The sizing of the optimized airship is closed to that of the high altitude airship published by Lockheed Martins Inc, which shows that the optimization model for the winged airship is accurate, and is of reference value for the configuration design in low speed near space aerial vehicle.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133811034","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}

Their protocol support users to join or leave the group at any time and the session key will be changed with the users' dynamic changes. In this paper, we point out that Zeng Ping et al.'s Group Key Agreement protocol is non-authenticated and easy to be forged or modified. Then we give a method that attacker can force all group members accepted the modified session private key in BR security model. So, It means that the Zeng Ping et al.'s Protocol can not meet the attribute of implicit key authentication and key control. Finally, we propose an improved protocol to overcome this problem.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121176522","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}

Among existing collusion resistant fingerprinting schemes, spread spectrum (SS) orthogonal fingerprinting has the best collusion resistance in non-blind detection, but in blind detection it shows inadequate performance. In this paper, we propose a novel quantization based orthogonal fingerprinting (QOFP) scheme that possesses good performance in non-blind and blind scenarios. To generate one fingerprinted copy, we implement subtractive dither quantization to the host signal with a dither sequence. By letting the elements in all dither sequences follow independent and identically distributed uniform distribution over a quantization step size, we make fingerprints embedded in different copies mutually orthogonal. Compared with SS orthogonal fingerprinting, our proposed QOFP has almost identical collusion resistance in non-blind detection and much better collusion resistance in blind detection.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114545728","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}

The ballistic missile is a typical space reentry vehicle, and it flights along a destined trajectory with a high speed and may maneuver. The motion of the ballistic mission can be approximated by the interaction of the basic motion models that have the simpler forms, and can be observed through using ground radars and optical sensors. After the approximate motion models and observations are brought into the framework of UKF who aims at nonlinear estimation problems specially, the estimate track of the ballistic missile can be implemented. This paper describes the motion model of the ballistic missile firstly, and then the measurement equations of the different sensors and the basic model of the motion body are given out, and then the algorithms of interacting multiple model and UKF are expatiated on, and finally the estimate track is achieved in a simulation system and a conclusion is drawn.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125381648","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}
