BSEVOTING: A Conceptual Framework to Develop Electronic Voting System using Sidechain BSEVOTING:一个利用侧链开发电子投票系统的概念框架
Syada Tasmia Alvi, Linta Islam, Tamanna Yesmin Rashme, M.N. Uddin
In a democratic society, a citizen's ability to vote is regarded as one of the most significant legal rights he or she may exercise. For e-voting methods, blockchain presents new possibilities to properly meet transparency, integrity, anonymity and many other security properties. As the need for blockchains keeps rising, demand for bigger, more scalable, more adaptable, and more cost-effective multipurpose chain is also high. Conventional blockchains are incapable of meeting all of these demands. To solve the problems (mostly performance) associated with main blockchains, sidechain technology has recently evolved as a separate chain connected to the main chain that runs in parallel with transactions. Our proposed method is designed to operate on a public blockchain, but we separate the storage of voting information of each candidate using a sidechain to offer a cost-effective blockchain-based voting mechanism by ensuring the security properties such as anonymity, integrity, privacy, security, fairness, receipt freeness and so many. In future, we will broadly discuss and implement this voting system.
在民主社会中,公民投票的能力被视为他或她可以行使的最重要的合法权利之一。对于电子投票方法,区块链提供了新的可能性,可以适当地满足透明度、完整性、匿名性和许多其他安全属性。随着对区块链的需求不断上升,对更大、更可扩展、更适应性强、更具成本效益的多用途链的需求也很高。传统的区块链无法满足所有这些需求。为了解决与主区块链相关的问题(主要是性能),侧链技术最近发展成为与主链连接的独立链,与交易并行运行。我们提出的方法旨在在公共区块链上运行,但我们使用侧链分离每个候选人的投票信息存储,通过确保匿名性,完整性,隐私性,安全性,公平性,收据自由等安全属性,提供具有成本效益的基于区块链的投票机制。未来,我们将广泛讨论和实施这一投票制度。

Experimental Analysis of IPv6 Tunneling of Jumbo Frame Transmission using Mikrotik Routers 基于microtik路由器的IPv6大帧传输隧道化实验分析
Arief Marwanto, Yahya Hidayatullah, Imam Much Ibnu Subroto
In the network testing method, the use of jumbo frames that are applied in tunneling media poses problems if the communication between two points requires a large bandwidth. This paper discusses the analysis of sending jumbo frame packets that are passed through an IPv6-based tunnel using multiple Mikrotik Routers in an actual environment. The test was carried out using two different operating system platforms, i.e. Windows and Linux, by passing jumbo frame packets on an IPv6-based tunnel network using a traffic generator on a Mikrotik Router and having to go through an intermediate router. Jperf/Iperf is used for sending large and continuous data to meet the entire bandwidth capacity and to measure throughput in a network connection. The test results without using a tunnel show that a connection using MTU 4000 produces the largest throughput and takes 0.01 seconds slower, but with a throughput result that is greater than MTU 1500 bytes and MTU 9000. The packets lost when testing MTU 4000 bytes are only experienced once. In the test using tunneling, MTU 4000 produces large throughput by requiring a slightly faster transmission time of 0.01 seconds compared to MTU 1500 but there is no packet loss compared to MTU 1500 and MTU 9000. These results indicate that by using jumbo frames, the best throughput for interconnection between Windows and Linux in IPv6 tunneling based on Mikrotik Router is achieved by an MTU of 4000 bytes.
在网络测试方法中,如果两点之间的通信需要较大的带宽,则隧道介质中使用的巨型帧会带来问题。本文讨论了在实际环境中使用多台microtik路由器在基于ipv6的隧道中发送巨帧报文的分析。测试使用两个不同的操作系统平台,即Windows和Linux,通过使用microtik路由器上的流量生成器在基于ipv6的隧道网络上传递巨型帧数据包,并且必须经过中间路由器。Jperf/Iperf用于发送大且连续的数据,以满足整个带宽容量,并测量网络连接中的吞吐量。不使用隧道的测试结果表明,使用MTU 4000的连接产生最大的吞吐量,慢0.01秒,但吞吐量结果大于MTU 1500字节和MTU 9000。测试MTU 4000字节时丢包只经历一次。在使用隧道的测试中,与MTU 1500相比,MTU 4000需要的传输时间略快,为0.01秒,从而产生了较大的吞吐量,但与MTU 1500和MTU 9000相比,没有丢包。这些结果表明,在基于microrotik路由器的IPv6隧道中,使用巨型帧可以实现Windows和Linux之间互连的最佳吞吐量,最大传输单元MTU为4000字节。

Road Identification using Convolutional Neural Network on Autonomous Electric Vehicle 基于卷积神经网络的自动驾驶电动汽车道路识别
Markus Hermawan, Zaenal Husin, Hera Hikmarika, Suci Dwijayanti, B. Suprapto
Research in the field of autonomous electric vehicle has growth rapidly since they can overcome traffic accidents due to human error. Currently, the method used to identify the road for an autonomous electric vehicle is not in realtime. Thus, this study proposed a method for the autonomous electric vehicle to follow a predetermined route by identifying the road using the Convolutional Neural Network (CNN) as input of the steering control system. The optimal CNN model was obtained using an optimizer of Stochastic Gradient Descent with 150 epoch optimizer that was then used in simulation testing and real-time testing. In simulation testing, from 15 trials conducted, the percentage of success was 93.333%. The success rate to transmit the data from the system to the tool in a real-time manner is 100%. In real-time testing, the autonomous electric vehicle was successfully able to follow the predetermined route accurately. However, the autonomous electric vehicle has not succeeded in avoiding the object in front of it due to the lack of precise steering mechanics and the lack of variation in training data from various conditions that may be passed by the autonomous electric vehicle.
自动驾驶电动汽车可以克服人为失误导致的交通事故,因此在该领域的研究迅速发展。目前,用于自动驾驶电动汽车识别道路的方法并不是实时的。因此,本研究提出了一种利用卷积神经网络(CNN)作为转向控制系统的输入,识别道路,使自动驾驶电动汽车按照预定路线行驶的方法。采用随机梯度下降优化器和150历元优化器获得最优CNN模型,并将其用于仿真测试和实时测试。在模拟测试中,进行了15次试验,成功率为93.333%。将数据从系统实时传输到工具的成功率为100%。在实时测试中,自动驾驶电动汽车能够准确地沿着预定路线行驶。然而,由于缺乏精确的转向机制,以及缺乏自动驾驶电动汽车可能通过的各种条件的训练数据的变化,自动驾驶电动汽车并没有成功地避开前面的物体。

Position Control System of Autonomous Underwater Vehicle using PID Controller 基于PID控制器的自主水下航行器位置控制系统
Ike Bayusari, Albert Mario Alfarino, Hera Hikmarika, Zaenal Husin, Suci Dwijayanti, B. Suprapto
Water covers most of the earth's surface compared to the land, including Indonesia. Such an area can be explored using an underwater robot, which is implemented in an autonomous underwater vehicle (AUV). The AUV control system requires a controller to be able to move properly. Thus, a PID controller that has a simple structure and yields great performance can be implemented in the AUV. This study was conducted to control the movement of the surge, heave, and yaw of the AUV using the PID. The AUV modeling simulations were carried out using Simulink to determine the PID gain values. The simulation results for surge movement were Kp = 38.41, Ki = 10.8 and Kd = 58.4, heave movement were Kp = 49.13, Ki =2.56 and Kd= 107.12 and yaw movement were Kp = 3.18, Ki = 0.18 and Kd = 12.11. The results showed that AUV could perform well and maintain the position determined by the set point for 3–4 seconds.

Impact of Imperfect Channel State Information on Physical Layer Security by Precoding and Diversity 基于预编码和分集的信道状态信息不完善对物理层安全的影响
I. Ajayi, Y. Medjahdi, F. Kaddour, L. Mroueh
Physical layer security (PLS) is an emerging paradigm that makes use of wireless channel characteristics to provide security. Many PLS schemes require knowledge of the channel state information (CSI). However, CSI is usually imperfect due to factors such as noisy feedback channels, channel estimation errors and outdated CSI. In this paper, we investigate the impact of imperfect CSI on the secrecy and error rate performances of a PLS scheme that combines adaptive matched-filter (MF) precoding and diversity in orthogonal frequency division multiplexing (OFDM). Particularly, we derive the secrecy capacity and error rate expressions for the legitimate and eavesdropper's channels under imperfect CSI assumption. The impact of the imperfect CSI is studied via theoretical as well as numerical techniques in frequency-selective Rayleigh fading wiretap channel. The analysis is done in both frequency division duplex (FDD) and time division duplex (TDD) modes.
物理层安全性(PLS)是一种新兴的范例,它利用无线信道特性来提供安全性。许多PLS方案需要了解通道状态信息(CSI)。然而,由于噪声反馈信道、信道估计误差和过时的CSI等因素的影响,CSI通常是不完善的。本文研究了正交频分复用(OFDM)中自适应匹配滤波器(MF)预编码和分集相结合的PLS方案的不完美CSI对保密性和错误率性能的影响。在不完全CSI假设下,推导了合法信道和窃听信道的保密容量和误码率表达式。本文通过理论和数值方法研究了非完美CSI对频率选择瑞利衰落窃听信道的影响。分析采用频分双工(FDD)和时分双工(TDD)两种模式。

Hendra Angga Yuwono, A. H. Saputro, Sabar
The hyperspectral image technology contains information in spectral and spatial forms that produce a huge amount of data. This data becomes an additional load while data is processed. Deep learning is the latest method capable of processing large-scale data with a deep structure of artificial neural network (ANN) and improving the model performance of data analysis. Therefore, this study aims to get a deep learning model into hyperspectral image processing for quantitative measurements of moisture content in dried sea cucumbers study case. The sea cucumber used in this study is the dried sea cucumber (Holothuria scabra), commonly known as Beche-de-mer. This study used the 400–1000 nm wavelength range to measure the moisture content quickly and nondestructively. The proposed model is deep learning which is used to build a predictive model system for moisture content in dried sea cucumbers. The coefficient of determination and the root means square error evaluate the measurement system. The measurement results of moisture content, the coefficient of determination, and the root mean square error values for training data are 0.99 and 0.11%, while testing data are 0.92 and 0.29%.
