Three-party key exchange protocol is an important technique for two clients to agree a session key with the help of a trusted server who shares a human password with each client. Many protocols have been proposed for the requirements of security and efficiency over the years. For security consideration, we are concerned with the off-line password-guessing attack. We make the attack to a three-party key exchange protocol based on Elliptic Curve Discrete Logarithm Problem(ECDLP) and show that it is vulnerable against the off-line password-guessing attack. In fact, the off-line password-guessing attack is available for malicious participants and is effective to similar protocols. To avoid this problem, we give a suggestion to eliminate it and enforce the security.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123639634","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}

Specifically, the basic voltage doubling rectifier circuit is analyzed, then the microwave voltage doubling rectifier circuit is derived in UHF band, and its main components and parameters are analyzed in detail. Lastly, the four-stages voltage doubling rectifier circuit of 900NHz is designed and simulated using ADS software.

In recent years, there have been numerous research on the performance analysis and model of DCF under the assumption that the transmission queue is always nonempty (i.e. saturation state). In this paper, we propose a dynamic priority back-up algorithm (DPBA) for IEEE802.11 DCF, the basic idea of DPBA is each node should collect statistical data of other node's transmission while sensing the channel, and maintaining a sending data table for all node in network. When the node has data to transmit, it will calculate the dynamic priority and connection window according to the number of successful sending, the number of successful sending and the statistical data in sending table. Simulation results show that DPBA can properly assign channel among nodes in proportion to their dynamic priority as well as enhance the network saturation throughput.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128690624","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}

M-payment applications are being developed for both online and in-store purchases. Near Field Communication (NFC) technology has the potential to greatly impact the way mobile devices are used. NFC is a short range wireless communication interface that allows for the integration of a mobile device in existing contactless application infrastructure, such as using a mobile phone to pay at Point-of-Sale (POS). It is important to provide a simple method for implementing m-payment systems that offer both reasonable security protection as well as ease of use for the user. We propose a system that combines the existing 3G cryptographic primitives and algorithms, in addition to the identification and authentication capabilities of the USIM, with NFC technology to implement a m-payment system. Such a system could easily be integrated into current 3G infrastructure and provide improved scalability and ubiquity for m-payment services. Our proposed scheme focuses on a conventional in-store payment environment, with mutual authentication between entities and a subsequent trustworthy transaction being achieved through 3G and USIM security services.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129377433","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 found that the majority of the Websites are still in the early stages of development, and there is a noticeable lack in Websites readiness for moving-up to the advanced level fundamental for providing transactional services. Based on the evaluation results and through a manual testing, it was found the majority of the Websites do not employ the same design, where there should be consistent and should be using the same standards and features.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130979769","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}

Thirdly, the combination of ant colony arithmetic with logistics network transport model is expounded, based on the similarity between logistics network transport model and Travelling Salesman Problem.
