The characteristics of the 5G use cases are quite different from any previous generation network, which implies that the 5G trust model must be carefully analysed and defined. The trust model used in networks up to and including 4G has been relatively static over the last 20 years, involving actors such as the user/subscriber and two network operators (home and serving). However, we note that even in this seemingly simple case, the actors and trust relationships are complex and the complete trust model for 4G has never been defined.
Facilitating trust in the dynamic 5G environment
A 5G trust model is required to assist in the design and operation of 5G networks. The security enablers and architecture being developed in the 5G-ENSURE project need to enable and facilitate trust in the dynamic 5G environment, taking into account human and machine factors. This document takes a first step towards defining the actors and business models for 5G and the trust and liability model between these actors, supporting the identified business use cases.
5G-ENSURE Trust Model for 5G networks
The 5G-ENSURE Trust Model (draft) takes the first steps towards such a trust model. It defines related terminology as trust modelling requires precise and commonly understood terms of reference. The document then goes on to review the state of the art in trust modelling, from both a human and machine perspective. The analysis focuses on human trust factors, which are essential components of 5G network scenarios, reviewing also what the options are and the indicators for trustworthiness of other entities, whether they are humans or machines. Finally, the document looks at trust and trustworthiness by design techniques which we recommend for use both during the design of 5G and when changing the design of a 5G deployment by adding or removing elements.
