The Transmission Control Protocol (TCP) is expected for use as a very secure host-to-host protocol linking hosts in packet-switched computer transmission networks, and in interconnected frameworks of such networks. computer communication systems are playing an increasingly important role in the military, government, and civilian environments. TCP gives a reliable data transfer service by receiving an acknowledgement from the target while transferring any segment from the source TCP is applied for both mass data transfer and interactive data applications. TCP is the primary transportation protocol in use inside maximum IP networks and helps the transfer of upper 90 percent of whole traffic across the public Internet now. Granted this principal role for TCP, the execution of this protocol forms a vital part of the entire picture of service performance for IP networks. So we improved TCP performance by reducing the number of acknowledgement (ACK) for each sending packet from the source to the destination machine, and it can help a router performance.

In this paper, the quaternion discrete Cosine transform (QDCT) is applied to the color image encryption technology, and partial encryption technique of color image based on QDCT is proposed. Obtained the QDCT spectrum of color image by QDCT, the real and imaginary parts of QDCT coefficients are quantized and encoded with the color image quantization coefficient table and QDCT coefficients encoding method, and part of low and high frequency coefficients are encrypted in the encoding process. Simulation results and security performance analysis shows that the proposed scheme can obtain the effect of secure image encryption, reduce the amount of encryption data and transmission data, and well distribute the pixels of the original image when only part of the data are encrypted. What’s more, the proposed scheme can decrypt and recover the original image with high quality. Due to the large key space, the proposed scheme can resist exhaustive attacks. © 2015 SERSC.

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.

With the rapid development of the Internet, the application of data mining in the Internet is becoming more and more extensive. However, the data source’s complex feature redundancy leads that data mining process becomes very inefficient and complex. So feature selection research is essential to make data mining more efficient and simple. In this paper, we propose a new way to measure the correlation degree of internal features of dataset which is a mutation of mutual information. Additionally we also introduce Hoeffding inequality as constraint of constructing algorithm. During the experiments, we use C4.5 classification algorithm as test algorithm and compare HSF with BIF(feature selection algorithm based on mutual information). Experiments results show that HSF performances better than BIF[1] in TP and FP rate, what’s more the feature subset obtained by HSF can significantly improve the TP, FP and memory usage of C4.5 classification algorithm. © 2015 SERSC.

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.

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

引用

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.

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

引用

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.

An enhanced grouping proof for multiple rfid readers and tag groups

International Journal of Control and Automation

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.

Improved locality-sensitive hashing method for the approximate nearest neighbor problem

引用

Chinese Physics B 2014年第8期23卷 217-225页

作者：陆颖华马廷淮钟水明曹杰王新 Abdullah Al-Dhelaane Jiangsu Engineering Center of Network Monitoring Nanjing University of Information Science & Technology School of Computer & Software Nanjing University of Information Science & Technology School of Economic & Management Nanjing University of Information Science & Technology Huafeng Meteorological Media Group Computer Science Department College of Computer and Information Science King Saud University

In recent years, the nearest neighbor search （NNS） problem has been widely used in various interesting applications. Locality-sensitive hashing （LSH）, a popular algorithm for the approximate nearest neighbor problem, is proved to be an efficient method to solve the NNS problem in the high-dimensional and large-scale databases. Based on the scheme of p-stable LSH, this paper introduces a novel improvement algorithm called randomness-based locality-sensitive hashing （RLSH） based on p-stable LSH. Our proposed algorithm modifies the query strategy that it randomly selects a certain hash table to project the query point instead of mapping the query point into all hash tables in the period of the nearest neighbor query and reconstructs the candidate points for finding the nearest neighbors. This improvement strategy ensures that RLSH spends less time searching for the nearest neighbors than the p-stable LSH algorithm to keep a high recall. Besides, this strategy is proved to promote the diversity of the candidate points even with fewer hash tables. Experiments are executed on the synthetic dataset and open dataset. The results show that our method can cost less time consumption and less space requirements than the p-stable LSH while balancing the same recall.
