Trusted and secured D2D-aided communications in 5G networks

Abstract

The design of the forthcoming fifth generation (5G) system shall meet the severe requirement of managing an always increasing amount of traffic generated by both humans and machines, while guaranteeing data security. Among the enabling technologies that will turn 5G into a reality, Device-to-Device (D2D) and Multicasting will certainly play a key role because of their capability to largely improve network resources utilization and to address emerging use cases requiring the delivery of the same content to a large number of devices. D2D communications can help to improve traditional point-to-multipoint transmissions by reducing the multicast coverage area and exploiting properly selected relay nodes as data forwarders towards users with worse channel conditions. However, security issues are even more challenging for D2D connections, as data exchange happens directly between nodes in proximity. To enhance performance and security of delivered traffic in 5G-oriented networks, in this paper we design SeT-D2D (Secure and Trust D2D), according to which trustworthiness inferred from both direct interactions and social-awareness parameters is exploited to properly select relay nodes. Main contributions of our research consist in the introduction of a model for the assessment of network nodes' trustworthiness and the implementation of security mechanisms to protect the data transmitted in D2D communications and the privacy of the involved users. The conducted simulation campaign testifies to the ability of the proposed solution to effectively select relay nodes, which leads to an improved network performance.

Lightweight Multifactor Authentication Scheme for NextGen Cellular Networks

“…shows, D 1 has jurisdiction to take the encryption of message Msg using the shared private key. Thus D 1 has jurisdiction over message Msg and vice versa, D 2 also has jurisdiction to use a shared private key and thus D 2 has jurisdiction over message Msg also shown in Equation(10).…”

“…However, typical D2D communication in LTE-A/5G, when allowed to work as intelligent forwarding agent relays, consequently, exposed the communication to several security vulnerabilities and breaches, for instance, quantum attacks, 51% attacks [3], man in the middle (MITM) attack, masquerading attack, denial of service (DoS) attack, rouge relay attack and privacy issues in current 5G/6G cellular networks. Several security schemes have been proposed for D2D communication security which includes River Shamir Adleman (RSA) [4], Diffie Hellman (DH) [5], Elliptic Curve Cryptography (ECC) [6]- [8] , Elliptic Curve Cryptography with Diffie Hellman (ECDH) [9], [10] are few combinations that have been used. These security challenges are more crucial and harder to mitigate because of the resourceconstrained nature of cellular devices.…”

“…While it has been demonstrated that sidelink communications can enhance point-to-multipoint transmissions through efficient relay selection, direct D2D connections present even greater security challenges since data exchange occurs directly between nodes in close proximity. In [127], a to effectively deliver trustworthy multicast/broadcast traffic in 5G-oriented networks is introduced to address this issue. In the same vein, a protocol for effectively managing multicast services with a particular emphasis on security in a 5Goriented IoT environment is proposed in [128].…”
