Secure Spectrum and Resource Sharing for 5G Networks using a Blockchain-based Decentralized Trusted Computing Platform
This addresses security risks for 5G network operators and users, but it appears incremental as it builds on existing blockchain and trusted computing concepts for a specific domain.
The paper tackles the security vulnerabilities in 5G networks' Dynamic Spectrum Sharing by proposing a Blockchain-based Decentralized Trusted Computing Platform to protect spectrum resources against cyberattacks in real-time, enabling secure sharing and data exchange.
The 5G network would fuel next-gen, bandwidth-heavy technologies such as automation, IoT, and AI on the factory floor. It will improve efficiency by powering AR overlays in workflows, as well as ensure safer practices and reduce the number of defects through predictive analytics and real-time detection of damage. The Dynamic Spectrum Sharing (DSS) in 5G networks will permit 5G NR and 4G LTE to coexist and will provide cost-effective and efficient solutions that enable a smooth transition from 4G to 5G. However, this increases the attack surface in the 5G networks. To the best of our knowledge, none of the current works introduces a real-time secure spectrum-sharing mechanism for 5G networks to defend spectrum resources and applications. This paper aims to propose a Blockchain-based Decentralized Trusted Computing Platform (BTCP) to self-protect large-scale 5G spectrum resources against cyberattacks in a timely, dynamic, and accurate way. Furthermore, the platform provides a decentralized, trusted, and non-repudiating platform to enable secure spectrum sharing and data exchange between the 5G spectrum resources
