| 3 | Survey on cyberspace security显示文摘Along with the rapid development and wide application of information technology, human society has entered the information era. In this era, people live and work in cyberspace. Cyberspace is the collection of all information systems; it is the information environment for human survival. Therefore, it is necessary to ensure the security of cyberspace. This paper gives a comprehensive introduction to research and development in this field, with a description of existing problems and some currently active research topics in the areas of cyberspace itself, cyberspace security, cryptography, network security, information system security and information content security. | ZHANG HuanGuo HAN WenBao LAI XueJia LIN DongDai MA JianFeng LI JianHua | 2015 | Science China(Information Sciences)2015，58，11： | 15 |
| 4 | A public key cryptosystem based on data complexity under quantum environment显示文摘Since the Shor algorithm showed that a quantum algorithm can efficiently calculate discrete logarithms and factorize integers, it has been used to break the RSA, EIGamal, and ECC classical public key cryptosystems. This is therefore a significant issue in the context of ensuring communication security over insecure channels. In this paper, we prove that there are no polynomial-size quantum circuits that can compute all Boolean functions(of which there are 22ncases) in the standard quantum oracle model. Based on this,we propose the notion of data complexity under a quantum environment and suggest that it can be used as a condition for post-quantum computation. It is generally believed that NP-complete problems cannot be solved in polynomial time even with quantum computers. Therefore, a public key cryptosystem and signature scheme based on the difficulty of NP-complete problems and the notion of data complexity are presented here. Finally,we analyze the security of the proposed encryption and signature schemes. | WU WanQing ZHANG HuanGuo WANG HouZhen MAO ShaoWu JIA JianWei LIU JinHui | 2015 | Science China(Information Sciences)2015，58，11： | 6 |

| 6 | DNA密码学研究进展与应用显示文摘作为密码学近年来衍生出的全新分支,DNA密码学诞生自DNA计算,以DNA分子为信息载体,充分利用DNA分子所具有的超高存储密度、超大规模并行运算能力、超低能耗等优点,可从分子水平实现加密、隐写及签名认证等功能.经过二十余年的发展,DNA密码学也从理论初步走向应用,研究贴近研究热点,比如结合图像加密的混合加密、用于签名认证的DNA水印技术等.DNA密码学是对基于数学难题的传统密码学的有益补充,但仍处于起步阶段,基于DNA分子的加密、隐写、签名认证等技术都具有很大的发展空间.DNA密码学仍未建立起完备的理论体系,发展也受到生物技术的制约.随着生物技术的进步,DNA密码学一定能在信息安全领域展示出自己巨大的潜力和能量. | 董校生 王雷 王燕 薛志东 | 2020 | 广州大学学报(自然科学版)2020，19，2： | 1 |
| 7 | Rational construction of a cellular memory inverter显示文摘Robust and reliable biological memory computing systems are lacking, although many biological computing systems are implemented. We successfully designed, constructed, and tested a cellular memory inverter in the bacterium Escherichia coli in a predictable way. We selected isopropyl-D-1-thiogalactopyranoside(IPTG) as the input and green fluorescent protein(GFP) as the output. We selected negative regulation of lac operon and excision function of Cre recombinase as computing tools. The GFP can express and produce output without IPTG. The input, IPTG, can induce the expression of Cre recombinase. The Cre recombinase can excise the GFP gene between site lox71 and site lox66, and hence turn off the output. We also selected ordinary differential equations(ODEs) to predict the dynamic behaviors for the precise design and implementation of the inverter. We used sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS-PAGE), colony Polymerase Chain Reaction(PCR), and fluorescent quantitative analysis techniques to verify the function of our inverter.The study provides a new biological memory computing system. The Cre recombinase functions used here should be useful in the construction of biological memory computing systems. | CHEN Mei ZHANG Lu XU Jin | 2015 | Science China(Information Sciences)2015，58，1： | 1 |
| 8 | DNA-chip-based dynamic broadcast encryption scheme with constant-size ciphertexts and decryption keys显示文摘In this paper we present DNA-DBE,a DNA-chip-based dynamic broadcast encryption scheme.In our scheme,new users can join dynamically without modification of other users’decryption keys.Either the ciphertext or the decryption key is of constant-size.Backward secrecy is achieved in DNA-DBE:if new users join the system dynamically,they will not be able to retrieve past data.The security of our scheme relies on hard biological problems,which are immune to attacks of new computing technologies in the future.There exists a special feature in DNA–based cryptosystems,i.e.the set of encryption keys and the set of decryption keys have a many-to-many relationship.The implementation of more complicated DNA cryptosystems taking advantage of this special feature has been previously left as an open problem.Our DNA-DBE system is a solution to this open problem,which is also the first exploration of DNA based group-oriented encryption system. | FANG XiWen LAI XueJia | 2014 | Science China(Information Sciences)2014，57，9： | 1 |
