| Abstract | Abstract. We introduce the notion of Cross-Unlinkability for group signature schemes. Considering groups organized in a tree structure, where belonging to the parent group is required to join a new group, Cross-Unlinkability enables a cascade revocation process that takes into account the underlying tree structure, while ensuring anonymity for nonrevoked users, in particular, towards the managers of the other groups. We show how to achieve Cross-Unlinkability using the Verifier-Local Revocation group signature scheme of Bringer and Patey at Secrypt 2012, by exploiting its property of Backward Unlinkability. |
