Comment on "Cryptanalysis and improvement of multiparty quantum secret sharing schemes"

Abstract

We show that, using Wang et al. attack [T.-y. Wang, Q.-y. Wen, F. Gao, S. Lin, F.-c. Zhu, Phys. Lett. A 373 (2008) 65], the first agent and the last agent cannot eavesdrop all the secret messages in Zhang et al. QSSCM scheme [Z.-j. Zhang, G. Gao, X. Wang, L.-f Han, S.-h. Shi, Opt. Commun. 269 (2007) 418]. In some sense, Wang et al. attack is unsuccessful for Zhang et al. QSSCM scheme.

A note on Wanget al's attack on Zhanget al's multiparty quantum secret sharing

Gan Gao

Recently, Wang et al (2008 Phys. Lett. A 373 65) proposed an attack on Zhang et al's (2007 Opt. Commun. 269 418) multiparty quantum secret sharing scheme, in which the first and the last agent are reported to be able to cooperatively eavesdrop on all the secret messages without being detected. In this paper, we show that in Wang et al's attack, on average no more than half the secret messages can be eavesdropped.

In this paper, we show that the attack strategy [A. Yin and F. Fu, Mod. Phys. Lett. B 30 (2016) 1650415] fails, that is, the last agent and other agents cannot get the sender’s secret keys without being detected by using the attack strategy.

Comment on “Multiparty quantum secret sharing of classical messages based on entanglement swapping”

Song Lin, Fei Gao, Fen-Zhuo Guo +2 more

In a recent paper [Z. J. Zhang and Z. X. Man, Phys. Rev. A 72, 022303 (2005)], a multiparty quantum secret sharing protocol based on entanglement swapping was presented. However, as we show, this protocol is insecure in the sense that an unauthorized agent group can recover the secret from the dealer. Hence we propose an improved version of this protocol which can stand against this kind of attack.

Reexamining Security of Improved Multiparty Quantum Secret Splitting and Quantum State Sharing

Song Lin

In a recent letter [H.F. Wang, X. Ji, and S. Zhang, Phys. Lett. A 358 (2006) 11], an improvement of the multiparty quantum secret splitting and quantum state sharing protocol [F.G. Deng, et al., Phys. Lett. A 354 (2006) 190.] was presented. We study the security of the improved protocol and find that two or more dishonest participants may recover the secret from the dealer. Hence we further modify the improved protocol, which make it stand against this kind of attack.

Cryptanalysis and Improvement of a Quantum Secret Sharing Protocol between Multiparty and Multiparty with Single Photons and Unitary Transformations

Zhen-Chao Zhu, Yuqing Zhang

In a recent paper [ Chin. Phys. Lett 25(2008)1187 ], a quantum secret sharing scheme between multiparty and multiparty was presented. We show that the protocol is not secure because the last member in Alice's group can illegally obtain most secret messages without introducing any error. Finally, a possible way to avoid the security flaw is suggested.

Comment on “Quantum secret sharing between multiparty and multiparty without entanglement”

Chuan-Ming Li, Chi-Chao Chang, Tzonelih Hwang

Recently, Yan and Gao [Phys. Rev. A 72, 012304 (2005)] presented a quantum secret sharing protocol which allows a secret message to be shared between two groups of parties ($m$ parties in group 1 and $n$ parties in group 2). Their protocol is claimed to be secure that, except with the cooperation of the entire group 1 or group 2, no subgroup of either group 1 or group 2 can extract the secret message. However, this study points out that the $m\text{th}$ party (the last party to process the quantum state) of group 1 can maliciously replace the secret message with an arbitrary message without the detection of the other parties.
