Applying d-RSA with login system to speed up decryption process in client side 将d-RSA应用于登录系统,提高客户端解密速度
Kritsanapong Somsuk, N. Thammawongsa
Login System is the important process to identify the right for accessing the application by identifying and authenticating. Usually, username and password are the personal details of user for accessing the system. However, if both of them are stolen over the insecure channel, then the system is broken. With this problem, some of cryptographic algorithms are chosen to apply with the login system to avoid breaking the system. In the beginning of this year, the strong login system was proposed by applying with two different cryptographic algorithms, RSA and One Time Pad (OTP). RSA which is the asymmetric key cryptosystem is chosen for exchanging the OTP's key. One the other hand, user's password will be protected by using OTP. Although the improved login system is very strong and is very difficult for attackers to trap the information, the speed becomes very slow especially the decryption process of RSA taking very high computation time. In this paper, the new modified login system is proposed to speed up the login process with the same security level when it is compared with the login system applying with RSA and OTP. In fact, d-RSA is chosen instead of RSA by choosing the new private key with the lower Hamming weight in comparison to the private key. In particularly, with the lower Hamming weight, it implies that the new modified login system applying with d-RSA and OTP is faster than the login system with RSA and OTP. The experimental results show that the new modified system can speed up the login system although it becomes slower in registration process. The reason is that in registration process, it must also take time to find the new private key with the lower Hamming weight. However, the registration system is the process that will be implemented only the first time for user to sign up the application.
登录系统是通过识别和认证来确定访问应用程序的权限的重要过程。通常,用户名和密码是用户访问系统的个人详细信息。然而,如果它们都通过不安全的通道被窃取,那么系统就会被破坏。针对这个问题,选择一些加密算法应用于登录系统,以避免破坏系统。在今年年初,强登录系统提出了应用两种不同的加密算法,RSA和一次性Pad (OTP)。在交换OTP的密钥时,选择了非对称密钥密码系统RSA。另一方面,使用OTP可以保护用户的密码。虽然改进后的登录系统非常强大,攻击者很难捕获信息,但速度变得很慢,特别是RSA的解密过程需要很高的计算时间。本文提出了一种新的改进的登录系统,与采用RSA和OTP的登录系统相比,在相同的安全级别下,提高了登录过程的速度。实际上,选择d-RSA而不是RSA是通过选择与私钥相比具有较低汉明权重的新私钥来实现的。特别是,由于Hamming权重较低,这意味着应用d-RSA和OTP的新修改的登录系统比使用RSA和OTP的登录系统更快。实验结果表明,改进后的系统虽然在注册过程中速度变慢,但可以加快登录系统的速度。原因是在注册过程中,也必须花费时间来寻找具有较低汉明权重的新私钥。然而,注册系统是用户第一次注册应用程序时才会执行的过程。

A method of cloud and image-based tracking for Indonesia fruit recognition 基于云和图像的印尼水果识别跟踪方法
R. Agushinta, H. Medyawati, Ihsan Jatnika, Hustinawaty
Rapid technology development is proved by calm technology usage and people with different ages, starting from children to adults. Technology is a tool to facilitate someone who does her/ his work so it is often used as a medium for giving information about anything, transportation, type of disease, types of fruits for the society, etc. Augmented Reality (AR) is a variation of Virtual Environments (VE), or well known as Virtual Reality (VR). VR technology allows users to join a virtual environment. The main purpose of AR is to create a modern environment by combining real and virtual environments' interactivity so the users feel that the environment created is real. By the help of AR technology (such as computing vision and object recognition), the real environment around will be able to interact in digital form (virtual). Information about the environment and the object can be added to the AR system which then that information showed on the real-world screen in realtime as if the information is real. The expected result is the application produced will be in line with the purpose of research. Three-dimension object can be appeared, exposing various information on the fruits types that can be felt directly by the support of multiple sensors located on AR mobile devices. The acknowledgment of fruit is often published and introduced to the public in a conventional way such as books, advertisements, brochures or by using the web. Unfortunately, these make people less motivated to dig more information about the fruit and even some of them who do not know the fruit by type. Therefore, one innovation will create a way of delivering fruit recognition information with Augmented Reality technology.
从儿童到成人,不同年龄段的人对技术的平静使用证明了技术的快速发展。技术是一种工具,方便某人做她/他的工作,所以它经常被用作提供任何信息的媒介,如交通、疾病类型、社会水果类型等。增强现实(AR)是虚拟环境(VE)或众所周知的虚拟现实(VR)的一种变体。VR技术允许用户加入虚拟环境。AR的主要目的是通过结合真实和虚拟环境的交互性来创造一个现代的环境,让用户感觉到所创造的环境是真实的。借助AR技术(如计算视觉和物体识别),周围的真实环境将能够以数字形式(虚拟)进行交互。有关环境和物体的信息可以添加到AR系统中,然后这些信息就会实时显示在现实世界的屏幕上,就好像这些信息是真实的一样。预期的结果是产生的应用程序将符合研究的目的。可以出现三维物体,通过位于AR移动设备上的多个传感器的支持,可以直接感受到水果类型的各种信息。对水果的认可通常以传统的方式出版并向公众介绍,如书籍、广告、小册子或使用网络。不幸的是,这使得人们没有动力去挖掘更多关于这种水果的信息,甚至有些人不知道这种水果的种类。因此,一项创新将创造一种利用增强现实技术传递水果识别信息的方式。

F. Shaikh, Sheroz Khan, Z. Zaharudin, A. Alam, M. Yaacob, Z. Shahid, Farah Diyana Bt. Abdul Rahman, K. Badron
In this ultra-wideband antipodal Vivaldi antenna among end fire radiation patterns function at UWB (3.1 GHz to 10.6 GHz) frequency range for radar and microwave imaging application is proposed. This article presents the design of two different types of antipodal Vivaldi antennas, a conventional and a modified antipodal Vivaldi antenna. This paper presents a parametric analysis of each antenna. While designing the proposed antennas, originally a conventional antipodal Vivaldi antenna is presented for a wide impedance bandwidth performance assessment. Furthermore, the Vivaldi antenna is modified by incorporating corrugations on the edges which resulting in gain significantly along with increased directivity in the low frequency band. In addition, the modified antenna offers high gain and flat gain in the operating UWB band. The design and optimization process is carried out using the CST simulation software for parameters performance assessment of return loss, radiation pattern, directivity and input impedance. Prototypes of the two different proposed antennas are fabricated and tested for its return loss and directional pattern.

A CFD investigation of airflow in a hard disk drive production line to detect the cause(s) of contamination and its mitigation 对硬盘驱动器生产线上的气流进行CFD调查,以发现污染的原因及其缓解措施
Adisorn Khaokom, J. Thongsri, Polsate Kaewkhaw
Contamination exceeds the standards in certain areas within the production line of hard disk drive (HDD) manufacturing, such as in the clean room of a factory. In order to find the cause(s) and solve the problem, we decided to use the computational fluid dynamics (CFD) to simulate the airflow within the production line. The results show the cause of contamination, which is from the exhaust fan installed in the electrical testing machine in the production line of HDD manufacturing, which releases large amounts of particles. To resolve this problem, the CFD results were analyzed to design and create a new cover for the exhaust fan. Once this invention is installed to the electrical testing machine, it can control the airflow to float into other areas that do not affect nor contaminate the product. The factory utilized this research. Other than solving contamination problems that exceed standards, it also saves production costs from purchasing new machines as well.

I. Adam, K. Kadir, Sheroz Khan, A. Nurashikin, H. Mansor
This paper aims to study the performance of all basic inductive resonant wireless power transfer (WPT) topologies for power transfer efficiency, using the effect of circuit topology in affecting the coefficient of coupling. In the study, all the four basic inductive resonant wireless power transfer topologies are analyzed and simulated. The simple T-equivalent circuit is used to represent the system and MATLAB® are used as the backbone in the analysis. The analysis shows that the parallel-to-series and parallel-to-parallel topology configurations give the best power transfer efficiency. The results show that parallel to series and parallel to parallel average power transfer efficiency referring to coefficient coupling (k) are 81% and 80% respectively, compared to the series-to-parallel and series-to-series which are almost 70% accordingly. The study provides evidence of further system analysis for parallel to series and parallel-to-parallel WPT topologies. The results of the analysis would prove useful in furthering insight into its application such wireless battery charging of electric vehicles.

MPC-PID comparison for controlling therapeutic upper limb rehabilitation robot under perturbed conditions MPC-PID控制摄动条件下治疗性上肢康复机器人的比较
Athar Ali, S. F. Ahmed, M. K. Joyo, K. Kushsairy
Increase in the number of stroke patients upsurges the need of rehabilitation robots. It's the ability of human muscles to recover from stroke if it performs certain movements repetitively and robots are the best way to perform repetitive tasks. In this study, a 3 degree of freedom (3DOF) upper limb rehabilitation robot has been developed to recover the patient who have impaired limb, physical trauma or hit by a stroke. In therapeutic exercise robots, the position accuracy and stability are two major concerns, how effectively exercise is being performed and how much stable robot is from external disturbances. To ensure that, an analysis has been performed on a comparison of PID (Proportional integral and derivative) and MPC (Model Predictive Control) control algorithms to find out which control algorithm is most suitable for upper limb rehabilitation robots.

To ensure that, an analysis has been performed on a comparison of PID (Proportional integral and derivative) and MPC (Model Predictive Control) control algorithms to find out which control algorithm is most suitable for upper limb rehabilitation robots.","PeriodicalId":228333,"journal":{"name":"2017 IEEE 3rd International Conference on Engineering Technologies and Social Sciences (ICETSS)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126887487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intense and severe torrents, tornadoes and thunderstorm causes numerous casualties in fraction of second and extreme devastation of infrastructure in many countries. Flash floods are considered one of the most hazardous natural disasters. Several approaches have been made for an authentic and robust early warning system to forecast the flash floods vigorously. An intelligent and vibrant model for the recognition of floods includes the estimation of water level, Global Positioning System-Precipitable Water Vapor (GPS PWV), precipitation velocity, wind speed, direction, upstream levels of river, soil moisture, oceanic bottom pressure and color of the water with accurate and reliable cognition algorithms. UGS (unattended ground sensors) and langrangian micro transducers are deployed on the ground and spread on the sea surface respectively to investigate the hydrological and meteorological differences on real time basis. By the utilization of fuzzy logic, Kalman filtering, Adaptive neuro fuzzy interference system (ANFIS), Particle Swarm Optimization (PSO) and Neural network autoregressive model with exogenous input (NNARX) based structure. Reduction of complexities in data collection, high false alarm rates, communication issues, low WSN battery backup and all related hindrances have been the focal point of this research paper.
强烈和严重的山洪、龙卷风和雷暴造成大量人员伤亡,而对许多国家的基础设施造成的第二次和极端破坏只是其中的一小部分。山洪被认为是最危险的自然灾害之一。为了建立一个可靠而有力的预警系统,对山洪暴发进行了有力的预报,研究人员提出了几种方法。洪水识别的智能动态模型包括水位估算、全球定位系统可降水量(GPS PWV)、降水速度、风速、方向、河流上游水位、土壤湿度、海底压力和水的颜色,具有准确可靠的认知算法。UGS(无人值守地面传感器)和langangian微型传感器分别部署在地面和海面上,实时调查水文和气象差异。采用模糊逻辑、卡尔曼滤波、自适应神经模糊干扰系统(ANFIS)、粒子群优化(PSO)和基于外生输入的神经网络自回归模型(NNARX)的结构。降低数据采集的复杂性、高虚警率、通信问题、低电池备用以及所有相关障碍是本文研究的重点。

Artificial elbow joint classification using upper arm based on surface-EMG signal 基于表面肌电信号的上臂人工肘关节分类
Jicheng Wang, W. Wichakool
This paper proposes a method of elbow joint motions recognition using surface electro-myography (sEMG) signal for disable people with below-elbow amputation. It solves the situation that forearm without muscle cannot control forearm pronation. The pre-processing system processes sEMG signal to remove noise by soft threshold method, then denoising sEMG signal is sent to artificial neural network which trains features to recognize motions. The probability of this method activating 4 motions is 91.78% that was demonstrated by experimental results of recognition motions.
提出了一种基于表面肌电信号的肘关节运动识别方法。解决了没有肌肉的前臂无法控制前臂内旋的情况。预处理系统采用软阈值法对表面肌电信号进行处理,去除噪声,然后将去噪后的表面肌电信号送入人工神经网络,由人工神经网络训练特征进行运动识别。识别动作的实验结果表明,该方法激活4个动作的概率为91.78%。
