Abstract

Lumban Pea Timur is one of the villages in Balige District, Toba Samosir Regency, North Sumatra Province. Village development is currently inseparable from the support of information technology, almost every village requires information technology to improve services to the community. The process of conveying information by the village to the resident, namely from the sub-district head to the village head reaches the resident. Processes like this often lead to inaccurate information. All existing regional potentials must be disseminated to show their superiority. Each district has an area called a sub-district and village. The rapid development of the world of communication technology has had a tremendous impact on the pattern of people’s lives. Information systems have made people’s lives dynamic and fast. With the facilities provided, encourages people to take advantage of information and communication technology to assist in their daily activities. The village government of Lumban Pea does not yet have a website address. This has resulted in information owned by the village that cannot be accessed by the wider community, causing this village to be very left behind. In this increasingly advanced technological era, a website-based information system can be implemented in East Lumban Pea village to overcome the above constraints. With the existence of a village information system, the community can directly access the various kinds of information presented. Likewise, village leaders can directly provide or update information related to the village they are fostering. All forms of information regarding population management can be accessed on the village information system page.

Abstract

Cyber-Physical Systems (CPS) connect computational processes with physical operations and are increasingly used in industrial control, energy management, healthcare, and transportation. This connectivity improves automation and monitoring, but it also creates security risks because attacks on CPS may affect both digital assets and physical processes. Existing intrusion detection approaches based on machine learning and deep learning have shown promising performance, yet many of them provide limited explanation for their decisions. This limitation reduces trust, especially in critical infrastructure environments where security decisions must be understandable. This study proposes a Hybrid Explainable Intrusion Detection System (HX-IDS) that combines Random Forest, Long Short-Term Memory (LSTM), SHAP, and LIME. Random Forest is applied to identify important features, while LSTM learns temporal attack behavior from CPS traffic. SHAP and LIME are used to explain model predictions at global and local levels. The proposed framework is evaluated using benchmark CPS-related datasets. The results show that HX-IDS improves detection performance, reduces false alarms, and provides clearer explanations for security analysts. This study contributes to the development of more transparent and trustworthy AI-based intrusion detection for CPS security.

Abstract

The integration of 5G networks and the Industrial Internet of Things (IIoT) enables real-time industrial automation but also expands the cybersecurity attack surface. Although previous studies have proposed AI and blockchain-based security frameworks, intrusion detection in 5G-IIoT remains limited by black-box AI models, low interpretability, and blockchain mechanisms that mainly support logging rather than attack detection. This study proposes an Explainable Blockchain-Enabled Intrusion Detection System (XB-IDS) for secure 5G-IIoT networks. The framework integrates deep learning-based intrusion detection, SHAP-based explainability, and blockchain-enabled security logging with smart contracts. A hybrid CNN-LSTM model is used to detect spatial and temporal attack patterns, while SHAP provides interpretable explanations for security analysts. Public IIoT cybersecurity datasets such as TON_IoT, Edge-IIoTset, and CICIoT2023 are used for evaluation. The proposed framework is assessed using accuracy, precision, recall, F1-score, false positive rate, detection latency, throughput, and explainability analysis. The proposed XB-IDS aims to improve detection performance, transparency, and trustworthiness in 5G-IIoT security operations. This study contributes an experimentally evaluable framework that extends prior AI-blockchain security research toward explainable and accountable intrusion detection.
