th This book contains the best papers of the 5 International Conference on e-Business and Telecommunications (ICETE), which was held in July 2008, in Porto, Portugal. This conference reflects a continuing effort to increase the dissemination of recent research results among professionals who work in the areas of e-business and te- communications. ICETE is a joint international conference integrating four major areas of knowledge that are divided into four corresponding conferences: ICE-B (- ternational Conf. on e-Business), SECRYPT (International Conf. on Security and Cryptography), SIGMAP (Int'l Conf. on Signal Processing and Multimedia) and WINSYS (International Conf. on Wireless Information Systems). The program of this joint conference included several outstanding keynote lectures presented by internationally renowned distinguished researchers who are experts in the various ICETE areas. Their keynote speeches have contributed to heightening the overall quality of the program and significance of the theme of the conference. The conference topic areas define a broad spectrum in the key areas of e-business and telecommunications. This wide-view reporting made ICETE appealing to a global au- ence of engineers, scientists, business practitioners and policy experts. The papers - cepted and presented at the conference demonstrated a number of new and innovative solutions for e-business and telecommunication networks and systems, showing that the technical problems in these closely related fields are challenging and worthwhile - proaching an interdisciplinary perspective such as that promoted by ICETE.
