BloAC : A Blockchain-based Secure Access Control Management for the Internet of Things

&lt;p&gt;The Internet of Things (IoT) paradigm has widespread applications across many fields in which private and sensitive user or environmental data are sensed and shared. Most present-day IoT applications depend on centralized cloud servers for authentication and access control. Validating the identity of a user and determining the legitimacy of his/her access requests require multiple rounds of data communications over the untrusted Internet, exposing sensitive data to potential attacks. Thus, protecting these data from security and privacy attacks and ensuring legitimate access is imperative. To address this challenge, we adopt an emerging technology called blockchain to propose a decentralized security framework called BloAC. It ensures secure access control in IoT networks without the intervention of the back-end cloud. We have used the Hyperledger Fabric, an open-source, permissioned blockchain platform, for implementing a prototype system using customized attribute-based access control (ABAC) policies. We have performed simulated and real test bed-based experiments to illustrate that BloAC outperforms the cloud server-based access control in latency and scalability. Finally, we conduct a security analysis to formally verify the ABAC policies used in BloAC and establish its robustness against attacks theoretically and using the AVISPA tool.&lt;/p&gt;

A Study on the Effects of SoC Semiconductor Modularization method on Organizational Effectiveness

본 연구는 SoC 칩 개발 방식인 IP 모듈화 개발 형태가 조직효과성에 미치는 영향을 실증 검증을 위해 진행하였다. 이를 위해 각 변수들 간의 모형을 수립하고 가설을 검증을 위해 국내 SoC 칩 설계 개발자들을 대상으로 설문조사를 진행하였다. 수집된 결과를 바탕으로 구조방정식을 통해 미러링 가설, 미스트 효과, 협력, 효과성 등의 관계를 실증적으로 확인하였다. 결과적으로 미스트는 조직효과성에 유의한 영향이 확인 되었고, 미러링의 경우는 의미 있는 영향을 주지 않았다. 협력은 미러링, 미스트와 조직효과성에 대한 부분 매개효과가 확인되었고, IP이용 형태에 따라 부분적인 조절효과 영향을 확인할 수 있었다. 본 연구는 다음의 시사점을 가진다. 시스템 반도체와 같은 첨단 개발 제품은 미러링 형태의 완전한 모듈화가 힘들어 모호한 모듈 경계 형태를 취하게 된다. 이와 함께 반복되는 IP 도입 사용은 개발 업무간 협업이 중요하게 작용되는 것이 확인 되었다. 이 과정에서 미스트가 필수적이지만 효과성에는 부정적이므로 전략적으로 미스트가 고려되어야 한다, 개발자들의 심리적인 동기 부여와 핵심기술 파악이라는 부분을 고려하여 개발 방식을 효과적으로 채택할 것을 제안한다. This study empirically shows the effect of IP modularity on organizational effectiveness in the SoC development industry. A survey was conducted on domestic SoC chip design engineers to establish a model for each variable. Analysis of the results confirmed the relationship between the mirroring hypothesis, mist, collaboration, and effectiveness and that mist, but not mirroring, has significant effects on collaboration and organizational effectiveness. Cooperation was confirmed to have partial mediating effects on mirroring, mist, and organizational effectiveness, and these effects depended on the type of IP used. This study has the following implications. High-tech development products, such as system semiconductors, have ambiguous module boundaries because it is difficult to modularize completely after design changes. In addition, the study confirms that repeated introduction and the use of IP plays an important collaborative role between development tasks. Mist is essential during this process but has negative impacts on effectiveness, so mist should be considered strategically. It is suggested that the development method be adopted based on considerations of the psychological motivations of developers and the identification of core technologies.
Practical Use of ICT course in Libraries: Perspectives of MLISc graduates in Nepal

Although the Central Department of Library and Information Science (CDLIS) was founded in TU 27 years ago, the Masters in Library and Information Science (MLISc) program is less popular among recent graduates. The MLISc program's reputation and significance are dependent on how successfully it has adapted to emerging information and communication technology (ICT). It is an early attempt to assess the MLISc ICT course material, primarily focusing on how applicable it is to real-world professional situations.Working librarians from Nepal participated in a focus group discussion to assess how well the MLISc ICT course applied to their line of work. Participants have suggested that the basic and advanced ICT course topics in the MLISc curriculum should be distinguished clearly. Library automation, digital library software, and other advanced ICT courses are available. However, the library profession places a high value on graduates with a complete understanding of information system architecture, library automation, and digitization services.

A Study on Predicting Performance of Fixed-Income Funds Using Random Forest Models

금융투자 상품을 선택할 때 투자자들은 최적의 포트폴리오를 구성하기 위해 어려움을 겪는다. 본 연구에서는 채권형펀드에 대한 투자자의 포트폴리오 선택을 돕기 위해 1개월 후의 상대적 성과를 예측하는 기계학습 모델을 제안하였다. 연구에서는 2017년 12월 1일부터 2023년 1월 31일까지의 채권형펀드 성과 자료와 국고채 금리, 원 · 달러 환율, 국내 성장률, 소비자물가지수 등 매크로 지표 데이터를 활용하여 랜덤 포레스트 모형을 구축하였고, 이를 통해 예측력을 검증하였다. 본 연구의 결과는 다음과 같다. 첫째, 제안 모델의 예측 결과는 90% 이상의 정확도와 정밀도를 보였다. 둘째, BorutaPy를 이용하여 특성을 선택했을 때 예측력이 상승하였다. 셋째, 교차검증을 통해 모델의 안정성을 확인할 수 있었다. 이전의 학계 연구들은 개별 금융상품의 가격과 수익률을 직접 예측하는 것이 대부분이었지만, 본 연구는 분류기를 활용하여 상대적으로 우수한 성과 그룹을 선택할 수 있도록 가이드를 제공한다. 이러한 점에서 기존 연구들과는 많은 차별성이 있다. 따라서, 본 연구는 투자자들이 채권형펀드에 대한 투자 결정에 간접적으로 도움을 줄 것으로 기대된다. 향후 연구에서는 딥러닝, 서포트벡터머신(Support Vector Machine) 등 다양한 기계학습 모형들과 비교하여 최적의 예측모델을 개발하고, 정확도를 높일 필요가 있다. When choosing financial investment products, investors struggle to construct an optimal portfolio. In this study, we propose a machine learning model that predicts the relative performance of fixed income funds one month out in order to help investors make portfolio choices. To verify the predictive power, we build a random forest model using performance data on fixed income funds from December 1, 2017, to January 31, 2023, as well as macro indicator data such as government bond interest rates, the won-to-US-dollar exchange rate, the domestic growth rate, and the consumer price index. The results of this study are as follows. First, the prediction results show accuracy and precision of more than 90%. Second, prediction power increases when characteristics are selected using BorutaPy, and third, cross-validation confirms the stability of the model. While most previous academic studies directly predict the price and return on investment from individual financial instruments, this study utilizes a classifier to guide the selection of relatively good performance groups. In this respect, it differs from previous studies. Therefore, this study is expected to indirectly help investors make investment decisions about fixed income funds. For future research, it is necessary to develop an optimal prediction model and to improve accuracy by comparing various machine learning models, such as deep learning and the support vector machine.

Kombinasi Algoritma Kriptografi Vigenere Cipher dan SHA256 untuk Keamanan Basis Data

An organization must consider and manage the security of data storage in databases or databases, and special procedures are needed to protect data from various security risks. The problem in this study is that the population data contained in the Girisuko village administrative service information system has not been encrypted or secured. This can pose a risk that the data stored in the database can be intercepted and misused. In this study, the cryptographic technique used was a combination of the Vigenere Cipher and SHA 256 algorithms to secure or encrypt databases, especially population data in the Girisuko village administrative service information system. The text in the database is encrypted using the Vigenere Cipher, and SHA-256 is used to generate a hash value or a random value that is different from the text in the database. Messages will be encrypted using the Vigenere Cipher and then hashed with SHA-256 simultaneously. As a result, it will be difficult for an attacker to decrypt the text stored in the database because they have to break the Vigenere Cipher encryption, and also have to solve the hash value generated using SHA-256. This combination aims to increase security and maintain the confidentiality of messages from attackers. The application of the Vigenere Cipher and SHA to the village administration service information system application with a real-time database works well, as evidenced by the fast running-time of 0.39 seconds the data encryption process uses the Vigenere Cipher with 894,968 keys/second and an analyzed key length of 7 characters then text on population database successfully secured. By conducting this research, it is hoped that it can contribute to improving database system security.

Perbandingan Metode Perhitungan Jarak pada Nilai Centroid dan Pengelompokan Data Menggunakan K-Means Clustering

This study will observe the process of grouping data or forming clusters using K-Means clusters with three methods of measuring distances, namely Euclidean distance, Manhattan distance, and Minkowski distance. Observations are more focused on changing the centroid value and the results of grouping data, as well as the number of iterations required. Experimental data amounted to 20, 30, 40, and 50 pieces of data which were grouped into 2 groups. This research also summarizes the application of K-Means clusters which have been widely used in various fields, including Health, Education, and Disaster. The results of grouping data with the three distance measurement methods are not too much different, namely the highest difference is 2 members of the data on 50 test data. The most iterations on 40 test data use the Euclidean distance, namely 7 iterations, and the least iteration on 20 test data uses Minkowski distance i.e. 3 iterations. On the 50 test data it takes 4 iterations. The amount of test data is not directly proportional to the number of iterations needed to reach the cluster in a stable state.
Flexible Correct-by-Construction Programming

Correctness-by-Construction (CbC) is an incremental program construction process to construct functionally correct programs. The programs are constructed stepwise along with a specification that is inherently guaranteed to be satisfied. CbC is complex to use without specialized tool support, since it needs a set of predefined refinement rules of fixed granularity which are additional rules on top of the programming language. Each refinement rule introduces a specific programming statement and developers cannot depart from these rules to construct programs. CbC allows to develop software in a structured and incremental way to ensure correctness, but the limited flexibility is a disadvantage of CbC. In this work, we compare classic CbC with CbC-Block and TraitCbC. Both approaches CbC-Block and TraitCbC, are related to CbC, but they have new language constructs that enable a more flexible software construction approach. We provide for both approaches a programming guideline, which similar to CbC, leads to well-structured programs. CbC-Block extends CbC by adding a refinement rule to insert any block of statements. Therefore, we introduce CbC-Block as an extension of CbC. TraitCbC implements correctness-by-construction on the basis of traits with specified methods. We formally introduce TraitCbC and prove soundness of the construction strategy. All three development approaches are qualitatively compared regarding their programming constructs, tool support, and usability to assess which is best suited for certain tasks and developers.
