As two major communication technologies, the Internet and wireless, are maturing rapidly to dominate our civilised life, the authors urgently need to re-establish users' confidence to harvest new potential applications of large-scale distributed systems. Service agents and distributed multi-agent systems (MASs) have shown the potential to help with this move as the lack of trust caused by heavily compromised security issues and concerns coupled with the out-of-date solutions are hindering the progress. The authors therefore seek new remedies to ensure that the continuity in developing new economies is maintained through building new solutions to address today's techno-economical problems. Following a scan of the literature the authors discuss the state-of-the-art progress followed by some observations and remarks for the researchers in the field. Here the authors recognise the need for new 'distributed security' solutions, as an overlay service, to rejuvenate and exploit the distributed artificial intelligence (AI) techniques for secure MAS as a natural solution to pave the way to enable a long awaited application paradigm of the near future.

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

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.

INTERNATIONAL JOURNAL OF NETWORKED AND distributed COMPUTING 2019年第2期7卷 68-84页

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.

Wireless sensor networks (WSNs) have many applications that handle sensitive information such as surveillance, reconnaissance, and target tracking. Therefore, a WSN deployed in a hostile region should be resilient to attacks. The current approach to defending against malicious threats is to develop and deploy a specific defense mechanism for a specific attack. However, the problem with this traditional approach to defending sensor networks is that the solution for the jamming attack does not defend against other attacks (e.g., sybil, selective forwarding, and wormhole attacks). In reality, one cannot know a priori what type of attack an adversary will launch. Also, given the resource constraints of sensor nodes, the current defense mechanisms cannot be simply combined on the node to provide a complete solution. This work addresses the challenges with the traditional approach to securing sensor networks and presents a collaborative framework (the distributed security Framework - DSF) that can defend against all known attacks. The framework is extensible, therefore, as new attacks are discovered they can also be defended against. The DSF leverages existing defense mechanisms created by researchers. These defense mechanisms are distributed in such a way that they can, collectively, provide comprehensive defense to the network. The efficacy of the DSF is determined using simulations for scenarios consisting of multiple stationary and multiple mobile attackers. The simulation results show that though the DSF consumes more energy than single defense schemes, it can significantly enhance the network security even when the network is under multiple types of attacks.

Due to the increasing threat of attacks and malicious activities, the use of firewall technology is an important milestone toward making networks of any complexity and size secure. Unfortunately, the inherent difficulties in designing and managing firewall policies within modern highly distributed, dynamic and heterogeneous environments might greatly limit the effectiveness of firewall security. It is therefore desirable to automate as much as possible the firewall configuration process. Accordingly, this work presents a new more active and scalable firewalling architecture based on dynamic and adaptive policy management facilities, thus enabling the automatic generation of new rules and policies to ensure a timely response in detecting unusual traffic activity as well as identify unknown potential attacks (zero-day). The proposed scheme, with a multi-stage modular structure, can be easily applied to a distributed security environment and does not depend on any specific security solutions or hardware/software packages.

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.

Resource Consumption Analysis of distributed Machine Learning for the security of Future Networks

Procedia Computer Science 2024年 251卷 66-74页

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.

IDENTITY AUTHENTICATION IN HETEROGENEOUS COMPUTING ENVIRONMENTS - A COMPARATIVE-STUDY FOR AN INTEGRATED FRAMEWORK

COMPUTERS & security 1994年第3期13卷 231-253页

Identity authentication systems form the basis of many security mechanisms in many distributed computing environments today. All authentication mechanisms are based on some form of secret sharing coupled with some cryptographic methods. Each implementation is based on a conceptual model for authentication and makes certain assumptions about the network characteristics on which the distributed system is based. This paper presents conceptual models for authentication and their implementations because of their practical importance. The authentication methods are analysed in terms of their diversity, and a framework for interoperability in a heterogeneous environment is proposed.

Wireless sensor networks (WSNs) are being used for many applications ranging from mobile target surveillance to intelligent home networking. Due to the sensitive nature of the data transmitted by these applications, appropriate protection mechanisms are needed to prevent attackers from exploiting the weaknesses of the radio links. In this paper, we propose a novel group key management scheme called DynTunKey (dynamic tunneling and group key management protocol). This paper investigates the use of secure tunnels as a solution to improve the protection of WSNs. We propose a tunneling scheme that conforms to the security requirements of WSNs while having less computational and network overhead. We also propose a solution for a dynamic integration in the secured communication of a newly deployed sensor. A set of experiments has been conducted to assess the performance of the proposed scheme with regard to recent key management protocol and to traditional tunnels built using the IPSec protocol. We found that our protocol considerably reduces the number of transmitted messages as well as the computational load, which makes it suitable for WSNs. We tested the proposed protocol considering two models of mobility of the targets which are respectively the Random Walk model and the Gauss Markov model.

In a local area network (LAN), the availability of all network components is indispensable. To reach this goal it is necessary to secure a LAN against unwanted communication from outside. If there is an unauthorized access which blocks the internal traffic, the security mechanism has to react and must exclude this traffic from the internal network.
