| Abstract(in English) | Group signature scheme is the digital signature scheme enhancing the privacy of the user, and efficient pairing-based schemes have been proposed. Recently, some attribute-based group signature schemes are proposed, where the signer's attributes can be verified. The attribute-group signature allows us to construct more complex groups, because it can prove the logical relation of attributes such as 'AND' and 'OR'. However, the previouse schemes, the number of pairings and exponentiations in signing and verification depends on the number of attributes. In this paper, we propose an efficient attribute-base group signature scheme, where the computational complexity doesn't depend on the number of attributes. |
