Algorithm for Key Transparency With Transparent Logs
(F1000 Research Ltd, 2024) Mollakuqe, E.; Rexhepi, S.; Bunjaku, R.; Dag, H.; Chukwu, I.J.
Background: Cryptography plays a crucial role in securing digital communications and data storage. This study evaluates the Transparent Key Management Algorithm utilizing Merkle trees, focusing on its performance and security effectiveness in cryptographic key handling. Methods: The research employs simulated experiments to systematically measure and analyze key operational metrics such as insertion and verification times. Synthetic datasets are used to mimic diverse operational conditions, ensuring rigorous evaluation under varying workloads and security threats. Implementation is carried out using R programming, integrating cryptographic functions and Merkle tree structures for integrity verification. Results: Performance analysis reveals efficient insertion and verification times under normal conditions, essential for operational workflows. Security evaluations demonstrate the algorithm's robustness against tampering, with approximately 95% of keys verified successfully and effective detection of unauthorized modifications. Simulated attack scenarios underscore its resilience in mitigating security threats. Conclusions: The Transparent Key Management Algorithm, enhanced by Merkle trees and cryptographic hashing techniques, proves effective in ensuring data integrity, security, and operational efficiency. Recommendations include continuous monitoring and adaptive algorithms to bolster resilience against evolving cybersecurity challenges, promoting trust and reliability in cryptographic operations.

Comprehensive Examination of Network Access, Logging, and Auditing Strategies in Public and Private Institutions: Safeguarding Information Security, Resilience, and Compliance in the Digital Era
(Springer Science and Business Media Deutschland GmbH, 2025) Mollakuqe, E.; Dimitrova, V.; Dag, H.; Atanasovski, S.
This research paper delves into the intricacies of network access and communication, logging, and auditing practices within the contexts of public and private institutions. Network access and communication are vital components of information security, encompassing elements such as access controls, authentication, encryption, and network management. The study explores how institutions manage network access and communication to mitigate unauthorized access and ensure data integrity. Through a series of questions and features, we analyze the varying requirements and restrictions imposed on network accessibility, emphasizing the importance of tailored security measures. Additionally, the paper investigates the logging and auditing mechanisms employed by these institutions. Logging involves recording events within systems or networks, while auditing entails reviewing these logs for compliance and anomaly detection. A comparative analysis reveals similarities and differences in how public and private institutions handle sensitive data, link actions to users, and log successful or unsuccessful accesses. Furthermore, it explores the retention periods for logs, critical for compliance, auditing, and security. The research also highlights the significance of business continuity and disaster recovery plans in both sectors, ensuring data restoration and operational resilience during emergencies. By shedding light on the practices and policies in place, this paper offers valuable insights into the strategies employed by institutions to fortify their information security, resilience, and regulatory compliance in the digital age. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.
