In learning through direct experience, students do not just observe, but also involved in actions and are responsible for the results. Based on the results of observations during class 1B MIN 3 Demak, students had difficulty in understanding the material presented by the teacher. Because the grades obtained by students in class 1B MIN 3 Demak are still below the KKM, which is 6.5, while the class average is 63.68. Therefore, we need to use learning media that full of games to lead student activity. One of the things that can be done by the teacher is the use of flashcards as a learning medium. Data collection techniques were carried out by (1) observation (observation), and (2) tests. Furthermore, the data analysis techniques used in this study are critical analysis and descriptive comparative analysis. The results showed that there was an increasing in student learning outcomes through the use of flashcard media, which was indicated by the ability to read in the Pre-Cycle, the average score reached 63.68 to 71.00 in Cycle I and 82.16 in Cycle II.

For many years, user authentication relied on “something that the user knows,” also known as knowledge-based user authentication. However, recent research indicates that knowledge-based user authentication is no longer considered secure or convenient for mobile users because it imposes several limitations. These limitations highlight the need for more secure and user-friendly user authentication methods. One promising solution is user authentication based on “something that the user is,” which includes authentication methods that use physical characteristics of the mobile user (i.e., physiological biometrics) or their involuntary actions (i.e., behavioral biometrics). Although physiological biometrics have been successfully deployed for mobile user authentication over the last years, recent studies suggest that they show several weaknesses (e.g., vulnerable to various attacks such as impersonation). Consequently, experts in the security field are now focusing more on user authentication based on behavioral biometrics. Therefore, the aim of this work is to investigate the benefits, as well as the limitations of behavioral biometrics for mobile user authentication in order to provide a foundation for organizing research efforts toward the design and development of proper user authentication solutions based on behavioral biometrics for mobile devices.","PeriodicalId":31737,"journal":{"name":"Edutech","volume":"9 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75219852","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}

Overwhelmed controller instances or underutilized instances could reshape their workloads by exchanging their load, i.e., switches that they control. To safely implement this exchange procedure, switch migration protocols are being used. As the migration procedure pauses processing new flows for a few milliseconds, these protocols are designed to be as fast as possible. Faster protocols add to the agility of the network to rapidly cope with the changing demand. In this paper, we introduce a general framework, called Meta-Migration, which focuses on expediting the existing time-sensitive controller load migration protocols. Based on the observation that these protocols impose low overheads on the involved parties, we modify them in a way that they can run in parallel toward multiple candidate destinations. Unlike the usual Fixed protocols that have to decide their destinations before running the protocol, here we rely on the real-time probes that we obtain from multiple systems and commit to only one of them in the middle of the procedure. Typically, migrations can complete on sub-second timescales, but sudden traffic bursts or system-level glitches can significantly slow down these protocols. We observe that by using Meta-Migration, we can dramatically diminish these negative effects. We show theoretical justifications for why this approach improves the overall performance of the migration, namely, its mean finishing time, and the tail latency of the migration. In addition, by developing a distributed controller simulator over real physical devices, we thoroughly measure the effectiveness of this approach as well as its incurred overheads. Our testbed results show up to a 53% tail reduction in the migration time.","PeriodicalId":31737,"journal":{"name":"Edutech","volume":"114 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72554463","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}

As the number of application setups across multiple clusters and different clouds is increasing, technologies that enable communication and service discovery between the clusters are emerging (mainly as part of the Cloud Native ecosystem). In such a multi-cluster setting, copies of the same microservice may be deployed in different geo-locations, each with different cost and latency penalties. Yet, current service selection and load balancing mechanisms do not take into account these locations and corresponding penalties. We present MCOSS, a novel solution for optimizing the service selection, given a certain microservice deployment among clouds and clusters in the system. Our solution is agnostic to the different multi-cluster networking layers, cloud vendors, and discovery mechanisms used by the operators. Our simulations show a reduction in outbound traffic cost by up to 72% and response time by up to 64%, compared to the currently-deployed service selection mechanisms.","PeriodicalId":31737,"journal":{"name":"Edutech","volume":"37 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85798658","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}

Current deep learning (DL)-based encrypted network traffic classification approaches rely on protocol-specific features (e.g., TLS headers) and/or assume that the classification categories (i.e., applications) remain constant over time. However, both the encryption protocols and applications continue to evolve. Therefore, DL models must be retrained from scratch for newer encryption protocols or applications, which makes existing approaches intractable in practice. In this paper, we propose novel Transfer Learning (TL) approaches for introducing new traffic classes to DL models without retraining them from scratch. We also propose a framework named FSTC, which leverages Active Learning (AL) to achieve human-assisted TL for new traffic classes and minimizes the labeled data needed for encrypted network traffic classification. We evaluate our TL and AL approaches using protocol-agnostic features from the publicly available ISCXVPN2016 and QUIC datasets.

Crowd-sourced data collection systems rely heavily on a secure and efficient consensus algorithm. However, consensus algorithms are often considered a bottleneck for scalability. With the emergence of blockchains, proof-of-work (PoW) has become the most popular and secure consensus algorithm for open and asynchronous distributed networks. However, PoW has been criticized for its energy consumption and waste of resources. To address this issue, alternative consensus protocols such as proof-of-stake (PoS) and proof-of-authority (PoA) have been proposed. Reputation-based consensus algorithms have recently gained attention but suffer from limitations in terms of privacy and predictability. In this paper, we propose a privacy-preserving proof-of-reputation (PoR) mechanism that combines ring signatures and dlog-based zero-knowledge proof systems. The proposed PoR algorithm aims to build unpredictable blockchain consensus algorithms that are privacy-friendly for permissioned blockchains. We describe the main algorithms used in PoR, demonstrate their security, and evaluate their performance through an experimental study. We conclude by discussing how these algorithms can be scaled to permissionless blockchain settings.","PeriodicalId":31737,"journal":{"name":"Edutech","volume":"11 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88748695","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}
