基于可重用GHZ态作为安全载体的安全量子秘密共享

Secure Quantum Secret Sharing Based on Reusable GHZ States as Secure Carriers

Jie Song, Shou Zhang

摘要:

我们证明了当合法用户使用安全载体在协议中重复地对经典信息进行编码和解码时,潜在的窃听者可以窃听整个秘密信息[Bagherinezhad S和Karimipour V 2003 Phys. Rev. A \textbf{67} 044302中提出]。在此基础上,我们提出了一个改进的量子秘密共享协议,该协议以Greenberger-Horne-Zeilinger态为安全载体。我们的协议可以抵抗夏娃的攻击

英文摘要:

We show a potential eavesdropper can eavesdrop whole secret information when the legitimate users use secure carrier to encode and decode classical information repeatedly in the protocol [proposed in Bagherinezhad S and Karimipour V 2003 Phys. Rev. A \textbf{67} 044302]. Then we present a revised quantum secret sharing protocol by using Greenberger-Horne-Zeilinger state as secure carrier. Our protocol can resist Eve's attack.
