The existence of a system that guarantees the trustworthiness of these announcements seems necessary. The proposed approach generating announcements should be preserved from internal and external attackers that attempt to send fake messages. In this paper, we use a group-based endorsement mechanism based on threshold signatures against internal attackers. We choose NTRUSign as a public key cryptosystem for decreasing signature generation and verification times. This approach optimizes the network overhead and consequently its performance. In this scheme, also the privacy of signers and endorsers that generate or endorse trustworthy announcements is preserved.","PeriodicalId":211301,"journal":{"name":"2010 International Conference on Electronics and Information Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115148363","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}

JPEG 2000 standard is developed to cater such application requirements. However, the sequential execution of the bit plane coder (BPC) used in this standard consumes more clock cycles. To improve the performance of the BPC, a new concurrent context modeling technique is proposed in this paper. To study number of context generated in each clock cycle, analysis is carried out on five ISO grayscale images with size 512 × 512. The study revealed that about 58% of time more than 4 contexts are generated in one clock. Therefore, a new concurrent context coding architecture is proposed in this paper. It is implemented on Startix FPGA and the hardware requirement is reduced significantly, compared to similar architectures. Moreover, number of clock cycles required to encode a bit plane is reduced by 10% and it is minimum 2.5 times faster than the similar designs in existence. This design operates at 164.47 MHz, which makes it compatible for encoding HDTV 1920 × 1080 4:2:2 at 39 frames per second.","PeriodicalId":211301,"journal":{"name":"2010 International Conference on Electronics and Information Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123040388","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 study focuses on the optimization of weights. The conventional BPNN uses the steepest descent method, i.e. a local optimization technique, to minimize an energy function (cost function) to find the BPNN weights. Therefore, a conventional BPNN cannot obtain global weights. An advanced simulated annealing (ASA) algorithm is a stochastic global method applied for solving a multi-dimensional objective function with boundary conditions. To overcome the drawback associated with the standard BPNN, this study attempts to optimize the weights of the BPNN using an ASA algorithm. Performance of the proposed ASA-based BPNN (named ASA-BPNN) is evaluated using a benchmark chaotic time series problem, i.e. the Mackey-Glass time series problem. Furthermore, the comparing experimental results for the ASA-BPNN with those of a standard BPNN reveals that training and generalization accuracies of the ASA-BPNN are superior to those of the standard BPNN for the test case.","PeriodicalId":211301,"journal":{"name":"2010 International Conference on Electronics and Information Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117178971","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}

Data has been collected from 1.500 qualitative responses to an open-ended question that requests (if there is) any other additional comment at the end of a quantitative survey. Collected data is categorized and analyzed with respect to subjective and practical criteria by the developers and operators of the gateway. Based on a maturity model classification for e-Government services from literature, selected examples of specific services are also provided. While the initial results reflect a positive perception of citizen users for the system, various suggestions and requests useful for development and improvement are especially noteworthy. For instance, citizen demand for more personalized information and service provision can be underlined. Findings from these initial survey outcomes are hoped to be not only incorporated into the e-Government service development in Turkey, but considered as useful for other ongoing practical and academic works on e-Government and ICT system evaluation in general, as well.","PeriodicalId":211301,"journal":{"name":"2010 International Conference on Electronics and Information Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120968125","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}
