Abstract
Digital signatures are widely used in electronic communications, for example in electronic commerce and e-mail. But classical digital signature scheme only offer security relying on computational assumptions. In contrast, quantum digital signatures provide security based on fundamental principles of quantum physics. Quantum group signatures provide anonymity for signatory, quantum blind signatures provide confidentiality for signed messages. In this paper we demonstrate a quantum group blind signature scheme which have the properties both of group signatures and blind signatures. Besides, the security of our scheme is guaranteed by the quantum mechanics, so without any computational assumption. the group property and blind property of our scheme profits from the properties of the measurement-based quantum computation (MBQC). Our quantum group blind signature scheme can be widely used in e-voting system, e-cash, e-commerce, etc.
