These include a monopole and a patch antenna. Each one of these structures is modeled and numerically tested using HFSS code. The testing procedure involves antenna simulation in the proximity of the human head. The behaviour of each antenna is evaluated for variable distances from the head geometry. Continuous waveform, representative of the sources used in mobile telephones, (250 mW) is used as the form of the antenna excitation. The SAR levels for the head tissues are calculated for and with accordance to the two currently accepted standards: Federal Communications Commission (FCC) and International Commission on Non-Ionizing Radiation Protection (ICNIRP). The computed SAR levels within each of the considered tissues vary for the two antennas under investigation.","PeriodicalId":432307,"journal":{"name":"2008 New Technologies, Mobility and Security","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124761788","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}

They guarantee good security performance at low processing and energy costs. However, unlike traditional implementations, they are vulnerable to side channel attacks. Particularly, fault attacks have proved their efficiency in cracking hardware implementation of some robust symmetric and asymmetric encryption algorithms. In this paper, we develop an FPGA version of the attack proposed by Piret and Quisquater against the AES (Advanced Encryption Standard) algorithm. Through temporal and spatial analyses of the rounds that have been affected by the fault injection process, we adapt the aforementioned attack to our context. The results obtained in this paper can serve to design a more secure FPGA implementation of AES.","PeriodicalId":432307,"journal":{"name":"2008 New Technologies, Mobility and Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129124081","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}

These attacks require simpler technical resources than tampering or cryptanalysis and, they cannot be prevented by ordinary security protocols that operate in the high layers of the protocol stack. Distance bounding protocols, which are tightly integrated into the physical layer, are the main countermeasure against them. Hancke and Kuhn's protocol was the first distance bounding protocol for RFID. Tu and Piramuthu have recently proposed another protocol which outperform it. More precisely, the authors claim that their protocol reduces the false acceptance ratio and is resistant to terrorist attack. In this paper, however, we analyse this protocol and, discuss some aspects that could question its effectiveness.","PeriodicalId":432307,"journal":{"name":"2008 New Technologies, Mobility and Security","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126859366","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}

In this paper, new efficient models are developed and evaluated for analyzing the security-related behavior of computing architectures and networks comprising complex interconnected communication systems adapted towards a generalized analysis. These models, based on Markov processes, allow calculation of critical security factors, related to intrusion detection, of such interconnected systems components and the evaluation of the associated security mechanisms. Although, at this step two interconnected systems are analyzed, the systematic model introduced allows for a generalized model of N interconnected systems. We herein show the principles of such an analysis. Security parameters calculation and Security mechanisms evaluation may support the risk analysis and the decision making process in resolving the trade-offs between security and quality of service characteristics corresponding to the complex interconnected computing and communication systems.","PeriodicalId":432307,"journal":{"name":"2008 New Technologies, Mobility and Security","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132115639","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}

Using this technology one can create opportunities for the learner to get knowledge whenever and wherever it is required. For better and accurate delivery of knowledge, it is very important to enhance quality, availability and processing of current training systems. E-learning should be adaptive and in accord with the requirement of the learner. A course should be designed on the basis of student's background, interests and aptitude. Much has been written on the contents' management of e-learning based on theoretical knowledge. Likewise, much has been written on the contents' delivery issues in e-learning but less effort has been made regarding e-learning, based on experimental knowledge.

The adaptation process is a combination of on stock and on demand adaptation. The aim is to have a balance between the two methods to optimize the adaptation process. Unlike other existing platforms, our system gives the possibility to the user to begin the visualisation of the multimedia presentation before the end of the adaptation process, thus reducing user waiting time.","PeriodicalId":432307,"journal":{"name":"2008 New Technologies, Mobility and Security","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115635158","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}
