the design decisions made in the architecture of a software system are essential to its maintainability, and thus its quality is of great importance. Architecture smells (ASs) can be used to identify any quality issues within the system. To further explore the relationships between ASs, stability, and reusability, Spearman correlation coefficients will be calculated. This paper seeks to examine the connection between architecture smells, software stability, and reusability. To do this, we utilized a dataset created by other researchers and conducted an empirical study of the associations between five types of architecture smells and software stability and reusability. This research is necessary as there is a lack of in-depth research on architecture smells and their relationship to software stability and reusability. We found a relationship between the presence of Feature Concentration in package and the stability and reusability of the package. Also, package's stability is affected by both Cyclic Dependency and Unstable Dependency. A slight positive correlation has been found between God Class and stability, as well as a very weak negative correlation between Unstable Dependency and reusability. Finally, we found a slight negative correlation between package stability and reusability. © 2024 IEEE.

The increased adoption of Internet of Medical Things (IoMT) technologies has resulted in the widespread use ofBody Area Networks (BANs) in medical and non-medical domains. However, the performance of IEEE 802.15.4-based BANs is impacted by challenges related to heterogeneous data traffic requirements among nodes, includingcontention during finite backoff periods, association delays, and traffic channel access through clear channelassessment (CCA) algorithms. These challenges lead to increased packet collisions, queuing delays, retransmissions,and the neglect of critical traffic, thereby hindering performance indicators such as throughput, packet deliveryratio, packet drop rate, and packet delay. Therefore, we propose Dynamic Next Backoff Period and Clear ChannelAssessment (DNBP-CCA) schemes to address these issues. The DNBP-CCA schemes leverage a combination ofthe Dynamic Next Backoff Period (DNBP) scheme and the Dynamic Next Clear Channel Assessment (DNCCA)scheme. The DNBP scheme employs a fuzzy Takagi, Sugeno, and Kang (TSK) model’s inference system toquantitatively analyze backoff exponent, channel clearance, collision ratio, and data rate as input parameters. Onthe other hand, the DNCCA scheme dynamically adapts the CCA process based on requested data transmission tothe coordinator, considering input parameters such as buffer status ratio and acknowledgement ratio. As a result,simulations demonstrate that our proposed schemes are better than some existing representative approaches andenhance data transmission, reduce node collisions, improve average throughput, and packet delivery ratio, anddecrease average packet drop rate and packet delay.

This paper investigates the gender gap in South Africa's cybersecurity sector and its effects on both the sector and the nation's economic growth. There is a significant shortage of skilled workers in the sector, and women are notably underrepresented. The main research question examines how the gender gap affects the industry's development, innovation, and national security posture, emphasizing the importance of utilizing the nation's talent pool to its fullest capacity to combat the evolving cyber threats. Insights and perspectives on the gender disparity in the cybersecurity sector were gathered through a questionnaire circulated amongst cybersecurity professionals and academics. These participants were chosen due to their knowledge and direct engagement in the subject, which offers valuable insights into the obstacles that women encounter in their workplace. The study highlights a number of problems, including gender stereotypes, a lack of access to education and training, and a non-inclusive workplace culture, that contribute to the gender gap. The paper makes the case that in order to solve these problems and advance diversity and inclusivity in the workplace, all stakeholders must work together to close the gender gap. In order to overcome the gender gap in cybersecurity in South Africa, the study suggests special programs aimed at expanding access to education and training opportunities, promoting gender diversity and inclusivity, and creating a more hospitable and equal work environment. This will boost the country's economic growth and strengthen security against cyberattacks. © 2024 IEEE.

The lack of high-quality public datasets is a major obstacle for the creation of practical and effective intrusion detection systems. Hundreds of new publications dedicated to this topic are released every year, but the majority of researchers have to rely on industry partners to get access to proprietary datasets, or use a handful of 'traditional' synthetic datasets, such as KDD99 or CIC-IDS2017. Due to their age and simplicity of the simulated attacks, these datasets cannot contribute to the detection of intrusions in modern environments. At the same time, newer, advanced datasets, such as OpTC, have been largely ignored by the scientific community. Due to the enormous volume and almost complete lack of documentation, only few authors were able to leverage it for the evaluation of their IDS designs. In this work, we aim to make the OpTC dataset more accessible for modern IDS research by pointing out methodology flaws in prior art, designing a repeatable and documented labeling process, and building the baseline of the environment. © 2024 IEEE.

We present an overview of quantum-safe cryptography(QSC) with a focus on post-quantum cryptography(PQC) and information-theoretic security. From a cryptographic point of view, lattice and code-based schemes are among the most promising PQC solutions. Both approaches are based on the hardness of decoding problems of linear codes with different metrics. From an information-theoretic point of view, lattices and linear codes can be constructed to achieve certain secrecy quantities for wiretap channels as is intrinsically classical-and quantum-safe. Historically, coding theory and cryptography are intimately connected since Shannon's pioneering studies but have somehow diverged later. QSC offers an opportunity to rebuild the synergy of the two areas, hopefully leading to further development beyond the NIST PQC standardization process. In this paper, we provide a survey of lattice and code designs that are believed to be quantum-safe in the area of cryptography or coding theory. The interplay and similarities between the two areas are discussed. We also conclude our understandings and prospects of future research after NIST PQC standardisation.

This paper proposes an improved initialization strategy for the multi-view k-means clustering algorithm based on the adaptive sparse membership and weight allocation multi-view k-means clustering algorithm (MVASM). The method first performs k-means++ clustering on each view to obtain the labels for each view, and then defines a cross-view consistency objective function. The labels and view weights are optimized iteratively, and the subviews are integrated according to the view weights. The integrated view is then subjected to k-means++ clustering. The similarity between the subviews and the integrated view is calculated using the labels, and the weights are solved using gradient descent. After iteration, the center of the subviews is calculated using the labels of the integrated view. Finally, the initialized labels, centers, and weights are brought into the MVASM algorithm for clustering. Experiments on multiple benchmark datasets show that the algorithm proposed in this paper improves the accuracy of four evaluation metrics (ACC, NMI, Purity, Jaccard) by an average of 18.49%, 37.15%, 6.34%, and 14.87%, respectively. © 2023 ACM.
