Duringthelastfewyearsweseenetworkandinformationsystemsecurityplaying an increasingly important role in our everyday lives. As our computers continue to get infested by all sorts of malware, and as our networks continue to choke with spam and malicious tra?c, we see more and more people losing their co- dence in information technologies as they get signi?cantly concernedabout their security as well as their privacy and that of their loved ones. In their e?ort to cope with the problem, scientists, managers, and politicians all over the world havedesignedandarecurrently implementing systematicapproachesto network and information security, most of which are underlined by the same principle: there is much more room for improvement and research. Along the lines of encouraging and catalyzing research in the area of c- munications and multimedia security, it is our great pleasure to present the proceedings of the 10th IFIP TC-6 TC-11 Conference on Communications and MultimediaSecurity(CMS2006),whichwasheldinHeraklion,CreteonOctober 19-21, 2006. Continuing the tradition of previous CMS conferences, we sought a balanced program containing presentations on various aspects of secure c- munication and multimedia systems. Special emphasis was laid on papers with direct practical relevance for the construction of secure communication systems. The selection of the program was a challenging task. In total, we received 76 submissions, from which 22 were selected for presentation as full papers.
