Abstract: | Alice needs a document signed by an employee in Bob's company. That employee should be part of the IT staff and is at least a junior manager in the cryptography team or a senior manager in the biometrics team. In such a scenario we need an Attribute Based Group Signature Scheme (ABGS). In this paper we define the first ABGS scheme where verifying includes authenticating a person that belongs to a certain group and owns particular attributes. We define two security notions adopted from group signature which are: traceability and anonymity. We prove our scheme to be secure under those two notions. |
