Many researches have been done in the virtual environment to detect and defend such attacks. But a data flow is essentially needed to verify these researches in a real environment. This paper proposes a simulation platform of distributed denial of service attacks based on network processor. The fractal Brownian motion model is introduced to generate attack flow with the characteristic of self-similarity. A transmission control mechanism based on micro-engine is presented to reduce the error of output data flow¿s Hurst parameter. Experiment results show that the model can generate a high speed self-similar attack flow with controllable Hurst parameter, and different kinds of traffic in the flow can be accurately transmitted as configured.","PeriodicalId":255247,"journal":{"name":"2008 International Conference on Computational Intelligence and Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115707525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our original MCPSO, there is no information sharing among slave swarms except that the information of the best performing particle is broadcasted to the master swarm. To deal with this issue in MCPSO-CC the population is divided into several identical sub-swarms and a center communication strategy is used to transfer the information among all the sub-swarms. To demonstrate the efficiency of the proposed MCPSO-CC algorithm, its performance is compared with SPSO and MCPSO on four well-know benchmark functions. Experimental results show that MCPSO-CC achieves not only better solutions but also faster convergence.","PeriodicalId":255247,"journal":{"name":"2008 International Conference on Computational Intelligence and Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123410485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In practice, a large number of ratings from similar users are not available, due to the sparsity inherent to rating data. Consequently, recommendation quality can be poor. In this paper, we present an effective content semantic similarity boosted CF framework (CSSCF) for combining content meaning and collaboration. Our approach uses a content semantic similarity based rater (CSSR) to enhance existing user data, and then provides personalized suggestions through collaborative filtering. The new model is however more robust to data sparsity, because missing ratings are rated using the CSSR in advance. Experiments demonstrate that the proposed method gives better recommendations than pure collaborative filter.","PeriodicalId":255247,"journal":{"name":"2008 International Conference on Computational Intelligence and Security","volume":"797 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117040971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
