Research ArticleOpen accessIn the keywordsFault-tolerant Distributed Systems with Diagnostics AlgorithmsOleg Viktorov, Afif MghawishTo provide consistent actions in distributed systems with faulty nodes the Byzantine agreement protocol (algorithm) is widely used. In case of using message exchange scheme without authentication the Byzantine agreement algorithm leads to agreement if the number of nodes doesn’t exceed 1/3 of the total number. The proposed algorithms based on diagnostics procedures are used to reach an agreement in … …Journal of Computer Science, Vol. 1, Issue 2 · 19 Oct 2005 · 4,840 accessesView PDFCite

Research ArticleOpen accessIn the keywordsSecure Authentication Technique for Data Aggregation in Wireless Sensor NetworksV. Bhoopathy, R. M.S. ParvathiProblem statement: In Wireless Sensor Networks (WSN), serious security threat is caused by node capture attacks where an adversary gains full control over a sensor node through direct physical access. Approach: This creates a high risk of data confidentiality. Results: We propose a secure authentication technique for data aggregation in WSN. During first round of data aggregation, the aggregator upon … …Journal of Computer Science, Vol. 8, Issue 2 · 24 Jan 2012 · 7,286 accessesView PDFCite

Research ArticleOpen accessIn the abstractDesign and Implementation of a Smart File Cabinet System With Enhanced Security and Remote AccessAdebayo Afeez Oluwagbenga, Mustapha Favour, Adebiyi Temidayo Daniel et al.In an era increasingly defined by digital interconnectivity, the physical security of sensitive hard-copy documents remains a persistent vulnerability in organizational infrastructure. Traditional filing cabinets, relying on passive mechanical locks, lack the capability for real-time monitoring, remote access control, or active intrusion detection. This research presents the design and validation of a Smart File Cabinet (SFC) system that bridges this … …Journal of Mechatronics and Robotics, Vol. 10, Issue 1 · 25 May 2026 · 1,696 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Lightweight and Privacy-Preserving Biometric Authentication Framework for Sustainable IoMT SystemsSaima Anwar Lashari, Mahmood A. Al-Shareeda et al.Biometric authentication provides secure, identity-bound access control for the Internet of Medical Things (IoMT), crucial for wearable, implantable, and ambient devices. However, the inherent immutability and sensitivity of biometric data pose severe privacy risks in the event of a breach. Furthermore, conventional public-key cryptography is often too computationally intensive for resource-constrained IoMT hardware. To address these challenges, this paper proposes … …Journal of Computer Science, Vol. 22, Issue 1 · 9 Feb 2026 · 1,924 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnonymous and Distributed Authentication for Peer-to-Peer NetworksPasan Tennakoon, Supipi Karunathilaka, Rishikeshan Lavakumar et al.Well-known authentication mechanisms such as Public-key Infrastructure (PKI) and Identity-based Public-key Certificates (ID-PKC) are not suitable for integration in a Peer-to-Peer (P2P) network environment, the reason being either the lack of or the difficulty in maintaining a centralized authority to manage the certificates. Authentication becomes even harder in anonymous environments. In this study, we present three authentication protocols such that … …Journal of Computer Science, Vol. 19, Issue 1 · 3 Jan 2023 · 6,539 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Classified Protection Protocol for RFID-based Medical SystemsXueping Ren, Ming JiangRFID technology has been used in many medical systems. The data transmitted in these medical systems is very important and sensitive. The security of these private data has a wide range of risks. Most existing protocols lack the idea of classified security protection for RFID-based medical systems. These protocols are difficult to apply directly.
