- Abstract
A novel quantum group proxy blind signature scheme based on five-qubit entangled state is proposed. The quantum key distribution, quantum encryption algorithm and some laws of quantum mechanics (such as quantum no-cloning theorem and Heisenberg uncertainty principle) are used to guarantee the unconditional security of this scheme. Analysis result shows that the signature can neither be forged nor disavowed by any malicious attackers and our scheme satisfies all the characteristics of group signature and proxy signature. This protocol can be applied in real life such as E-commerce transaction.
