由于量子器件价格昂贵,采用集体窃听检查的量子秘密共享协议比采用逐步检测的协议更有效,更容易实现。在最近的一篇论文(Lin et al.在Opt. Commun. 282:4455,2009),提出了一种具有集体窃听校验的量子秘密共享协议。然而,高某找到了林某等人的四方协议。是不安全的意义上说,两个不诚实的代理人可能会合作窃听一半的爱丽丝的秘密,而不会引入任何错误(高在Opt. 283:2997,2010)。我们指出,高的攻击策略存在严重的错误,两名特工只能得到爱丽丝秘密的八分之一,而不是一半。本文研究了纠缠交换的性质,改进了Gao的窃听策略,使得两个不诚实的代理人可以得到Alice的全部秘密。我们还改进了Lin et al.'的量子秘密共享协议来对抗这种攻击。
Because quantum devices are expensive, quantum secret sharing protocols with collective eavesdropping-check are more efficient and easier to realize than protocols employing step-by-step detection. In a recent paper (Lin et al. in Opt. Commun. 282:4455, 2009), put forward a quantum secret sharing protocol with collective eavesdropping-check. However, Gao found the four-party protocol of Lin et al. is insecure in the sense that two dishonest agents may collaborate to eavesdrop half of Alice’s secret without introducing any error (Gao in Opt. Commun. 283:2997, 2010). We point that there is a grievous mistake in Gao’s attack strategy and the two agents can only get one eighth of, not half of, Alice’s secret. In this paper, we study the properties of entanglement swapping and improve Gao’s eavesdropping strategy so that two dishonest agents can get all of Alice’s secret. Also we improve Lin et al.’s quantum secret sharing protocol against such attack.
