| 1 | 量子计算与量子密码的原理及研究进展综述显示文摘量子计算与量子密码是基于量子效应的计算技术和密码技术.1984年Bennett和Brassard提出了第一个量子密钥分发协议,开启了量子密码学的研究,此后相继在量子加密、量子签名等领域进行了大量研究.1994年,Shor利用量子Fourier变换,设计了第一个实用的量子算法,在多项式时间内对大整数进行因子分解.1996年,Grover提出了量子搜索算法,能够对无结构数据进行二次加速.Shor算法和Grover算法的提出不仅体现了量子计算的优越性,还对传统基于数学困难问题的密码学体制造成威胁.经过半个世纪的发展,量子计算与量子密码在理论与实践的研究上都取得了丰硕的成果.从量子力学的数学框架、基本概念和原理、量子计算基本思想、量子密码研究进展及主要思想等方面进行总结梳理. | 王永利 徐秋亮 | 2020 | 计算机研究与发展2020，57，10： | 17 |
| 2 | Analysis of a kind of quantum cryptographic schemes based on secret sharing显示文摘Recently, Yang et al. proposed a kind of quantum cryptographic schemes based on secret sharing. The main idea is drawn from the case, where any n participants who share a secret K can co-operate as K does. This process can be applied to encryption, authentication, signature and so on. Unfortunately, since there is no identity authentication of the share's holder, these schemes inherit the limitation of secret sharing in practice. If some participants do not follow the protocol, the protocol would be a failure at last. Moreover, these schemes encounter another serious attack. Any two participants can co-operate to defeat the schemes by sending different shares to the parties unknown to the distributor of the secret K, such that these parties can execute the protocol as well. The attack proves that it is not enough for quantum cryptographic schemes that only the secret key is secure. | ZHANG XingLan1 & JI DongYao2 1 College of Computer Science and Technology, Beijing University of Technology, Beijing 100124, China 2 State Key Laboratory of Information Security, Graduate University of Chinese Academy of Sciences, Beijing 100049, China | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，9： | 8 |
| 3 | Quantum proxy signature scheme with public verifiability显示文摘In recent years, with the development of quantum cryptography, quantum signature has also made great achievement. However,the effectiveness of all the quantum signature schemes reported in the literature can only be verified by a designated person.Therefore, its wide applications are limited. For solving this problem, a new quantum proxy signature scheme using EPR quantumentanglement state and unitary transformation to generate proxy signature is presented. Proxy signer announces his public key whenhe generates the final signature. According to the property of unitary transformation and quantum one-way function, everyone canverify whether the signature is effective or not by the public key. So the quantum proxy signature scheme in our paper can be publicverified. The quantum key distribution and one-time pad encryption algorithm guarantee the unconditional security of this scheme.Analysis results show that this new scheme satisfies strong non-counterfeit and strong non-disavowal. | ZHOU JingXian ZHOU YaJian NIU XinXin YANG YiXian | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，10： | 6 |
| 4 | The security analysis of a threshold proxy quantum signature scheme显示文摘In the YW threshold proxy quantum signature scheme proposed by Yang and Wen,it is found that the basic signature key is the same as the basic verification key,which means that the bitwise exclusive OR(XOR) of the t proxy signature keys is exactly the XOR of the t proxy verification keys.Therefore,the proxy signers can deny their signature and the specific verifiers can forge a legal signature.Furthermore,an attacker can obtain a legal threshold proxy signature for an arbitrary new message.These findings show that there are hidden security loopholes that should be carefully constructed in designing more efficent YW-scheme. | SHI JianHong ZHANG ShengLi CHANG ZhengGang | 2013 | Science China Chemistry2013，56，3： | 5 |
| 5 | 一种新型弱仲裁量子签名方案显示文摘弱仲裁量子签名的安全性依赖于量子力学的一些基本原理,其不仅比传统的数字签名具有更好的安全性,而且比仲裁量子签名计算效率较高.为此,给出了一种新型弱仲裁量子签名,该签名具有以下特点:(1)仲裁者并不参与签名的产生和验证过程,只在发生纠纷时,仲裁者才参与纠纷的解决;(2)通过利用签名者身份信息以及与密钥绑定的旋转算子对签名进行认证,可以抵抗伪造攻击,并具有不可否认性;(3)该签名方案具有基于身份的数字签名方案的优点,即用户的身份信息直接用作公钥,无须量子公钥证书,这将给用户提供更多的方便. | 辛向军 黄守佳 张阳 化小林 李发根 | 2017 | 河南师范大学学报(自然科学版)2017，45，4： | 0 |
| 6 | 一种可多人验证的量子多重代理盲签名方案显示文摘多数情况下签名者只有一个人。当原始签名人无法亲自签名时,为了保证文件的有效性、防止权利过于集中,他可以委托多个人对文件进行签名和验证。方案采用量子密钥分发协议保证安全性,并利用幺正变换进行签名和验证,对签名和验证的顺序没有要求,并且签名和验证人数可以不同,提高了工作效率.正确性和安全性分析表明该方案技术实现简单,能够抵御主动和被动攻击,是一种安全的可实现量子多重代理盲签名方案。 | 姚洪迪 邹海 杜成斌 | 2016 | 量子电子学报2016，33，6： | 0 |
