to make at this time. An

PALO ALTO, Calif.–(BUSINESS WIRE)–NTT Research, Inc., a division of NTT (TYO:9432), today announced that it has reached an agreement with the University of Notre Dame to conduct joint research between its Physics and Informatics (PHI) Lab and the University’s Department of Physics. The five-year agreement covers research to be undertaken by Dr. Zoltán Toroczkai, a professor of theoretical physics, on the limits of continuous-time analog computing. Because the Coherent Ising Machine (CIM), an optical device that is key to the PHI Lab’s research agenda, exhibits characteristics related to those of analog computers, one purpose of this project is to explore avenues for improving CIM performance.
The three primary fields of the PHI Lab include quantum-to-classical crossover physics, neural networks and optical parametric oscillators. The work with Dr. Toroczkai addresses an opportunity for tradeoffs in the classical domain between analog computing performance and controllable variables with arbitrarily high precision.
