Attacks and Improvement of Quantum Sealed-Bid Auction with EPR Pairs

Communications in Theoretical Physics 2014年第6期61卷 686-690页

作者：刘文杰王芳季赛瞿治国王小军 Jiangsu Engineering Center of Network Monitoring Nanjing University of Information Science & Technology School of Computer and Software Nanjing University of Information Science & Technology School of Electronic Engineering Dublin City University

Recently, an experimentally feasible three-party quantum sealed-bid auction protocol based on EPR pairs [Z.Y. Wang, Commun. Theor. Phys. 54 （2010） 997] was proposed. However, this study points out Wang＇s protocol cannot resist some internal bidders＇ attacks, such as the Twiee-CNOT attack, the collusion attack. A malicious bidder can launch the Twice-CNOT attack to obtain the other＇s bid, or the dishonest auctioneer may collude with one bidder and help him/her win the action by changing his/her bid. For preventing against these attacks, a simple solution by using the QKD-based message encryption and a post-confirmation mechanism by adopting the hash function are proposed.

International Journal of u- and e- Service, Science and Technology 2015年第4期8卷 265-278页

At present, event detection technologies have become an important part in building efficient wireless sensor networks. One of the popular and excellent event detecting algorithms is the improved Neighbor-based Fuzzy Logic algorithm, namely INFLE, which belongs to machine learning technology. However, there may be some false positives when fire has not spread to the detected node. In this paper, we propose an improved spatial-based fuzzy logic event detection algorithm (ISFLE) to dramatically decrease the probability of false positives before fire has spread to the node. In our proposed ISFLE, we put “Distance” variable to the fuzzy logic system to determine node’s final state. The simulation results validate that our proposed ISFLE outperforms traditional INFLE in decreasing the number of false positives. © 2015 SERSC.

Cryptanalysis and Improvement of Quantum Private Comparison Protocol Based on Bell Entangled States

Communications in Theoretical Physics 2014年第8期61卷 210-214页

作者：刘文杰刘超陈汉武李志强刘志昊 Jiangsu Engineering Center of Network Monitoring Nanjing University of Information Science & Technology School of Computer and Software Nanjing University of Information Science & Technology School of Computer Science and Engineering Southeast University College of Information Engineering Yangzhou University

Recently, Liu et al. [Commun. Theor. Phys. 57(2012) 583] proposed a quantum private comparison protocol based on entanglement swapping of Bell states, which aims to securely compare the equality of two participants' information with the help of a semi-honest third party(TP). However, the present study points out there is a fatal loophole in Liu et al.'s protocol, and TP can make Bell-basis measurement to know all the participants' secret inputs without being detected. To fix the problem, a simple solution, which uses one-time eavesdropper checking with decoy photons instead of twice eavesdropper checking with Bell states, is demonstrated. Compared with the original protocol,it not only reduces the Bell states consumption but also simplifies the protocol steps.

International Journal of Hybrid Information Technology 2015年第6期8卷 257-268页

作者： Wang, Baowei Su, Jianwei Zhang, Youdong Wang, Biqiang Shen, Jian Ding, Qun Sun, Xingming School of Computer and software Nanjing University of Information Science and Technology Nanjing210044 China Jiangsu Engineering Center of Network Monitoring Nanjing210044 China Department of Computer Engineering Huaiyin Institute of Technology Huaian223003 China Hubei Meteorological Service Center Wuhan430074 China

Wireless sensor networks are composed of numerous sensor nodes in the monitored area, which have been well applied in various practical areas. In these applications, data security from sensors has been threatened. Thereby in this paper, a digital watermarking based copyright protection method is proposed with regard to data security in wireless sensor networks. According to the particular characteristics of collecting data, the embedding capacity can be expanded using this method of manipulating both LSB and MSRB 4. bits of the data field. The data-related information is embedded as the digital watermarking into the data to be forwarded. When the base station receives the data, we use a lookup Table to improve the speed of data parsing. In order to achieve and verify the copyright protection on WSNs, both theoretical analysis and experimental results have demonstrated that the method can effectively detect the data reliability. In addition, we also generate two-dimensional code based on the test results, thereby facilitating the user's copyright authentication. © 2015 SERSC.

MapReduce is a popular programming model for the purposes of processing large data sets. Speculative execution known as an approach for dealing with the above problems works by backing up those tasks running on a low performance machine to a higher one. In this paper, we have modified some pitfalls and taken computer hardware into consideration (HWC-Speculation). We also have implemented it in Hadoop-2.6 and experiment results show that our method can assign tasks evenly, improve the performance of MRV2 and decrease the execution time.

An enhanced grouping proof for multiple rfid readers and tag groups

International Journal of Control and Automation 2014年第12期7卷 239-246页

作者： Shen, Jian Tan, Haowen Wang, Yang Ji, Sai Wang, Jin Jiangsu Engineering Center of Network Monitoring Nanjing University of Information Science and Technology Nanjing China Jiangsu Technology and Engineering Center of Meteorological Sensor Network Nanjing University of Information Science and Technology Nanjing China School of Computer and Software Nanjing University of Information Science and Technology Nanjing China

RFID authentication on large numbers of tags or tag groups has attracted many researchers' attention as an extension of initial one-or-two-tags scenarios. Due to demands of RFID application in supply chain, various proofs are proposed in the purpose of solving existing problems of grouping tags identification. However, it is proved that verifiers in these proofs are not aware of abnormal relating devices instantly, which may cause both security and technical risks and lie heavy upon identification of the problematic tags and readers. In this paper, we propose an enhanced grouping proof for multiple RFID readers and tag groups, according to which the verifier is able to cope with multiple readers and tag groups simultaneously and know the detailed status of the problematic tags. In addition, privacy protection is provided by offering mutual authentication between the readers and tags. Moreover, it is hard for the malicious tags to pass the verification in the proposed proof. © 2014 SERSC.

So far, cloud storage has been accepted by an increasing number of people, which is not a fresh notion any more. It brings cloud users a lot of conveniences, such as the relief of local storage and location independent access. Nevertheless, the correctness and completeness as well as the privacy of outsourced data are what worry could users. As a result, most people are unwilling to store data in the cloud, in case that the sensitive information concerning something important is disclosed. Only when people feel worry-free, can they accept cloud storage more easily. Certainly, many experts have taken this problem into consideration, and tried to solve it. In this paper, we survey the solutions to the problems concerning auditing in cloud computing and give a comparison of them. The methods and performances as well as the pros and cons are discussed for the state-of-the-art auditing protocols.

Cloud storage brings convenient storage of data, at the same time there are also hidden security issues. Data storage security includes legal access to the data stored in the cloud, namely access authorization and authentication security data sharing and the encryption of stored data to ensure data confidentiality, consisting of the accessibility to effective cryptographic data and inaccessibility to the deleted cryptographic data, using tamper-proof technology to ensure the integrity of the data, as well as using tracking technology to ensure data traceability. This paper focuses on the file systems with secure data deletion. We design a file system which supports secure deletion of data. It uses CP-ABE which supports fine-grained access policy to encrypt files. © 2014 IEEE.

Ciphertext-Policy Attribute-based Encryption (CP-ABE) is one of the most suitable technologies for data access control in cloud storage systems. This paper firstly presents the Attribute-based Encryption (ABE), secure deletion and secret-sharing schemes. Then we construct a CP-ABE model using secret-sharing methods to insure its security. At last, we propose an improved scheme on Data Access Control for Multi-Authority Cloud Storage Systems DAC-MACS to insure the security of the central authority (CA). © 2014 IEEE.
