Trusted network connect (TNC), whose goal is to improve network security from source, now has become hot topic in security domain. We proposed a new access model for the terminals without meeting the requirements in TNC specifications. Also we discussed the work flow and communication process of presented model. Simulations show that the feasibility of the presented model used in the scenario where terminals fall short of network demand can pass the access authentication of network with TNC specifications.

One of the most prevalent security problems in network is the rampant propagation of email worms. In this paper game theory is suggested as a method for modeling and computing the probabilities of expected behaviors of email users in the email worm propagation process. The game situation models the actions of the email users under the condition that at the time they open an attachment, the system may be infected. Results of email worm propagation simulation under a practical simulation environment show that well camouflaged worms spread more quickly and survive longer than naive worms, moreover, user's security consciousness and the update frequency of anti-virus software make great impact on email worm propagation.

There is myriad high quality information in the Deep Web and the feasible method to access the Deep Web is through the query interface of the Deep Web. It's necessary to extract abundant attributes and semantic relation description from the query interface. Automatic extracting attributes from the query interface and automatically translating a query is a solvable way for addressing the current limitations in accessing Deep Web data sources. We design a framework to automatically extract the attributes and instances from the query interface using the WordNet as a kind of ontology technique to enrich the semantic description of the attributes. Each attribute is extended into a candidate attribute set in the form of a hierarchy tree. At the same time, the hierarchy tree generated by ontology describes the semantic relation of the attributes in the same query interface. We carry out our experiments in the real-world domain. The results of the experiments showed the validation of query translation framework. © 2008 IEEE.

The Web has been dramatically deepened by the deep Web, which the traditional information fusion system shows disability to integrate. The myriad information hidden behind the deep Web attracts the considerable attention from the researchers. The key element in a deep Web information fusion system is the data source modeling problem, which determine the whole technical method of the whole system. The query interfaces provided by the deep Web are the clues to disclose the hidden schemas. But the complicated semantic relationships in the query interfaces lead to the low generality and ability of local as view (LAV) method in the traditional information fusion system. An approach of evaluating the semantic relationships between the attributes in the query interfaces by utilizing WordNet, a typical ontology technique, is presented in this paper. The semantic relationships between semantic related attributes are evaluated by the semantic calculating method of WordNet. The meaningless attributes is instantiated by instance information embedded in the interfaces in order to attach correlated semantic information. The experiment is carried out in the real life domains, and the result shows the efficiency of ontology based semantic evaluating method in LAV.

Information fusion is an interdisciplinary research field aiming to combine and merge the information or data from different information sources. The output of information fusion system is a global schema through which users can get information or data from different dispersed sources. To generate a deep Web information fusion system is facing many challenges, because the nature of Web is different from those of traditional databases and multi-databases. The major challenge in a deep Web information fusion system is the data source modeling problem, which determine the technical method of the whole system. The query interfaces provided by the deep Web are the clues to disclose the hidden schemas. But the complicated semantic relationships in the query interfaces lead to the lower generality and ability of local as view (LAV) method in the traditional information fusion system. We present an approach that the semantic relationships between semantic related attributes can be evaluated by the WordNet, a kind of ontology instrument. The experiment is carried out on the famous dataset, and the result shows the efficiency of ontology extended LAV of building mappings between local views and mediator schema.

With the myriad emergence of the online Web Database, the Web is divided into a two layers information platform which is composed of Surface Web and Deep Web. The huge information hidden in the Deep Web is higher in the quality than the Surface Web. This interests the researchers of the traditional Database community. In order to adapt the Web community, the idea of information fusion is further transformed. However, the nature of the Web is great different from the Database in structure, principle and function. Query reformulation is one of the technical challenges. The only accessible method to get the information in the Deep Web is through the query interfaces provided by the Website of Deep Web. There are many semantic restrictions between the attributes in the query interface. Some attributes are co-occurred and the others are exclusive sometimes. To generate a valid query, we have to reconcile the key attributes and their semantic relations. To address the problem, a method based on the HTML codes is presented in this paper. Different kinds of semantic containers can be got through analyzing the codes of the query interface. The experiment is carried out on the famous Dataset of Deep Web to show the feasibility of the method. ©2009 IEEE.

Ontology-based filling forms of deep web entries automatically

引用

Journal of computational Information Systems 2009年第6期5卷 1553-1560页

作者： Zuo, Wanli Wang, Ying Wang, Xin Ji, Wenyan Peng, Tao College of Computer Science and Technology Jilin University Changchun 130012 China Key Laboratory of Computation and Knowledge Engineering China College of Software Changchun Institute of Technology Changchun 130012 China

An increasing number of databases are becoming web accessible through form-based query interfaces, therefore, this paper proposes a novel method of filling forms on deep web data integration system, which contains three sub-models: query analyzer, query processor and query submission. Query analyzer is used to match each local interface schema and integration interface schema to judge the match type by ontology. Query processor is used to capture the matching relationships from query analyzer, and decompose the queries of integration interface which are submitted by users. Queries will be distributed and forms will be automatically translated to multi-database entries for implementing multi-databases searching under an integration interface, which is transparent to users in searching of multi-databases. Experiment result shows that this method of query translation is feasible. 1553-9105/ Copyright © 2009 Binary Information Press.

作者： Zhu, Xing-Jun Sun, Ji-Gui Zhang, Yong-Gang Li, Ying College of Computer Science and Technology Jilin University Changchun 130012 China Key Laboratory of Symbolic Computation and Knowledge Engineering Jilin University Changchun 130012 China

This paper studies the technique of preprocessing in constraint satisfaction problem (CSP). Firstly, we propose a notion of entirety singleton consistency (ESC) and the algorithm, and then analyze the time and space complexity and correctness. Based on this, we present a new preprocessing algorithm SAC-ESC based on ESC, and prove its correctness. Furthermore, we use the divide-conquer strategy for the algorithm to automatically adapt to domain partition of various problems. In our experiments on random CSPs, pigeon problems, N-queens problems and benchmarks, the efficiency of our algorithm SAC-ESC is 3-20 times those of the existing SAC-SDS and SAC-3.

ATP (automated theorem proving) has always been one of the most advanced areas of computer science. The traditional idea used in ATP is to try to deduce the empty clause to check satisfiability, such as resolution based theorem proving, which is one of the most popular methods. Extension-rule-based theorem proving is a new resolution-based theorem proving method. After a deep research work on the extension rule, a brilliant property of the rule is obtained. In this paper, the property and an algorithm which is used to decide it are proposed firstly. In addition, the algorithm's time complexity and space complexity are analyzed and proved. Based on the above work, a novel extension rule based theorem proving algorithm called NER is proposed. The NER algorithm transforms the problem which decides whether a clause set is satisfiable to a series of problems deciding whether one literal set includes another one, while the original extension algorithm transforms them to problems counting the number of maximum terms that can be expended. A number of experiments show that the NER algorithm obviously outperforms both the original extension rule based algorithm ER and the directional resolution algorithm DR. Especially, it can be improved up to two orders of magnitude.

Escrow mechanism for personal security keys on IBE

引用

Tongxin Xuebao/Journal on Communications 2009年第11 A期30卷 75-80页

作者： Zou, Yue-Peng Ouyang, Dan-Tong He, Li-Li Bai, Hong-Tao College of Computer Science and Technology Jilin University Changchun 130012 China Key Laboratory of Symbolic Computation and Knowledge Engineering of Ministry of Education Jilin University Changchun 130012 China

A new escrow mechanism for personal security keys on IBE was proposed. This mechanism constructed a security trust system composed of private key generator, key management center, and user security component to set up a personal security key escrow model, thus providing identity validation, confidentiality and integrality check for the application, backup, recovery, and renewal of the escrowed keys. The mechanism, taking advantage of the IBE, simplified the process of authentication and encryption, mede it possible for users to complete independently the escrow of personal security keys. Therefore, it is more practical than traditional key escrow schemes.
