Abstract
- The coexistence of heterogeneous sub-networks in 6G poses new security and trust concerns and thus calls for a perimeterless-security model. Blockchain radio access network (B-RAN) provides a trust-building approach via repeated interactions rather than relying on pre-established trust or central authentication. Such a trust-building process naturally supports dynamic trusted services across various service providers (SP) without the need for perimeter-based authentications; however, it remains vulnerable to environmental and system unreliability such as wireless channel uncertainty. In this study, we investigate channel unreliability in the trust-building framework based on repeated interactions for secure wireless services. We derive specific requirements for achieving cooperation between SP and client via a repeated game model and illustrate the implications of channel unreliability on sustaining trusted access services. We consider the framework optimization to guarantee SP-client cooperation, given a worst-case channel condition. Furthermore, we introduce the concept of cooperation region to represent the robustness of the trust-building process and explore the maximum cooperation area to enhance service resilience. Finally, we present simulations to demonstrate the system performance over fading channels and verify our results.
