摘要: 秘密共享是指将一个秘密按适当的方式进行隐藏或拆分,只有若干个参与者一同协作才能恢复该秘密,该技术在云计算领域中能够确保信息安全和数据保密。提出了一种不使用纠缠态的量子秘密共享协议,通过使用量子密码算法确保系统的安全性。相比其他的秘密共享协议,该协议具有以下优点:与传统的基于数论的秘密共享协议相比,本协议由于使用量子通信的技术,从而能够有效抵抗Shor算法攻击;相比其他的量子秘密共享协议,由于本协议没有使用量子纠缠态,在技术程度上更容易实现;如果存在攻击者或恶意的参与者,该协议能够在秘密恢复过程中迅速发现,避免恢复错误的秘密。

Abstract: Secret sharing refers to the method for distributing a secret amongst a group of participants,and the secret can be reconstructed only when a sufficient number of shares are combined together,it can ensure the information secure and data protection in cloud computing.This paper proposes a new quantum secret sharing protocol without particle entangled state,which can guarantee unconditional security by using quantum one-time pads,quantum key cryptosystem and the technique of comparing two unknown quantum states.This protocol has following advantages: compile with traditional secret sharing,the new scheme can resist the Shor algorithm by using of quantum communication technology;without particle entangled state,the protocol can reduce the complexity of implementation;if there exists attacker or malicious participant,the new protocol can discover the situation,and it can avoid recover the wrong secret.
