In traditional mobile networks', trust between subscribers and their serving networks is based on a hardware root-of-trust: the SIM. Trust between service and home networks, when different, was based on Trusted Third Parties (TTPs), called Clearing Houses (CHs), which guarantee the trustworthiness of the evidence about service use. The 6G scenario will see the number of subscribers boosted by mass deployment of Internet-of-Everything as well as the improvement of the network performance. At the same time, the performance required to the TTP to manage 6G operator-to-operator (O2O) trustworthy interactions must be aligned to the 6G ecosystem requirements as well. However, supporting scalability in 6G O2O trust is still considered an open challenge. The aim of this paper is to tackle this challenge by presenting a blockchain-based approach for CHs, able to support O2O trustworthy interactions in the 6G scenario.

Abstract
In traditional mobile networks', trust between subscribers and their serving networks is based on a hardware root-of-trust: the SIM. Trust between service and home networks, when different, was based on Trusted Third Parties (TTPs), called Clearing Houses (CHs), which guarantee the trustworthiness of the evidence about service use. The 6G scenario will see the number of subscribers boosted by mass deployment of Internet-of-Everything as well as the improvement of the network performance. At the same time, the performance required to the TTP to manage 6G operator-to-operator (O2O) trustworthy interactions must be aligned to the 6G ecosystem requirements as well. However, supporting scalability in 6G O2O trust is still considered an open challenge. The aim of this paper is to tackle this challenge by presenting a blockchain-based approach for CHs, able to support O2O trustworthy interactions in the 6G scenario. Both home and roaming use cases are considered.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
