Aruna Kumara B, M. Kodabagi
Email is one of the important means of communication over the Internet. Due to the rapid growth of Internet, usage of email communication for business, personal and other works has resulted into generation of electronic data in exponential order. Applying machine learning techniques on the huge raw data may degrade the performance. Hence, the data has to be prepared for better performance of the machine learning techniques. The preprocessing phase in machine learning applications such as classification, clustering and prediction is intended to reduce the size of data. This paper proposes a new data preprocessing approach for imbalanced data in email classification domain to measure the effects of various preprocessing methods on different machine learning classifiers. Contribution of various preprocessing methods on the imbalanced dataset is discussed. Accuracy analysis reveals that the proposed approach significantly improves the accuracy of all the machine learning classifiers used in this work. The outcome of this work showed that, success rate of logistic regression achieved 90.39% accuracy in the proposed approach.

An Inverse Park Phase-Locked Loop based Control for Multifunctional Grid-Connected SPV System 基于逆公园锁相环的多功能并网SPV系统控制
Sateesh Kumar Adepu, G. M. Prasad, Hareesh Kumar Yada
In this paper, a simple controller is designed based on Inverse Park Phase-Locked Loop (IPPLL) for a multifunctional grid-connected solar photovoltaic system. The proposed IP-PLL tracks the grid voltage signal to estimate phase and quadrature signal generation to estimate magnitude and similarly, IP-QSG to estimate magnitude of load current signal. Implementing this PLL improves the accuracy of tracking the signal and also has filtering capabilities which in-turn improves power quality such as reactive power compensation, harmonic rejection and proper feeding of SPV energy etc. Incremental Conductance (INC) based maximum power point tracking (MPPT) is used for estimating the reference PV voltage signal and power. The IP-PLL based algorithm performs well under change in irradiance, grid disturbances such as sag/swells and also under load perturbations. These multifunctional capabilities of the grid-connected SPV make the overall system to be more efficient. These operating conditions are tested in MATLAB/Simulink platform.
针对多功能并网太阳能光伏系统,设计了一种基于逆公园锁相环的简单控制器。IP-PLL通过跟踪电网电压信号来估计相位,通过跟踪正交信号来估计幅值,IP-QSG通过跟踪负载电流信号来估计幅值。实现该锁相环提高了跟踪信号的精度,并具有滤波能力,从而改善了电能质量,如无功补偿、谐波抑制和SPV能量的适当馈送等。基于增量电导(INC)的最大功率点跟踪(MPPT)用于估计参考PV电压信号和功率。基于IP-PLL的算法在辐照度变化、网格扰动(如凹陷/膨胀)和负载扰动下都表现良好。并网SPV的这些多功能使整个系统更加高效。在MATLAB/Simulink平台上对这些工况进行了测试。

NTRU and RSA Cryptosystems for Data Security in IoT Environment 物联网环境下数据安全的NTRU和RSA密码系统
Ankitha Nandanavanam, Ipsita Upasana, Nanditha Nandanavanam
The massive technological revolution that has taken place and that is going on at a massive rate, has led to zillions of digital information traveling in a communication network. Information traveling in the network needs security and privacy. There are various cryptographic algorithms available today that can secure messages and data being communicated. Symmetric cryptography, though simple, does not provide authorization efficiently. Asymmetric cryptography proves to be more secure as it provides all the components of information security.With the breakthrough development on the Internet-of- Things (IOT), any digital device can become an originator of data. The main concern which arises is how to protect these data. With an accelerated usage of IoT environment, the security of data collected and stored by these devices has become more crucial.In this paper, we discuss two asymmetric algorithms NTRU (Nth degree truncated polynomial ring) and RSA (Rivest- Shamir-Adleman) in context of IoT. RSA is widely used but is heavy on key size and computation complexity. On the other hand, NTRU can give the same level of bit security with comparative key size and very less computational complexity. The captivity of NTRU algorithm lies in the fact that it works on simple polynomial operations. It is a NP-hard problem based on shortest vector problem (SVP) and is secure even for future quantum attacks. In a resource constrained environment like IoT environment, the performance of RSA and NTRU has been analyzed on the various security level parameters, viz. key generation, encryption and decryption time. Furthermore, performance of the various parameters has also been analyzed on various bits size plain text.
大规模的技术革命已经发生,并且正在以惊人的速度进行,这导致了无数的数字信息在通信网络中传播。信息在网络中传输需要安全性和保密性。目前有各种各样的加密算法可以保护正在通信的消息和数据。对称加密虽然简单,但不能有效地提供授权。非对称加密被证明是更安全的,因为它提供了信息安全的所有组件。随着物联网(IOT)的突破性发展,任何数字设备都可以成为数据的发起者。出现的主要问题是如何保护这些数据。随着物联网环境的加速使用,这些设备收集和存储的数据的安全性变得更加重要。本文讨论了物联网背景下的两种非对称算法NTRU (n度截断多项式环)和RSA (Rivest- Shamir-Adleman)。RSA被广泛使用,但其密钥大小和计算复杂度较大。另一方面,NTRU可以用相对的密钥大小和非常低的计算复杂度提供相同级别的位安全性。NTRU算法的局限性在于它只处理简单的多项式运算。它是一个基于最短向量问题(SVP)的np困难问题,即使在未来的量子攻击中也是安全的。在物联网等资源受限的环境下,对RSA和NTRU在密钥生成、加解密时间等各个安全级别参数上的性能进行了分析。此外,还分析了各种参数在不同比特大小的纯文本上的性能。

Air pollution is a menacing issue in this current era. The atmosphere is composed of unwanted, non-efficient respiratory particles that are harmful to humans. The air people breathe is full of harmful contaminated particles resulting in many non-infectious respiratory diseases. The world-threatening COVID-19 pandemic has led the people to care about their personal hygiene and a mask is turning out to be an eminent requirement for every human to prevent the first stage of attack by the deadly coronavirus. Indeed, asthma is turning worse amidst humans, mostly because of these toxic and life-wrenching allergens that coexist in the atmosphere. To realize a knowledge-based sample a design of smart mask is proposed in the paper.

M. Anees, K. Rahul, Santosh Yachareni
This paper presents the study of impact from the conventional voltage based metric in designing SRAM in 7nm and advanced FinFet technology. Voltage based metric doesn’t provide the detail of charges that can be injected into the SRAM bitcell node before the bitcell node starts to flip, whereas current based (N-curve) approach gives a better insight which leads to designing of stable and robust SRAM bitcell. The study includes analyzing of bitcell metrics such as read stability and write ability to compare the voltage and current based approach.

Vikramathithan A C, Sourabh V Bhat, S. R.
Mammogram plays a vital role on cancer detection in the breast. Computerized processing enhances readability of digital mammogram. Impulse noise is one of the major noise which affects mammogram. Duo-median filter is anticipated to removes high density impulse noise. The projected filter checks for impulse noise and replace the pixel value by median of 2x2 neighboring pixel value. Results of proposed algorithm are compared with median filter, adaptive median filter and super mean filter using various parameters such as peak signal to noise ratio and structural similarities for general image and mammogram. The proposed Duo-median shows significantly better result with AMF and SUMF for higher noise percentage.

Edge Data Security for RFID-based Devices 基于rfid的设备的边缘数据安全
Javeria Ambareen, P. M, Tabassum Ara
Radio-frequency identification (RFID) has become a preferred technology for monitoring in industrial internet of things (IIoT) applications like supply chain, medical industry, vehicle tracking and warehouse monitoring where information is required continually. Typical security threats seen in these applications are denial of service (DOS) attack, transmission attack etc. We propose a novel edge data security schema based on spike modulation along with backscatter communication technique to modulate both sensor and identification (ID) information. It is observed that this data encoding schema works well even in a multi-tag single-reader environment. Further, it uses lower power and offers a low-cost solution for Industrial IoT applications.
射频识别(RFID)已成为工业物联网(IIoT)应用中监控的首选技术,如供应链,医疗行业,车辆跟踪和仓库监控等需要持续信息的应用。这些应用中常见的典型安全威胁有拒绝服务(DOS)攻击、传输攻击等。我们提出了一种基于尖峰调制和反向散射通信技术的边缘数据安全方案来调制传感器和身份信息。可以观察到,这种数据编码模式即使在多标签单阅读器环境中也能很好地工作。此外,它使用更低的功耗,为工业物联网应用提供了低成本的解决方案。

Typical security threats seen in these applications are denial of service (DOS) attack, transmission attack etc. We propose a novel edge data security schema based on spike modulation along with backscatter communication technique to modulate both sensor and identification (ID) information. It is observed that this data encoding schema works well even in a multi-tag single-reader environment. Further, it uses lower power and offers a low-cost solution for Industrial IoT applications.","PeriodicalId":113845,"journal":{"name":"2020 International Conference on Smart Technologies in Computing, Electrical and Electronics (ICSTCEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129100445","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}
