Sumitomo Electric and the AIST Establish the Cyber Security Cooperative Laboratory - Kansai's First Laboratory Established by a Business Enterprise to Strengthen the Security of Internet of Things (IoT) Products –

Sumitomo Electric and the National Institute of Advanced Industrial Science and Technology (AIST) have established the Sumitomo Electric-AIST Cyber Security Cooperative Laboratory within the AIST Information Technology Research Institute.

This cooperative laboratory has been founded based on the AIST cooperative laboratory system, which was established this April in order to realize accelerated and intensive research and development. The laboratory applies the AIST’s excellent security technologies for our infrastructure and industrial systems and traffic-related equipment, which are some of our main products, and proceeds with research and development to reinforce security. By doing so, the laboratory aims to further enhance the reliability of these products, and to contribute to creating a more stable society. For the AIST, the laboratory is the Knasai’s first cooperative laboratory under the name of a company.

Research Content

The laboratory conducts research on technologies that can guard against cyberattacks, targeting electronics products connected to networks in each business domain of Sumitomo Electric (infocommunications, automobiles, environment & energy, electronics, and industrial materials). In particular, IoT security technology using AIST’s cryptographic technology and technology for highly reliable embedded systems has been positioned as the main technology. To begin with, the laboratory will conduct experiments demonstrating the security of our automobile components and traffic-related equipment, which are main products of ours, as well as the security of our plant manufacturing equipment. By doing so, the laboratory will identify technical problems and proceed with development for practical implementation.

In addition, through such research, the laboratory strives to increase the reliability of the entire secure development process in the manufacturing industry, while working hard on fostering security-related human resources, currently in short supply in Japan.

Special Award Granted from NTT DOCOMO at the Business Partner Kick-off Event

Sumiden Opcom, Ltd., a group company of the Sumitomo Electric Group, was granted the Special Prize in the category of material procurement from NTT DOCOMO, Inc. at the Business Partner Kick-off Event. NTT DOCOMO selects excellent companies from among their domestic and international suppliers, and commends such companies in five categories, including the Best Partner Award, which is given to a company that has contributed to the development of DOCOMO’s business in terms of material procurement. The Special Award was granted to Sumiden Opcom in recognition of the company’s contribution to the development of Premium 4G*1 and LTE*2 through the optical line terminals that the company delivered to NTT DOCOMO. (The terminals concentrate six optical fibers into one through optical wavelength-division-multiplexing transmission).

High-speed communication service that NTT DOCOMO has provided since March last year for mobile phones and tablets. Using LTD-Advanced technology, the service achieves a maximum communication rate of 375 Mbps at the time of receipt.
LTE (Long-Term Evolution): One of the 4G communication standards. A speeded-up version of 3G, the communication standard for third-generation mobile phones

72nd IEEJ Technical Development Award received from the Institute of Electrical Engineers of Japan

Two of our engineers have received a 72nd IEEJ Technical Development Award from the Institute of Electrical Engineers of Japan on the subjects of “development of new low-loss composite wires” and “commercialization of rubber-block-insulated straight splice junction boxes for 275kV CV cables.”

The following are overviews of the subjects:

[Development of new low-loss composite wires]

[Mr. Tomoyasu Omote, from The Kansai Electric Power Co., Inc., Mr. Koji Nagano and Mr. Toshinobu Tsuji, from Sumitomo Electric]

To Send generated electricity efficiently to locations of demand, the losses in transmission lines need to be minimized. With the aim of reducing the electrical resistance of overhead transmission lines, we have developed a new low-loss system of composite wires. These wires are provided with a maximized aluminum cross section as a result of the minimization of the conventional steel core diameter realized by replacing tension-bearing steel cores with lightweight, high-strength carbon fiber. Using these wires allows the electric resistance to be reduced by over 20% with the same outside diameters of conventional wires, securing a mechanical strength that is equal to or greater than that of conventional wires.

[Commercialization of rubber-block-insulated straight splice junction boxes for 275kV CV cables (RBJ)]

[Mr. Hiroshi Suyama, from Chubu Electric Power Co., Inc., Mr. Tadashi Oimo, from Sumitomo Electric, and Mr. Shigekazu Yokoyama, from VISCAS Corporation]

Rubber-block-insulated straight splice junction boxes (RBJ) are already in use for 66-154 kV cables. There are, however, a variety of challenges for RBJs to be adopted for 275 kV power systems requiring still higher reliability. As a result of the joint efforts made by an electric power company and related manufacturers, advanced quality control technology through the various processes from manufacturing to construction has been established, with stable high-quality connection technology having been completed. The first application in Japan of the newly developed RBJ for 275 kV CV cables to a real transmission line has contributed to demonstrating a substantial reduction in the construction period and cost. In addition, applying the quality control technology established this time will substantially reduce any problems associated with actual work execution, which is expected to contribute to enhancement of the reliability of transmission lines.
