Its speed and programmability are the main characteristics determining its performance. Therefore, for a design to be competitive, its processor has to fit the following characteristics: relatively inexpensive, flexible, adaptable, fast, and reconfigurable. A solution to this is the use of Field-programmable gate arrays (FPGA) as design tool. This paper describes the realization of an 8-bit FPGA based simple processor. Our system was implemented on the Xilinx Spartan 3 xc3s200FT256 using ISE foundation 8.1 and VHDL. 132 (6%) of the slices, 351 Bels were used. A maximum frequency of 95.364 MHz was reached with a minimum period of 10.486 ns.","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132347904","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 measured impedance is greatly influenced in the presence of SSSC on the line or even in the case of SSSC installation on the adjacent lines, near end of the line behind. The measured impedance at the relaying point depends on many factors including the power system structural conditions, pre-fault loading, the fault resistance, and SSSC structural and controlling parameters.","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125676481","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 particularly addresses the issues related to the PC weaknesses like the combination of key loggers and spyware software. The device uses exclusively symmetric encryption (AES) that ties the device directly to the payment server base at fabrication time. The device is connected to the PC through the USB interface from which it takes its power. The platform architecture is built around three entities: a I/O processor (IOP) responsible for the communication and user interface and a management of keys processor (MKP), responsible for all of the messages processing. Encryption is assured by a dedicated hardware engine for increased performance. The device is made known to the payment server at fabrication time through the assignment of a device ID. Both the server and the device will use secret keys known only to the two parties. This way, the authentication and security are guaranteed at the source. The device ID along with the device and server set of keys are assembled in a data storage packet, scrambled, encrypted by a completely secret device internal key, and stored on a local serial EEPROM. Moreover, the EEPROM setting procedure is a one way procedure where no way of reading back the clear device ID and set of keys is available. The strength of this approach is the fact that the device ID is associated with a set of device keys within the payment server database.","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114773914","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}

However, encryption algorithms are computation-intensive and power-hungry operations for portable devices, which have computing resource limits and energy constraints. Choosing a suitable encryption-decryption algorithm to implement in portable devices is an important decision that needs to be made in order to secure the exchange of sensitive information without over utilizing the power source, processor and memory in mobile devices. This paper provides a methodology to comprehensively evaluate encryption/decryption algorithms for portable devices based on energy, delay, and footprint. Our result is based on four cutting edge algorithms: RC6, Serpent, Mars, and Twofish, and can help to analyze the power and resource overhead of encryption/decryption, as well as other applications running on mobile devices.","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121048074","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}

Proposed techniques so far mostly are to provide protection for the banks or other enterprise corporations and/or require changes in Web servers. Regular home users are left without protection against phishing, other than the traditional rudimentary email filtering. Furthermore, security toolbars on browsers have been shown to be not effective. In this paper, we propose a light-weight user white list technique to provide protection for home users. We argue that for home users, white listing is advantageous over blacklisting, a popular technology. We show it is effective and efficient while imposing little burden on users and requiring no modification of servers.","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127349250","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 analysis shows that the thermally induced \"zero-pole doublet\" in the transfer function of the output impedance of current mirrors can show peaking in the frequency response, near the thermal cutoff frequency unless design constraints are imposed. Analytical expressions of output impedance, Zo(s), for the most prevalent current mirrors are derived incorporating thermal effects, and design recommendations are proposed to mitigate such effects. The effects of dynamic self-heating have been demonstrated through simulations in current mirrors using the Vertical Bipolar Inter-Company (VBIC) model in the SPECTRE simulator. The simulation result agrees within 10.0% with the theoretical model.","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"359 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115470079","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}

Though SoD has been studied by many researchers, most of them are concerned with specifications of various types of SoD constraints for policy enforcement. For large organizations that employ SoD policies, the ability to automatically verify if a given user-role assignment complies with SoD policies is of the great value for security management. This paper proposes an algorithm for constraint checking of simple dynamic SoD. Unlike most previous work that enforces SoD policy at run time (when roles are activated), our approach examines policy enforcement build-time (prior to run rime, i.e. when roles are assigned to users but not activated).","PeriodicalId":410786,"journal":{"name":"2008 IEEE Region 5 Conference","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122504389","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}
