This activity constitutes to be the follow-up activity of the topic Second Factor Authentication - Distributed Vetting (see: https://wiki.geant.org/x/zLAuBw) of the previous Incubator cycle. It investigates analogously to the preceding cycle how identity vetting and token registration can be scaled for second-factor authentication scenarios where participants are distributed over EU and beyond and thus takes into account the report which was delivered as part of the first Incubator cycle. As part of this activity a specific flow - based on a community-based approach - will be investigated. It takes into account the concept of the Web of Trust which is also used in (Open)PGP to establish a binding between a key and its owner. While this mechanism typically does not work well in broad user groups, it is very well suited to distribute trust between small groups where a pre-existing trust fabric is already in place, as we typically have in research communities. What seems to be missing is a means to make this trust network auditable and transparent. In order to make the trust network transparent, this activity seeks to identify/develop tools to support this flow. |
