Every distributed system requires a secure environment for its users. security becomes even more important if users exchange sensitive information and value, across the network. An e-commerce environment is an example of a distributed system in which security is of a high priority. It is important that messages are confidential and tamper proof;users cannot repudiate transactions, and only authorized and properly authenticated users can access resources. These functionalities require proper security layer to provide access and sharing functions between the e-commerce systems and their respective customers. A distributed security Management System (DSMS) provides these services/functionalities. The DSMS is a security middleware for e-commerce servers, which coordinates secure communication, access and sharing of resources between the distributed applications, objects, databases and entities that make up the system. It is designed to provide an interface between clients and the databases of the merchants in a secure way, such that authorized clients can retrieve and send information to the system securely. It is required to have high quality and high tolerance for errors since the server is required to be always available continually. It must also have a user-friendly interface and feature set. The DSMS design discussed in this paper provides these requirements using public and private key systems, data encryption standard encryption, log files and a secure hashing algorithm. A prototype of the system was implemented using the Java security platform. (c) 2019 The Authors. Published by Atlantis Press SARL.

As the network continues to become more complex due to the increased number of devices and ubiquitous connectivity, the trend is shifting from a centralized implementation to decentralization. Similarly, strategies to secure networks are increasingly leaning towards decentralization for its potential to enhance security in future networks with the help of Machine Learning (ML) techniques. In this regard, distributed Machine Learning (DML) techniques, such as Federated Learning (FL) and Split Learning (SL), are at the forefront of this shift, offering collaborative learning capabilities across network nodes while maintaining data privacy. However, ML requires vast amounts of dedicated computing, memory, bandwidth, and as a consequence, energy resources. Moreover, resource consumption ML techniques used for network security have mostly been overlooked, which presents a glaring challenge for future networks in terms of overall resource utilization. This research emphasizes the importance of understanding the resource consumption patterns of two important DML techniques, i.e., FL and SL, to analyze the consumption of critical resources when deployed for network security. Furthermore, this research draws important insights from a practical comparative analysis of FL and SL in terms of resource consumption patterns and discusses their scope for future network security, such as in 6G, and stirs further research in this area.

IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY 2014年第6期63卷 2886-2900页

作者： Rengaraju, Perumalraja Lung, Chung-Horng Srinivasan, Anand Velammal Coll Engn & Technol Dept Informat Technol Madurai 625009 Tamil Nadu India Carleton Univ Dept Syst & Comp Engn Ottawa ON K1S 5B6 Canada EION Wireless Inc Ottawa ON K2K 2E3 Canada

Vehicular communications have received a great deal of attention in recent years due to the demand for multimedia applications during travel and for improvements in safety. Safety applications often require fast message exchanges but do not use much bandwidth. On the other hand, multimedia services require high bandwidth for vehicular users. Hence, to provide mobile broadband services at a vehicular speed of up to 350 km/h, Worldwide interoperable for Microwave Access (WiMAX) and Long-Term Evolution (LTE) are considered the best technologies for vehicular networks. WiMAX and LTE are Fourth-Generation (4G) wireless technologies that have well-defined quality of service (QoS) and security architectures. However, some security threats, such as denial of service (DoS), an introduction of rogue node, etc., still exist in WiMAX and LTE networks, particularly in multihop networks. Therefore, strong security architecture and hasty authentication methods are needed to mitigate the existing security threats in 4G multihop wireless networks. Conversely, the network QoS should not be degraded while enhancing security. Thus, we propose QoS-aware distributed security architecture using the elliptic curve Diffie-Hellman (ECDH) protocol that has proven security strength and low overhead for 4G wireless networks. In this paper, we first describe the current security standards and security threats in WiMAX and LTE networks. Then, the proposed distributed security architecture for 4G multihop wireless networks is presented. Finally, we compare and analyze the proposed solution using testbed implementation and simulation approaches for WiMAX. From the simulation and testbed results for WiMAX networks, it is evident that the proposed scheme provides strong security and hasty authentication for handover users without affecting the QoS performance. For LTE networks, we present the theoretical analysis of the proposed scheme to show that similar performance can also be achieved.

The pervasive integration of 'things' in the Internet of Things together with state-of-the-art computer systems provide a stimulating environment for creativity and business opportunities, but also a large range of security challenges. Engineering the security of such systems must acknowledge the peculiar conditions under which such systems operate: low computational capacity, distributed decision-making, significant node churn, etc. These conditions must, therefore, be supported by the techniques and methodologies for building secure and robust IoT systems. With CAAVI-RICS methodology we explore credibility, authentication, authorization, verification, and integrity of IoT and edge computing systems, through explaining the rationale, influence, concerns, and security solutions that accompany them. Our contribution is a complete and detailed systematic categorization and streamlining of security problems, covering the security environment of IoT and edge computing systems. Besides, we contribute to the debate on key aspects of edge computing security and state-of-the-art solutions.

The Internet of Medical Things, (IoMT) requires extensive and intelligent connection, enormous bandwidth, minimal latency, extremely high data rates, and enhanced healthcare experiences. In contrast to the current 5G wireless systems, the next 6G communication system is anticipated to offer Smart IoMT (SIoMT) solutions all over at any moment to enhance people's quality of life. The conceptual structure of 6G networks, their integration with multifaceted networking technologies like wireless optical networks, cell-free communication systems, and quantum telecommunications, in addition to the decentralised protection framework in the context of SIoMT, are presented in this paper. A novel concept for linking households to hospitals, healthcare personnel, healthcare supplies, healthcare facilities etc. will be enabled by such low latency and ultra-high-speed communication networks. The paper also discusses the obstacles and future research directions of installing SIoMT, as well as the needs of 6G wireless networking along with additional important critical approaches. © 2023 IEEE.

The development of electronic voting applications remains an active area of research and this has led to the proposal and implementation of many models based on blockchains. However, most of the proposed models are partially decentralized solutions, in which the blockchain is used as a storage media for votes while the application is written in programming tools such as HTML, CSS, and JavaScript. This makes them vulnerable to attacks such as Denial of Service (DoS) attacks, Single Point of Failure (SPF), and fraudulent record modification. In this paper, we propose a fully decentralized electronic voting application, SEVA, in which we placed the whole application (code and data) in Ethereum to protect the application from vulnerabilities. Additionally, we propose a new consensus algorithm, Proof of Smart Vote (PoSV) for SEVA, as a viable energy-saving alternative to the energy-intensive Proof of Work (PoW). We implemented and evaluated SEVA with PoSV and compared it with a partially decentralized model of the application.

security vulnerabilities have become significant concerns due to growing demand of Internet of Things (IoT) not only for home automation systems, but also for various industrial applications. Central security technologies are vulnerable to single-point failure that could reduce attack handling technology efficiency. distributed security frameworks are used in resource-constrained heterogeneous IoT networks. Conventional security strategies are insufficient to protect the distributed and dynamic existence of IoT networks. Conversely, Software Define Network (SDN) and Blockchain are two emerging techniques expected to solve heterogeneous IoT network security. This analysis work therefore mainly seeks to examine IoT network features, security specifications, and challenges. Thereafter, well-known threats or attacks are analyzed in IoT. SDN and blockchain-based countermeasures are addressed for IoT network security with a case study. Finally, to enhance security and privacy, numerous open issues are discussed.

With the consistent evolution of distributed networks and cloud computing, the communication process of existing Internet architecture are not at par to offer comprehensive security;thereby fails to cater up the dynamic web security demands of online users. This leads to the evolution of Future Internet Architecture (FIA) that claims of enhanced security system. However, a closer look into both existing web security and security of existing FIA projects shows that there are enough security loopholes in both that demands a novel security solution. Therefore, this paper contributes to investigate the effectiveness of existing web security approaches as well as security approaches of FIA in order to explore the open research issues. The finding of the study shows that there is a significant research gap that demands extreme improvement of existing web security in order to fit for secure communication in FIA.

modern home networks constitute a diverse ecosystem of devices and services, whose management is mostly handled by means of specific service or device provider mechanisms, with only a minority of customers possessing the technical skills required to deal with such tasks. This means that, when it comes to security, most users often exclusively rely on endpoint protection mechanisms (such as anti-virus) to handle their basic needs. This is mostly due to a basic assumption that considers the home LAN to be a safe environment, with most threats coming from the outside a premise that underlies most of the research about the subject. However, this perspective predates the widespread adoption of mobile appliances, smart devices and related services, some of which may be abused and/or compromised to spy and exfiltrate sensitive information from their owners. Overall, one cannot consider the home LAN to be a safe environment anymore, as potential vulnerabilities and information leaks may come from within. This paper addresses the initial phase of the development plan for a security appliance for Home LANs, capable of providing seamless protection for the ever-growing ecosystem of devices and services which are common on such networks, while also addressing the specific requirements imposed by multi-tenancy and cohabitation with third-party services. By monitoring and controlling network traffic flows on a per-device basis, we intend to make it possible to characterize typical traffic profiles for each type of device, to detect anomalies and/or information leaking events. Eventually, this capability may be leveraged to provide to control device-to-device communications in order to block unwanted interactions between equipment and external sites. By moving beyond the last mile and into the customers' doorsteps, the proposed solution intends to provide comprehensive and contextual security monitoring on a per-user basis, embedded at the residential gateway or eventually resorti

Current technology driven world is moving forward with massive implementation of smart objects. These smart objects or Internet of Things (IoT) nodes are involved in sensing of real time critical data from surroundings. Though these IoT nodes are involved in very specific task but their existence is very important for the complete system. Usually, in an IoT architecture, several heterogeneous nodes connect with a nearest gateway. The gateway itself connects with the world via Internet. IoT nodes need to flexible about connectivity as those may need to leave and join any gateway based on context (time, location etc.). To achieve flexibility, IoT components need a trust relationship between each other. In this paper, we have proposed a mechanism for integrating distributed trust management in IoT by using edge computing technology, considering the scalability and heterogeneous capability of IoT devices.
