Authentication In Wireless Sensor Networks

Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2005Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 2005Bu çalışmada önerilmiş veya gerçekleştirilmiş kablosuz duyarga ağları asıllama protokolleri incelenmiş ve ayrıntılarıyla açıklanmıştır. Bu protokollerin olumlu ve olumsuz yanları incelenmiş ve bazı karşılaştırmalar yapılmıştır. Son olarak, tamamıyla gerçeklenmiş olan ilk kablosuz duyarga ağları veri bağı katmanı asıllama protokolü TinySec incelenmiştir. TinySec alınan mesajların asıllanabilmesi için mesajların sonuna kapalı anahtarla hesaplanan ve bir şifreleme algoritmasına dayanan mesaj asıllama kodu eklemektedir. Bu çalışmada mesaj asıllama kodu hesaplanmasında kullanılan şifreleme algoritması ve altyapı değiştirilerek, performans karşılaştırılması yapılmıştır. RC5 ve Skipjack algoritmaları kullanılarak yapılan karşılaştırmalarda RC5 ile yapılan asıllamanın daha hızlı olduğu ve daha az güç tükettiği sonucuna varılmıştır.In this study, a broad range of on going research efforts in authentication within the wireless sensor networks are described in detail. Advantages and disadvantages of the proposed systems are described and some comparisons are made. Finally, TinySec which is said to be the first fully implemented link layer security architecture for wireless sensor networks is discussed. TinySec uses message authentication codes for authentication which are formed by secure hash functions and an encryption algorithm. In this thesis TinySec’s underlying authentication and encryption mechanism is changed and compared by using two different encryption algorithms which are RC5 and Skipjack. It is seen that using RC5 for authentication within TinySec is slightly faster than using Skipjack and it consumes less power.Yüksek LisansM.Sc

Smart Grid Metering Networks: A Survey on Security, Privacy and Open Research Issues

Smart grid (SG) networks are newly upgraded networks of connected objects that greatly improve reliability, efficiency and sustainability of the traditional energy infrastructure. In this respect, the smart metering infrastructure (SMI) plays an important role in controlling, monitoring and managing multiple domains in the SG. Despite the salient features of SMI, security and privacy issues have been under debate because of the large number of heterogeneous devices that are anticipated to be coordinated through public communication networks. This survey paper shows a brief overview of real cyber attack incidents in traditional energy networks and those targeting the smart metering network. Specifically, we present a threat taxonomy considering: (i) threats in system-level security, (ii) threats and/or theft of services, and (iii) threats to privacy. Based on the presented threats, we derive a set of security and privacy requirements for SG metering networks. Furthermore, we discuss various schemes that have been proposed to address these threats, considering the pros and cons of each. Finally, we investigate the open research issues to shed new light on future research directions in smart grid metering networks

RFID Technology in Intelligent Tracking Systems in Construction Waste Logistics Using Optimisation Techniques

Construction waste disposal is an urgent issue for protecting our environment. This paper proposes a waste management system and illustrates the work process using plasterboard waste as an example, which creates a hazardous gas when land filled with household waste, and for which the recycling rate is less than 10% in the UK. The proposed system integrates RFID technology, Rule-Based Reasoning, Ant Colony optimization and knowledge technology for auditing and tracking plasterboard waste, guiding the operation staff, arranging vehicles, schedule planning, and also provides evidence to verify its disposal. It h relies on RFID equipment for collecting logistical data and uses digital imaging equipment to give further evidence; the reasoning core in the third layer is responsible for generating schedules and route plans and guidance, and the last layer delivers the result to inform users. The paper firstly introduces the current plasterboard disposal situation and addresses the logistical problem that is now the main barrier to a higher recycling rate, followed by discussion of the proposed system in terms of both system level structure and process structure. And finally, an example scenario will be given to illustrate the system’s utilization

Cyber Security of Critical Infrastructures

Critical infrastructures are vital assets for public safety, economic welfare, and the national security of countries. The vulnerabilities of critical infrastructures have increased with the widespread use of information technologies. As Critical National Infrastructures are becoming more vulnerable to cyber-attacks, their protection becomes a significant issue for organizations as well as nations. The risks to continued operations, from failing to upgrade aging infrastructure or not meeting mandated regulatory regimes, are considered highly significant, given the demonstrable impact of such circumstances. Due to the rapid increase of sophisticated cyber threats targeting critical infrastructures with significant destructive effects, the cybersecurity of critical infrastructures has become an agenda item for academics, practitioners, and policy makers. A holistic view which covers technical, policy, human, and behavioural aspects is essential to handle cyber security of critical infrastructures effectively. Moreover, the ability to attribute crimes to criminals is a vital element of avoiding impunity in cyberspace. In this book, both research and practical aspects of cyber security considerations in critical infrastructures are presented. Aligned with the interdisciplinary nature of cyber security, authors from academia, government, and industry have contributed 13 chapters. The issues that are discussed and analysed include cybersecurity training, maturity assessment frameworks, malware analysis techniques, ransomware attacks, security solutions for industrial control systems, and privacy preservation methods
