Secure Communication Infrastructure for Mobile Computing

Abstract: OVERVIEW: The business operations of companies are becoming increasingly centered around data systems and networks as the informationoriented society continues to evolve. User demands are no longer confined to the conventional office-centered environment, but now are being extended to business operations in the field as well. For example, today’s users are asking for the capability to (1) access enterprise databases from the field to obtain client and inventory information, and for the ability to (2) transmit e-mail and status reports from home to the office for additional efficiency. Meanwhile, all the elements needed to meet these demands are now becoming available with the development of compact, lightweight, powerful portable terminals; the availability of basic and application software for portable terminals; the deployment of mobile telecom infrastructure technologies; and the growing attention of the business community to the potential of mobile computing. But in order to build a seamless computing system environment that supports mobile computing, a mobile environment must be constructed that compares favorably with the enterprise LAN environment in terms of (1) faster transmission bit rates, (2) enhanced security, and (3) adequate assurance of Internet addresses for mobiles. To provide solutions to these and other issues and to propose a mobile computing environment based on optimum security, Hitachi offers a wide product range of portable terminal equipment and other hardware products as well as software products. Hitachi is developing and deploying a system that provides a robust communications platform supporting secure mobile computing based on leading-edge communications and security technologies.

INNOVATION IN MOBILE CLOUDS - Analysis of an Open Telco Application

Abstract: Cloud computing is emerging in several ICT areas, including the mobile services industry. This development is known as mobile cloud computing (MCC). MCC may save mobile energy consumption and be utilized to overcome the fragmentation challenges of application developers, who must take into account various mobile operating systems. This paper introduces a novel mobile-device-independent development approach. Mobile applications will be placed into a cloud and will utilize open application programming interfaces from the telecom infrastructure. This approach, called Open Telco, enables application deployment that is fully based on cloud-computing principles. In this study, we present a business model analysis of an application case called Event Experience, using the Service, Technology, Organization, and Finance (STOF) framework.

Blockchain-Based Reliable Traceability System for Telecom Big Data Transactions

Abstract: Telecom big data generated by telecom networks have a high economic value. Thus, telecom operators actively explore telecom big data transactions methods to minimize the possibility of leaking users’ privacy. The existing solutions do not allow the data sets to leave the database, instead only allow the buyers to send data mining algorithms to the telecom operator’s platform for training. However, this centralized platform has a high risk of tampering. In addition, the currently existing solutions cannot be used to accurately and quickly trace the information of telecom big data transactions. To address these limitations, we propose a blockchain-based reliable traceability system for telecom big data transactions using smart contracts and the InterPlanetary File System. Two types of smart contracts are developed to store transaction information for tracing. Access control strategies and a reapproval prevention strategy are designed for ensuring the safe operation of the system and avoiding the problem of favoritism and fraud. We use Ethereum as a verification platform to develop and evaluate this system. The implementation of functions, such as purchasing data sets, sending algorithms, obtaining results, and tracing transactions in the smart contract and the implementation of the proposed strategies are verified. The results demonstrate that the performance of the proposed system is better than the existing solutions, and the traceability response time is improved to the order of seconds, so as to realize the safe and efficient traceability of telecom big data transactions. In addition, Ethereum and Hyperledger Fabric v0.6 were discussed to provide insights for future development.
