Research communities have a need to express and potentially share certain trust marks on IdPs and SPs. These trust marks may differ from exiting existing trust marks issued by identity federations, or may be put in to compliment existing ones, in case the federation operator does not support these, like e.g. in the case of SIRTFI. This project tries to implement a technical solution that matches the requirements as described by the SIRTFI community and investigates usability of the solution for research communities and the impact of the solution of Identity federations. It also explores potential other scenarios where a similar methodology could be used, like e.g. REFEDs MFA and in the context of the IdP self assessment tool that was developed in GN42 It does not consider itself with the questions on where and how such a tool would be used in the context of existing trust frameworks. |
