Proceedings ArticleDOI
On end-to-end approach for slice isolation in 5G networks. Fundamental challenges
Zbigniew Kotulski,Tomasz Wojciech Nowak,Mariusz Sepczuk,Marcin Alan Tunia,Rafal Artych,Krzysztof Bocianiak,Tomasz Osko,Jean-Philippe Wary +7 more
TL;DR: An outline of recent trends in slice isolation and a set of challenges are proposed, which (if properly addressed) could be a step to E2E user's security based on slices isolation.
Journal ArticleDOI
Towards constructive approach to end-to-end slice isolation in 5G networks
Zbigniew Kotulski,Tomasz Wojciech Nowak,Mariusz Sepczuk,Marcin Alan Tunia,Rafal Artych,Krzysztof Bocianiak,Tomasz Osko,Jean-Philippe Wary +7 more
TL;DR: An outline of recent trends in slice isolation and a set of challenges are presented and short outlines of two of the main secure isolation challenges are given: a proper definition of isolation parameters and designing suitable MANO system.
Journal ArticleDOI
5G networks: Types of isolation and their parameters in RAN and CN slices
TL;DR: The approach that makes it possible to establish the common level of isolation for an E2E slice in the 5G network is presented and numerical examples of calculating an isolation level for simple network slices are given.
Journal ArticleDOI
Verticals in 5G MEC-Use Cases and Security Challenges
Tomasz Wojciech Nowak,Mariusz Sepczuk,Zbigniew Kotulski,Wojciech Niewolski,Rafal Artych,Krzysztof Bocianiak,Tomasz Osko,Jean-Philippe Wary +7 more
TL;DR: In this paper, the authors study how the application of the MEC technology affects the functioning of 5G MEC-based services and identify the most sensitive cases to focus on their protection against network attacks in the first place.
Proceedings ArticleDOI
Graph-Based Quantitative Description of Networks' Slices Isolation
TL;DR: A Graph-based model of the sliced network, which has a layered structure, where the appropriate network elements have their own isolation level, and suitable traits are specified and the isolation level in each layer is calculated.
