Feature Articles: Security Platform Technologies that Support Cloud Business-
 Security R&D Activities for Cloud Services
Abstract
The use of cloud services for handling economically and socially important information is increasing, and in line with this trend, these services have become attractive targets for cyber attackers and have been exposed to more sophisticated cyber threats. Various efforts are underway at NTT to prevent these evolving cyber threats. In this article, we describe the activities of NTT Secure Platform Laboratories to provide safe and secure cloud services to our customers.

The TRX Traceability Platform
Abstract
TRX, which was developed by the NTT Secure Platform Laboratories, is a traceability platform for visualizing various events that occur in a system. A visualization function in the system makes it possible to track operations such as copy and move that are made to files and virtual machine images. This function provides easy and unprecedented understanding of the flow of information within an enterprise. It can be used for file life-cycle management in offices and license management of virtual server operating systems for cloud providers.

Resilient Security Technology for Rapid Recovery from Cyber Attacks
Abstract
Cyber attacks are a constant threat. In addition to taking the conventional—mainly defensive—countermeasures, it is important to do the utmost to control the effects of an attack once it has occurred in order to recover from those effects as rapidly as possible. In this article, we describe the concept of resilient security, present some use cases, and explain the technology that is used.

R&D on Secure Computation Technology for Privacy Protection
Abstract
Demand is growing for a means of securely processing highly confidential data on the cloud. To meet this demand, the NTT Secure Platform Laboratories has developed practical, fast, multi-party secure computation technology that provides both confidentiality and usability. This article presents some background issues concerning this technology and explains efforts to develop the basic mechanism into a commercial product.

Fully Homomorphic Encryption over the Integers: From Theory to Practice
Abstract
Fully homomorphic encryption is a groundbreaking cryptographic technique that allows the processing of data in encrypted form and is likely to have major applications in cloud security. However, significant efficiency improvements are needed before we can hope to put it to practical use. We, at the NTT Secure Platforms Laboratories, have made multiple theoretical and practical advances in the area of fully homomorphic encryption over the integers, which is a particular type of fully homomorphic encryption, and have obtained the world’s fastest implementation of it to date as a result.

Understanding the Coordination Mechanisms of Gaze and Arm Movements
Abstract
We report on the coordination mechanisms of gaze and arm movements in the visuomotor control process. The brain information-processing mechanisms underlying the eyes, arms, and their coordinated movements need to be understood in order to design sophisticated and user-friendly interactive human-machine interfaces. In this article, we first review the experimental research on visuomotor control, primarily from the viewpoints of eye-hand coordination and online feedback control. Then, we introduce our recent experimental studies investigating the eye-hand coordination mechanism during online feedback control. The experimental results provide evidence that reaching corrections that are rapidly and automatically induced by visual perturbations are influenced by changes in gaze direction. These results suggest that an online reach controller closely interacts with gaze systems.

Multiband Antenna Employing Multiple Metamaterial Reflectors
Abstract
NTT Access Network Service Systems Laboratories has proposed and developed a multiband sector antenna for mobile wireless communication systems employing multiple metamaterial reflectors and a multiband radiator that is suitable for areas with limited space. We present in this article a design for a triple-frequency-band antenna that radiates at 800-MHz, 2-GHz, and 4-GHz bands as an example of the proposed antenna.
Global Standardization Activities-
ITU-T FG-M2M Meeting Report
Abstract
The ITU-T (International Telecommunication Union-Telecommunication Standardization Sector) Focus Group on Machine-to-Machine Service Layer (FG-M2M) was established at the January 2012 meeting of the Telecommunications Standardization Advisory Group to study applications of M2M technology in the e-health field. The group held 12 meetings between then and December 2013. This article reports on the results of the FG-M2M meetings.
