While attention is often focused on extending exciting applications such as immersive extended reality (XR), digital twin, interacting cobots, and trusted native AI, NGMN firmly believes it is essential to establish the indisputable trustworthiness of the 6G network. Considering this, NGMN has identified several technology trends that will influence the trustworthiness of a 6G network including network AI, open source, virtualisation and containerization, and quantum computing which might bring new security threats. 6G networks must therefore have an inherent trustworthiness design to promote the effectiveness of security protection and enhance the ability of privacy protection, such as trusted computing and blockchain. In the subsequent sections of this publication, we pull all these technology trends together, providing the industry with comprehensive guidance to ensure trustworthiness in the 6G network. By embracing a holistic approach to security and privacy, we can not only enable the realisation of future 6G use cases but also safeguard the interests and trust of end-users. 3 CONTENTS 01 INTRODUCTION ....................................................... 5 05 DESIGN CONSIDERATIONS OF 6G TRUSTWORTHINESS.............................. 15 - 16 5.1 Decentralised trust foundation ....................... 15 02 KEY DRIVERS OF 6G TRUSTWORTHINESS ..................................... 6 - 7 5.2 Dynamic trust model................................................15 5.3 Intelligent collaboration........................................ 15 2.1 Societal demands ....................................................... 6 5.4 Security as a service ............................................... 16 2.2 Network evolution demands................................ 6 5.5 Trust and risk assessment .................................. 16 2.3 Service driven demands ......................................... 6 2.4 Security technologies driven demands ......... 7 03 USE CASES ANALYSIS .............................. 8 - 11 3.1 Enhanced human communication.................... 8 06 07 CONCLUSION AND ROADMAP............ 17 ABBREVIATIONS .................................................. 18 3.2 Enhanced machine communication............8 - 9 3.3 Enabling services ............................................... 9 - 10 3.4 Network evolution ................................................... 11 04 4 6G TRUSTWORTHINESS REQUIREMENTS ........................................ 12 - 14 08 09 ACKNOWLEDGEMENTS ............................... 19 REFERENCES ............................................................. 20 01 INTRODUCTION The mobile network is a critical element of both societal and industrial development. 6G telecommunications system developments have already begun in the industry with NGMN having identified that 6G needs to be driven by societal goals, market expectations and operational necessities. 6G will enable and extend both current 5G use cases as well as 6G envisioned uses cases [2]. 6G mobile network infrastructure must support curren
