Abstract

A quantum proxy group signature scheme is proposed with χ-type entangled states. Our scheme combines the properties of group signature and proxy signature. Moreover, the particles in the χ-type state sequence are used to distribute proxy warrants and quantum keys in the initial phase, and then used for quantum signature. Therefore it increases the utilization rate of quantum resources compared with the general quantum signature scheme. Finally, the unconditional security of our scheme is also analyzed.

DISCUSSION ON QUANTUM PROXY GROUP SIGNATURE SCHEME WITH χ-TYPE ENTANGLED STATE

Hui-Juan Zuo, Su‐Juan Qin, Tingting Song

Recently, Yin et al. (Int. J. Quantum Inform. 10 (2012) 1250041) proposed a quantum proxy group signature scheme with χ-type entangled states. The scheme combines the properties of group signature and proxy signature. The study points out that the semi-honest Trent can give the forged signature under the assumption of this scheme. And, we find that even if the three parties honestly perform the scheme, the signature still cannot be realized with high efficiency.

A quantum proxy group signature scheme based on an entangled five-qubit state

Meiling Wang, Wenping Ma, Lili Wang +1 more

A quantum proxy group signature (QPGS) scheme based on controlled teleportation is presented, by using the entangled five-qubit quantum state functions as quantum channel. The scheme uses the physical characteristics of quantum mechanics to implement delegation, signature and verification. The security of the scheme is guaranteed by the entanglement correlations of the entangled five-qubit state, the secret keys based on the quantum key distribution (QKD) and the one-time pad algorithm, all of which have been proven to be unconditionally secure and the signature anonymity.

A quantum proxy blind signature protocol

Yu Xiaoqiang, Xiaohui Zhao

A proxy blind signature protocol using quantum entanglement state for signature and verification was proposed, while nonorthogonal quantum state encoded proxy warrant message. The quantum key distribution and one-time pad encryption algorithm guaranteed the unconditional security and the message owner's anonymity.

Arbitrated quantum signature scheme based onχ-type entangled states

Hui-Juan Zuo, Wei Huang, Su‐Juan Qin

An arbitrated quantum signature scheme, which is mainly applied in electronic-payment systems, is proposed and investigated. The χ -type entangled states are used for quantum key distribution and quantum signature in this protocol. Compared with previous quantum signature schemes which also utilize χ -type entangled states, the proposed scheme provides higher efficiency. Finally, we also analyze its security under various kinds of attacks.
