In a cloud environment, location of data is generally maintained by a third party (service provider/vendor) and hence an individual has no control over its own data. In this context, data privacy is an important issue for cloud computing both in terms of legal compliance and user trust. In this paper, an approach for data privacy in hybrid cloud environment is focused. Initially, a data privacy model for cloud computing is provided in which sensitive and non-sensitive data are maintained separately. In order to maintain data privacy, an authentication monitor is introduced in this privacy model. Finally, the authentication algorithm is implemented in a very small setup cloud environment and experimental results are provided at the end of the paper.","PeriodicalId":285986,"journal":{"name":"2011 2nd International Conference on Computer and Communication Technology (ICCCT-2011)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129442695","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}

Excessive high transmit power consumes more energy and increases internode interference significantly, while low transmit power may cause network failure. Thus choice of optimal transmit power is one of the prime concern in such network. Optimal transmit power is the minimum power required to sustain the network connectivity while maintaining a predetermined maximum tolerable Bit Error Rate (BER). In this paper, optimal transmit power is derived for a WSN deployed based on a random topology. Further impact of Rayleigh fading on optimal transmit power, route BER and energy consumption for successful delivery of data in multihop using ARQ in each hop is studied for such random WSN. In random network, an intermediate node in the route selects the nearest node within a sector of angle (θ) towards the direction of the destination as the next hop. The effects of search angle (θ) on optimal transmit power, route BER performance and energy consumptions are also indicated.","PeriodicalId":285986,"journal":{"name":"2011 2nd International Conference on Computer and Communication Technology (ICCCT-2011)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127144114","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}

Web based environment for these experiments helps the learners with any time accessibility of the remote hardware resources through online environment. The graphical programming language LabVIEW and data acquisition facilities provide an attractive solution through the availability of rich functions to acquire and analyze the signals. The custom interface circuits are designed to configure the circuit remotely based on the design requirement. The remote switching of different components to the circuit experimentation is achieved through the transistor switching circuitry. The switching circuitry is operated by the Boolean control actuations on graphical user interface, which can be remotely operated through a common web browser.

In present era, the Internet is considered as main infrastructure of the global information society. Therefore, the availability of Internet is very critical. Distributed denial-of-service (DDoS) attacks pose an immense threat to the availability of these services. The services are severely degraded and hence lot of business loses are incurred due to these attacks. To objectively evaluate DDoS attack's impact, its severity and the effectiveness of a potential defense, a precise, quantitative and comprehensive DDoS impact metrics that are applicable to web services are required. In this paper, network topology is emulated and Flash Event (legitimate web traffic at high Rate) is generated. The attack traffic is generated at different strengths using different protocols to measure attack impact on web service. The impact is measured in terms of metrics such as Throughput, Response Time, Active Connections, Percentage of Failed transactions, Legitimate Packet Survival Ratio; Percentage of Packets Lost, Percentage of Request Packets Lost and Bottleneck Bandwidth","PeriodicalId":285986,"journal":{"name":"2011 2nd International Conference on Computer and Communication Technology (ICCCT-2011)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125271990","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}

It uses RC4 for pn-sequence generation and the same is xored with the plain text and added integrity check value produced by the CRC-32. In this paper, the WEP has been implemented using the Linear Feedback Shift Register (LFSR) as a pn-sequence generator, i.e., the RC4 in WEP has been replaced by LFSR. Also the static key used in WEP is replaced by a dynamic key; as a result the proposed WEP implementation is more secured than the original one. The pn-sequence generated by LFSR is more random than the pn-sequence generated by RC4. In this regard, a randomness test, called Diehard test, has been carried out on the outputs of both RC4 and LFSR, and it has been found that more tests are satisfied by the LFSR, the details test results are included in this paper for ready reference.","PeriodicalId":285986,"journal":{"name":"2011 2nd International Conference on Computer and Communication Technology (ICCCT-2011)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134134115","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}

White box testing is primarily of two kinds-static and structural. Whereas static testing requires only the source code of the product, not the binaries or executables, in structural testing tests are actually run by the computer on built products. In this paper, we propose a technique for optimizing static testing efficiency by identifying the critical path clusters using genetic algorithm. The testing efficiency is optimized by applying the genetic algorithm on the test data. The test case scenarios are derived from the source code. The information flow metric is adopted in this work for calculating the information flow complexity associated with each node of the control flow graph generated from the source code.
