Introduction of Evangelists
Here we will introduce you to the Evangelists within NTT Social Informatics Laboratories.
At NTT, the following titles are bestowed on researchers who are actively engaged in Japan and abroad.
The title of "Fellow" is reserved for individuals whose research results have brought global recognition, and the company anticipates that the individual's work will continue to demonstrate a high level of achievement in areas of key research interest to NTT.
"Distinguished Researcher" is a title given to innovative researchers who are recognized both within and outside the company for the excellence of their work. "Senior Distinguished Researcher" is a title given to exceptionally gifted Distinguished Researchers responsible for guiding innovative research or cutting-edge technical development in research areas considered to be important for the NTT Group over the long term.
"Chief Security Scientist" is a title given to individuals who significantly enhance security capabilities through wide-ranging technological and scientific activities that go beyond the NTT Group (global and/or national security measures, national security system design, providing advice and/or drafting operational guidelines, etc.).
"Security Principal" is a title given to individuals with an outstanding record of achievement both domestically and internationally, and who have gained the trust and acclaim of their peers both within and outside the company. "Security Master" is a title given to individuals among Security Principal who accomplish a task of especially lasting impact on international community.

Mitsuaki Akiyama
PhD (Engineering)
Since joining NTT, has been engaged in R&D of counter-cyber attack technologies. Seeks to create effective security intelligence for measures by developing technologies to monitor, detect, and analyze diversifying cyber attacks on an Internet-wide scale. Research themes cover a wide range, including honeypot, Web security, malware analysis, mobile app/device analysis, IoT device/firmware analysis, and usable privacy and security.
Distinguished Researcher/Security Principal
-
Tibouchi Mehdi
Researches various mathematical aspects of public-key cryptography. Seeks to deepen understanding of security of conventional cryptosystems (RSA, elliptic curve cryptography), create foundation for nascent encryption techniques (pairing, quantum cryptography), and design next-generation multifunctional encryption techniques (fully homomorphic encryption, cryptographic multilinear maps).
-
Makoto Iwamura
To fight against cyber attacks, conducts R&D of technologies that elucidate malware functions and threats. In addition, engaged in R&D of reverse engineering, vulnerability analysis, and forensics.
-
Yuhei Kawakoya
I do research on malware analysis by applying advanced program analysis techniques, such as taint analysis or symbolic execution, to real-world problems in practical fields. My goal is to realize full-automatic analysis technologies to understand all functionalities and behaviors of any types of malware.
Distinguished Researcher

Yu Sasaki
Research on cryptography, in particular on symmetric-key cryptosystem
We are developing secure and efficient symmetric-key cryptosystems. We also perform cryptanalysis for internationally standardized algorithms.
-
Ryo Nishimaki
Research on cryptography, in particular, secure computation on encrypted data and functionalities
We pursue theory and construction techniques for encryption, digital signatures, proof systems, and program obfuscation to achieve secure communication and computation.
-
Yosuke Todo
Creation of a foundational theory for symmetric-key ciphers, and design and analysis of specialized symmetric-key ciphers
Researching a foundational theory for symmetric-key ciphers. Evaluates security of symmetric-key ciphers and designs ciphers for specialized purposes.
-
Atsushi Nakadaira
Research on how to create, manage, and leverage information about social relationships
Addresses social issues by exploring the value of data as information about social relationships, and developing ways to manage and leverage it.
-
Atsutoshi Kumagai
Machine Learning for Knowledge Transfer
Aims to develop machine learning algorithms that perform well even without sufficient data by using useful knowledge from various types of different but related data.
Security Principal
-
Takemi NISASE
Involved in NTT-CERT activities as member of NTT Group's CSIRT (Computer Security Incident Response Team).
As Security System Engineer, seeks to improve NTT Group's overall security level by providing incidence response, security information gathering and analysis, formulating guidelines, and risk analysis. In addition, transfers knowledge gained from these activities to security research.
-
Kazufumi Aoki
I am engaged in the research and development of cyber attack detection technologies and malware analytic technologies. Currently, I am seeking to establish cyber attack countermeasures through R&D of LRR: Platform for Collaborative Cyber Defense and technologies that determine the success or failure of cyber attacks.
