一种新型的量子秘密共享方案

在实际应用中,秘密共享网络的发展一般会有成员扩展的需求。但是,现有的量子秘密共享方案在设计时很少考虑网络的可扩展性。利用相对简单经济的量子资源,设计了一种可扩展的量子秘密共享方案。它在成员扩展阶段无需代理协助,因而有助于避免秘密共享的内部欺骗。最后从三个方面讨论了本方案的安全性。

A new quantum secret sharing scheme

In the practical applications, member expansion is a usual demand during the development of a secret sharing network. However, there are few consideration on network expansibility in the existing quantum secret sharing schemes.We proposed an expansible quantum secret sharing scheme with relatively simple and economical quantum resources. Its trait, no requirement of any agents assistant during the process of member expansion, can help to prevent potential menaces of insider cheating. We also gave a discussion on the security of this scheme from three aspects.
