Top Research Papers on Network Security

Starting with the historical evolution of computer and communications networks and their security, the book then arrives at the main definitions of cryptography and network security. Next, the basics of information theory, how to measure information, the information associated with a certain source are also discussed. Source codes are presented, along with the concepts of information transmission, joint information, conditional entropy, mutual information and channel capacity. Computer networks are discussed, including the main protocols and network architectures, and the important TCP/IP prot...

This chapter discusses the chief objectives of securing a network and provides information on information security terminology. The aim of network security is to provide proactive defense methods and mechanisms to protect a network against internal and external threats. The three main objectives in securing a network are to ensure: confidentiality, integrity, and availability. The chapter describes the types of network security and the chief risks related to the logical security of a network. Different kinds of network attacks include reconnaissance attack, password attacks access attacks, net...

The sixth generation (6G) of mobile network will be composed by different nodes, from macro- devices to nano- devices, providing a full connectivity fabric all around us, and physical-layer security (PLS) can act as a first line of defense, providing security even to low-resourced nodes in different environments.

This article spotlighting the security in 5G network slicing highlights threats and recommendations, which are presented in terms of life-cycle security, intra-slice security, and inter-sliceSecurity, and identifies and discusses open security issues related to network slicing.

This paper proposes two schemes to guarantee the secure transmission in UAV-NOMA networks by derive the hovering position for the UAV and the power allocation to meet rate threshold of the secure user while maximizing the sum rate of remaining users.

A blockchain-based secure FL framework to create smart contracts and prevent malicious or unreliable participants from being involved in FL is proposed, which can effectively deter poisoning and membership inference attacks, thereby improving the security of FL in 5G networks.

The emergence of the Mobile Ad Hoc Networking (MANET) technology advocates self-organized wireless interconnection of communication devices that would either extend or operate in concert with the wired networking infrastructure or, possibly, evolve to autonomous networks. In either case, the proliferation of MANET-based applications depends on a multitude of factors, with trustworthiness being one of the primary challenges to be met. Despite the existence of well-known security mechanisms, additional vulnerabilities and features pertinent to this new networking paradigm might render such tradi...

How security and privacy can be destroyed by attacking one of the three technologies and how the three services support each other to realize efficient and achievable security protection is explained.

A 15-user quantum secure direct communication network based on time–energy entanglement and sum-frequency generation is experimentally demonstrated, and any two users can perform QSDC task over 40 kilometers of optical fiber.

Anomaly detection is crucial in various applications, particularly cybersecurity and network intrusion. However, a common challenge across anomaly detection techniques is the scarcity of data that accurately represents abnormal behavior, as such behavior is often detrimental to systems and, consequently, rare. This data limitation hampers the development and evaluation of effective anomaly detection methods. In recent years, Generative Adversarial Networks (GANs) have garnered significant attention in anomaly detection research due to their unique capacity to generate new data. This study cond...
