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