“…[3,7,10,11,14] from the following five aspects: quantum resource, vulnerability to the verifier forgery attack, message unblinding process, unlinkability and the total efficiency. Assuming that decoy quantum states used for checking of eavesdropping is not counted, the total efficiency defined by Cabello [21] expresses as…”

“…In general, a blind signature protocol includes three stages as follows [1,2]: (1) Now, some quantum blind signature (QBS) schemes were presented [3][4][5][6][7][8][9][10][11][12][13][14]. In 2009, the first weak blind signature scheme based on EPR pairs was proposed by Wen et al [3]. Based on single photons, Wang and Wen [4] proposed a fair blind signature scheme.…”

Recently, some quantum blind signature protocols have been proposed. However, the previous schemes cannot satisfy the unlinkability requirement. To overcome the drawback of unlinkability in the previous schemes, we propose a new quantum blind signature based on Bell states with the help of an authentic party. In this paper, we provide a method to inject a randomizing factor into a message when it is signed by the signer and then get rid of the blind factor from the blinded signature when it is verified by the verifier. Even when the message owner publishes the message-signature pair, the signer cannot identify the association between the message-signature pair and the blind signature he generated. Therefore, our scheme really realizes unlinkability property. At last, analysis results show that this scheme satisfies the basis security requirements of a weak signature such as no-counterfeiting, no-disavowing, blindness and traceability, and our total efficiency is not less than the previous schemes.

In this paper, we propose a new secure quantum proxy multi-signature scheme using seven-qubit entangled quantum state as quantum channels, which may have applications in e-payment system, e-government, e-business, etc. This scheme is based on controlled quantum teleportation. The scheme uses the physical characteristics of quantum mechanics to guarantee its anonymity, verifiability, traceability, unforgetability and undeniability.

We present a quantum signature scheme using a single qubit rotation operator. In this protocol, the trusted center confirms the quantum signature and thus conforms with other quantum signature schemes. Utilizing the unitary properties of a single qubit rotation operator and Pauli operators, our protocol provides signature security and enhances the efficiency of communication. In addition, our protocol -using only a single qubit measurement -facilitates the ease of implementation and enhances convenience for users. The security of the protocol is analyzed.
