A whole suite of innovative technologies and architectures have emerged in response to the rapid growth of wireless traffic. This paper studies an integrated network design that boosts system capacity through cooperation between wireless access points (APs) and a satellite for enhancing the network's spectral efficiency. As for our analytical contributions, upon coherently combing the signals received by the central processing unit (CPU) from the users through the space and terrestrial links, we first mathematically derive an achievable throughput expression for the uplink (UL) data transmission over spatially correlated Rician channels. Our generic achievable throughput expression is applicable for arbitrary received signal detection techniques employed at the APs and the satellite under realistic imperfect channel estimates. A closed-form expression is then obtained for the ergodic UL data throughput, when maximum ratio combining is utilized for detecting the desired signals. As for our resource allocation contributions, we formulate the max-min fairness and total transmit power optimization problems relying on the channel statistics for performing power allocation. The solution of each optimization problem is derived in form of a lowcomplexity iterative design, in which each data power variable is updated relying on a closed-form expression. Our integrated hybrid network concept allows users to be served that may not otherwise be accommodated due to the excessive data demands. The algorithms proposed allow us to address the congestion issues appearing when at least one user is served at a rate below his/her target. The mathematical analysis is also illustrated with the aid of our numerical results that show the added benefits of considering the space links in terms of improving the ergodic data throughput. Furthermore, the proposed algorithms smoothly circumvent any potential congestion, especially in face of high rate requirements and weak channel conditions.

“…It requires authentication of the user terminal at the application layer. The authentication can be based on credentials such as a token, certificate, or user ID/password between the user terminal and the application [3]. 3GPP proposed the authentication and key management for application (AKMA) scheme through TS 33.535 [4] and TS 38.535 [17].…”

<p>5G advanced technology has introduced innovative multimedia services, thus propelling the rise of the mobile multimedia market. While the ubiquity of mobile multimedia services has boosted customer convenience, it has also unlocked the way to possible security concerns that potentially damage users’ privacy and service providers’ properties. Several standards and researches have been proposed to counter these threats, notably those concentrating on authentication between users and service applications. Unfortunately, these studies are limited to address a new challenge, secure handover among distributed application functions in 5G Multi-access Edge Cloud (MEC) environments. Motivated by this, we present a handover authentication protocol with push-key and pull-key optimization options in 5G mobile multimedia application services. The proposed protocol provides mutual authentication, secure key exchange, confidentiality, and integrity. Furthermore, it also supports perfect forward secrecy, optimal handover, and anonymity, which were not previously considered in prior studies. While formal verification through BAN Logic and Scyther proved that the protocol is secure against attacks that violate the supported security requirements, comparative analysis of the proposed protocol against existing studies demonstrates that the protocol is simultaneously efficient.</p> <p> </p>

AKMA (Application Authentication and Key Management) is a technology that 3GPP (3rd Generation Partnership Project) provides security capabilities to 5G (5th generation wireless systems) as a third party. At present, 3GPP has finalized the publication of AKMA specifications in Release 16 and is developing AKMA phase 2 in Release 18. At the current stage, it is recommended to conduct enhanced research on AKMA to solve some security problems of AKMA. This paper first briefly describes and analyzes the principles and technological development process of two mainstream application authentication technologies GBA (Generic Bootstrapping Architecture) and AKMA, and analyzes the advantages and limitations of these two technologies. Secondly, we also analyze the signaling loss caused by the AKMA process conducted independently by different application servers in the same trust domain, and the security risk caused by the long-term use of the same application key by AKMA users. Finally, this paper proposes solutions to AKMA performance and security problems from the perspective of security, universality, and performance impact.
