摘要
分析了以Smolin束缚纠缠态作为通道量子态的量子秘密共享方案的安全性。给出了一个简单的来自通信方内部的截获重发攻击策略,这个攻击策略是依赖比对单量子比特测量结果的窃听检测程序所不能检测出来的。结果表明,仅以束缚纠缠Smolin态作为通道量子态的量子秘密共享方案对于来自内部的窃听攻击不是无条件的。
Abstract
We analyze the security of quantum secret sharing (QSS) with bound entangled Smolin states as the channel quantum state. An intercept-resend strategy of the inner legal communicators is proposed to attack the security without being detected by the checking procedure compared with the results of single-qubit measurement. It is concladed that QQS only with Smolin bound entangled states as the channel quantum state is not unconditionally secure.
