Formal Modeling and Analysis of Battle between IoT Malware Mirai and IoT Worm Hajime.


Shingo Yamaguchi

Abstract
 In this paper, we proposed a formal model representing the battle between IoT malware “Mirai” and IoT worm “Hajime". We also analyzed the effect of Hajime by using the model. We regarded the battle as a multi-agent system and express it with agent-oriented Petri net called as Petri nets in a Petri net (PN^2). An advantage of PN^2 is not only as a graphical and mathematical modeling tool but also useful as a simulation tool for the battle. We introduce a lifespan and a secondary infection ability to Hajime in order to turn it to a “white-hat” worm. Our simulation result shows that (i) if the lifespan is too short, Hajime would die out and have no effect. (ii) If the lifespan is too long, Hajime would continue to stay at the infected device even though it completed the defense against Mirai. (iii) The higher the secondary infection ability is, the more effective Hajime becomes.

Trio Adiono

Abstract
 In order to achieve high speed and real-time performance of Visible Light Communication (VLC), we proposed the System on Chip (SoC) Hardware Architecture and its implementation. The SoC architecture is designed to optimally realize OFDM based VLC transceiver system processing. The processor consists of IP blocks design, such as FFT/IFFT, Synchronizer, Modulator, Demodulator etc. Beside throughput, other aspects such as the design size, speed, and design cost will be also considered. The proposed design flow includes the system design modeling, SoC architecture design, SoC Implementation, FPGA based prototyping and system verification. The design covers physical and network layer design. The real-time performance of system implementation in the FPGA will be demonstrated.

Speaker Identification using Power Spectral Subtraction Method.


Win Zaw

Abstract
 Speaker Identification system is the system which allows the user to access the system by making an utterance from the microphone and identifies the current talker out of a set of speakers. In daily life environment, noise is unavoidable and the speech signal recorded from the microphone is corrupted by the background noise. If the input speech signal is contaminated by noise, it happens that the performance and accuracy of the speaker identification system decrease. To solve this problem, power spectral subtraction method is used to eliminate the noise from the noisy input speech signal. In this paper, we emphasized the text-dependent speaker identification system. There are three main modules in the proposed system: background noise suppression, feature extraction and feature matching. Power spectral subtraction with short-time fourier transform (STFT) is used for noise suppression. Mel-frequency Cepstral Coefficients (MFCC) is applied for feature extraction to extract the features from the enhanced speech signal that can later be used to represent each speaker. For feature matching, LBG Vector Quantization (VQ) approach is proposed because it can reduce the amount of data and complexity. The experimental results show that the proposed system is more accurate than the original system and faster in computation than the original one. MATLAB is used for programming to simulate the proposed system.

-Beat Sensors for Monitoring Environments
- IoT Sensors Which Persistently Operate in Environments .



Koichiro Ishibashi

Abstract
 Numerous numbers of IoT sensors could be distributed to environments to persistently monitor the environments and send the acquired data by wireless manner in the era of Trillion Sensor Universe. Therefore, the IoT sensors need to be low cost and low power for operating with energy harvesting power supply. My research group proposes Beat Sensors as low cost, small size, and low-power IoT sensors. The power consumption of the Beat sensors is so small that they can operate even with using an energy-harvesting power supply. We have demonstrated various kinds of beat sensors, such as temperature Beat sensor, power Beat sensor, and Beat sensors for monitoring water quality [3] and so on. We have also demonstrated that data obtained by the Beat sensors are corrected by error correction algorithms even if communication errors often occur, so that substantial communication range become long. We have further shown that the temperature Beat sensor has an advantage in agricultural applications because the growth of plants can be sensed just by counting the number of the ID Beat signals in receivers. In this presentation, Beat Sensors concept and their advantages will be introduced, mainly focusing on monitoring environments. Future plan of the Beat Sensors are also discussed.

Abstract
 The Internet of Things (IoT) has the potential to enable many new applications and bring econxomic benefits. There are, however, many challenges that need to be overcome to make IoT useful. These challenges include security and trust associated with IoT. In this presentation we discuss IoT technologies and applications as well as their security and trust aspects. Subsequently we describe the concept of the blockchain which was originally designed for secure financial transactions. Its cryptographic security benefits, including user anonymity, fault tolerance, transaction integrity and authentication, can be used to enable security and privacy in IoT. We discuss the benefits, limitations and challenges of using blockchain with IoT. We also describe our IoT-blockchain testbed and overview several of our current IoT-blockchain projects for supply chain tracking.

State-of-the-Art in Energy-Efficient Data Centers for Green Cloud Computing


Prof. Nguyen Huu Thanh

Abstract
 Cloud computing has emerged in the recent years as a promising paradigm that facilitates such new service models as Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). These services are becoming more common and require additional network and computing resources. In such paradigm, data centers play a crucial role as they provide the infrastructure for cloud services. Furthermore, data centers nowadays are specifically designed to be extremely over dimensioned in terms of number of servers, switching capacity and of number of deployed links and nodes to guarantee zero-loss and minimum latency packet forwarding. Recent surveys have shown that the energy consumption in a data center considerably contributes to its operation costs. A remarkable part of the large energy volume consumed in data centers today is due to the aforementioned over-provisioning to meet the stringent requirements on reliability. Therefore performance and energy issues are important factors for the design of large multi-tier data centers that can support multiple services.
  The talk is divided into two parts. In the first part, the motivations for current research activities on the areas of Green ICT are addressed. Recent hot research topics for energy-efficient networking, especially green data centers and clouds will also be discussed. In the second part, experiences and research results on the areas of energy-efficient data centers at the Future Internet research group (HUST) will be shared, including energy-aware data center virtualization, energy-aware testbed, protocols and optimization algorithms.

MIMO-based Wireless Power Transfer System for Mobility and Efficiency Improvement


Minoru Okada and Duong Quang Thang

Abstract
 There are great demands for wireless power transfer (WPT) for mobile and IoT (Internet of Things) devices as well as battery charging for moving electric vehicles (EV). Current WPT systems based on near-field coupling have problems in its limitation in the receiver positions and the power transfer efficiency. This presentation introduces WPT with multiple transmitters and receivers, or, a multiple-input-multiple-output (MIMO) WPT system for solving the mobility and efficiency problems in the current WPT systems. Since the proposed MIMO-WPT system deploys multiple transmitters over the area of interest, it is capable of expanding the mobility limitation. WPT using multiple transmitters and receivers could reduce the power transfer efficiency due to mutual coupling among them. We can solve this mutual coupling problem by optimizing the impedance-matching circuit. The proposed MIMO-WPT system achieves higher power transfer efficiency than the conventional single transmitter and receiver based WPT systems
