“…Blockchain networks have been widely adapted for cybersecurity of the Internet of Things (IoT) [6], Internet of Vehicles (IoV) [7] and Edge-Fog computing [8]. The companies and groups such as IOTA 1 , Dfinity 2 , Ethereum 3 , Lightening Group 4 and NEO 5 are working working on blockchain 3.0 projects [9]. There are two types of BCNs, namely permissionless and permissioned.…”

“…allocated compute or storage resources), should be identifiable by those managing the services (e.g., MNOs) and those requesting the service (e.g., vertical SPs). Transparency should also be established between multiple entities to prevent some entities (e.g., CSPs or MNO) being dishonest and blaming others to avoid penalties when network service delivery failures occur (e.g., due to the malfunction of some network devices [4]).…”

Blockchain technologies are gradually being deployed in a variety of industries, including telecommunications. In this paper, due to the strict governance of telecommunication infrastructure, we propose a permissioned distributed ledger (PDL)-based blockchain supported architecture for a network management and orchestration platform. The work focuses on creating a trusted environment for both Cloud Service Providers (CSPs) and Mobile Network Operators (MNOs) for managing the lifecycle of network services (e.g., instantiation, scaling, termination, etc.) in a multi-cloud environment. We also validate our proposed approach with an experimental scenario using the Quorum blockchain network (BCN) to measure various performance metrics (e.g., number of transactions and blocks, time to write, and transactions per second) of different service orchestrator (SO)-related instantiation metrics. Our evaluation results show that the values for the service instantiation time and the corresponding BCN metrics can be completely different, suggesting that some logs arrive very quickly and generate a high transaction load, while others take longer and generate a low number of transactions. As a solution, at the end of the paper, we also provide some recommendations for appropriate optimizations during transfer of SO-related logs to BCNs and some observed challenges.

“…From an accountability point of view, if a device malfunctions, network operators should be able to identify precisely the device which failed to meet its quality standards. Transparency, on the other hand, is essential because some dishonest vendors may try to hide their errors and blame others, to save themselves from having to pay a penalty [5].…”

Infrastructure sharing is a widely discussed and implemented approach and is successfully adopted in telecommunications networks today. In practice, it is implemented through prior negotiated Service Level Agreements (SLAs) between the parties involved. However, it is recognised that these agreements are difficult to negotiate, monitor and enforce. For future 6G networks, resource and infrastructure sharing is expected to play an even greater role. It will be a crucial technique for reducing overall infrastructure costs and increasing operational efficiencies for operators. More efficient SLA mechanisms are thus crucial to the success of future networks.In this work, we present "BEAT", an automated, transparent and accountable end-to-end architecture for network sharing based on blockchain and smart contracts. This work focuses on a particular type of blockchain, Permissioned Distributed Ledger (PDL), due to its permissioned nature allowing for industry-compliant SLAs with stringent governance. Our architecture can be implemented with minimal hardware changes and with minimal overheads.

The 5G is all set to create a paradigm shift in the telecommunication network architecture by introducing a millimeter‐wave‐based customizable radio network and a redesigned cloud‐native core network to offer high‐speed, low‐latency mobile broadband anytime anywhere. The key enabling technologies of the 5G are massive MIMO, beamforming, Software‐Defined Networking (SDN), Network Functions Virtualization (NFV), and Mobile Edge Computing (MEC). However, the network agility, connection to billions of smart things, and blind adoption of machine learning models and open‐source software in the networked systems bring in a unique set of security threats and privacy concerns to the network and its stakeholders. This article provides a comprehensive analysis of the evolving security threat landscape of 5G, recommended security measures, current state‐of‐the‐art solutions, and open research areas.
