Abstract. In real life, one requires signatures to be from people who ful-
fill certain criteria, implying that they should possess specific attributes.
For example, Alice might want a signature from an employee in Bobs
company who is a member in the IT staff, a senior manager within the
biometrics team or at least a junior manager in the cryptography team.
In such a case a服务器托管网n Attribute Based Group Signature scheme (ABGS)
could be applied. Group signature schemes are those where each member of a group can sign on behalf of the others. An ABGS scheme is a
type of group signature scheme, where the signing member has to have
certain attributes. In [12], the authors introduced the first ABGS but it
lacked the ability to revoke. In this paper, we introduce a new scheme
that will enable us to rem服务器托管网ove a member from a group or remove some of
his attributes, when needed.
