Abstract

Recently, a multiparty semiquantum secret sharing scheme based on rearranging orders of qubits was proposed by Gao et al. [Mod. Phys. Lett. B 30 (2016) 1650130]. In this paper, we show that in their scheme the last agent and other agents can illegally get the sender’s secret keys without being detected. Furthermore, an improved scheme is proposed to resist such attack.

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.

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.

Eavesdropping on the multiparty semi-quantum secret sharing protocol based on single qubit sequence and permutation

Gan Gao, Xueying Cui, Ming Fang

The paper [Xin et al., Mod. Phys. Lett. A 39, 2450084 (2024)] proposed a multiparty semi-quantum secret sharing protocol based on the single qubit sequence and the permutations of the qubit locations. We study the security of the proposed protocol and point out that there exists a security loophole in it, that is, the first and last agents can collude to obtain Tom’s secret without the help of the other agents.

Cryptanalysis and improvement of the novel semi-quantum secret sharing scheme based on Bell states

Bingren Chen, Wei Yang, Liusheng Huang

A recent paper proposed a semi-quantum secret sharing (SQSS) scheme based on Bell states [A. Yin et al., Mod. Phys. Lett. B. https://doi.org/10.1142/S0217984917501500 ]. This protocol was presumed that only the sender has the quantum power and all participants perform classical operations. However, we find this protocol is not that secure as it is expected. We can utilize the intercept-resend method to attack this scheme. Then, we give an improvement strategy based on semi-quantum key distribution, which ensures that the new scheme resists the attack we have proposed.

Cryptanalysis and improvement of the novel semi-quantum secret sharing scheme using entangled states

Qijian He, Wei Yang, Bingren Chen +1 more

A semi-quantum secret sharing scheme using entangled states was proposed in a recent paper [Mod. Phys. Lett. B 32 (2018) 1850256. https://doi.org/10.1142/S0217984918502561 ]. We find a loophole of this scheme. Based on the intercept-resend attack, we propose a deterministic attack strategy and a probabilistic attack strategy. The malicious participant can escape the detection and obtains the secret. We also suggest two improvements to help increase the security of the original scheme.

Multiparty semiquantum secret sharing based on rearranging orders of qubits

Gan Gao, Yue Wang, Dong Wang

Based on the assumption of a perfect qubit, Boyer et al. proposed a novel semiquantum key distribution protocol [Phys. Rev. Lett. 99 (2007) 140501], in which quantum Alice shares a secret key with classical Bob. In this paper, we use Bell states to propose a multiparty semiquantum secret sharing (MSQSS) protocol, in which only the boss is quantum and all agents are classical. Classical agents are restricted to performing measurements in a computational basis and rearranging orders of qubits. Unless all classical agents collaborate, no subset of them can obtain the secret of the quantum boss. Also, we show that this proposed protocol is secure against eavesdropping.
