We present a new collusion attack to a kind of quantum secret sharing schemes with entangled states. Using this attack, an unauthorized set of agents can gain access to the shared secret without the others' cooperation. Furthermore, we establish a general model for this kind of quantum secret sharing schemes and then give some necessary conditions to design a secure quantum secret sharing scheme under this model.
我们提出了一种新的纠缠态量子秘密共享方案的合谋攻击。利用这种攻击，一组未经授权的代理可以在没有其他人合作的情况下访问共享秘密。此外，我们为这种量子秘密共享方案建立了一个通用模型，并给出了在此模型下设计安全量子秘密共享方案的一些必要条件。
