A novel approach using quantum chaos that could aid the cryptographers in the development of cryptographic design is proposed. The dynamics in quantum setup is analyzed through energy packets. The geometry that explains these coordinates is a Riemannian geometry with a line element given by a metric ds2 = gij dxi dxj, where xi is the position vector, gij is the fundamental metric of a covariant tensor of rank 2. With this fundamental form we obtain the difference equation for a geodesic. By allowing encryption to occupy the geodesic, we achieve time and space complexity of the systems.","PeriodicalId":429916,"journal":{"name":"2012 International Conference on Computing Sciences","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121577548","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}

This attack mainly makes use of the end to end congestion control mechanism of TCP. The proposed scheme uses symmetric key cryptography and modified SHA-1 (mSHA-1) hash function for verifying packet reordering. This is implemented with AOMDV routing protocol using NS-2 network simulator. The proposed solution blocks the attack after its detection. The efficiency of the proposed scheme is evaluated on different performance metrics like congestion window and TCP Good put as the attack mainly targets the congestion control mechanism of TCP.","PeriodicalId":429916,"journal":{"name":"2012 International Conference on Computing Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129201387","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 simulation models in a reliable and simple way can be developed by researchers using different simulators for evaluating the behavior and performance of protocols for different networks, simulations are a good example between cost and complexity by maintaining the accuracy of the results. This paper gives briefly survey on a performance comparison study of the different network simulators for wireless network. There are many simulators for wireless network, but among them five are the popular simulators these are: Qualnet/GlomoSim, OM-Net++, Ns-2, OPNET modeler and JSim with a real-world test bed. The information about each of the simulator abilities, their internal structure, development environment and their support for wireless network simulation has detailed discussed in this paper.

The proposed method exploits Hue-Saturation-Value (HSV) color space since the HSV space separates color from intensity. The hue and saturation components have been kept constant in order to avoid color distortion. In this work, the value component of the HSV has been modified in two steps. First, the non-linear transfer function is applied on the overlapping and non-overlapping window in order to enhance luminance part of the image. Further, the 2-D Gaussian filter has been used for contrast enhancement. The Gaussian filter enhances the darker pixel while neutralizing the over enhanced pixel. The modified value is combined with preserved hue and saturation components in order to obtain enhanced HSV image. Finally, the image from HSV color space is converted into RGB color space. The experimental results presented show that the color image enhanced by this algorithm is clearer, vivid and efficient.","PeriodicalId":429916,"journal":{"name":"2012 International Conference on Computing Sciences","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132961880","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 the various attacks possible in mobile ad hoc networks wormhole attack is one which is treated as a very severe attack. In this attack a malicious node records packets at one location in the network and tunnels them to another malicious node which is present in the other end of the network. In this paper, we have proposed an algorithm which detects and avoids the wormhole attack in the routing phase itself. Our mechanism is based on the total round trip time (RTT) of the established route and the average round trip times of the sender one hop neighbors, which is considered as maximum one hop round trip time. Our solution works for both mobile ad hoc networks and wireless ad hoc networks.","PeriodicalId":429916,"journal":{"name":"2012 International Conference on Computing Sciences","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114647946","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}

What they all have in common is that they operate as a stand-alone system rather than a scalable and shared user reconfigurable resource. The advent of cloud computing has changed the traditional HPC implementation. In this article, we will discuss a very successful production level architecture and policy framework for supporting HPC services within a more general cloud computing infrastructure. This integrated environment, called Virtual Computing Lab (VCL), has been operating at NC State since fall 2004. Nearly 8,500,000 HPC CPU-Hrs were delivered by this environment to NC State faculty and students during 2009. In addition, we present and discuss operational data that show that integration of HPC and non-HPC (or general VCL) services in a cloud can substantially reduce the cost of delivering cloud services (down to cents per CPU hour).","PeriodicalId":429916,"journal":{"name":"2012 International Conference on Computing Sciences","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126522233","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}

Therefore before implementing image based CAPTCHAs publicly, it is necessary to analyze the different complexity issues related to image based CAPTCHAs.

Web Services are acting the core component for Web 2.0 and related technologies. jQuery is the new industry standard that has redefined ways of client side programming. Programmers writing multiple lines of code in JavaScript, now can really unleash the power of jQuery with few lines of code. Also they can make use of Ajax calls and JSON support in invoking of web services. jQuery is now acting as an industry standard as big top IT companies are supporting jQuery in their product(s). jQuery also helps in removing biggest problem of multiple page post backs through client side scripting. Through this any web developer can use the Ajax based update of the page which can partially update the page asynchronously without any post back.
