Information Security and Cryptology - Third SKLOIS Conference, Inscrypt 2007, Xining, China, August 31 - September 5, 2007, Revised Selected Papers (Paperback, 2008 ed.)

The Third SKLOIS Conference on Information Security and Cryptology (- scrypt2007)wasorganizedbytheStateKeyLaboratoryofInformationSecurity of the Chinese Academy of Sciences in cooperation with Qinhai University for Nationalities. This international conference was held in Xining, Qinhai Province of China, and was sponsored by the Institute of Software, the Chinese Academy of Sciences, the Graduate University of the Chinese Academy of Sciences and the National Natural Science Foundations of China. By now, Inscrypt (the International SKLOIS Conference on Information - curity and Cryptology) has become a tradition, and it is, in fact, a leading event in this area, which takes place annually in China. We are pleased with the continuous support by authors, committee members, reviewers, sponsors and organizers. Indeed, the research areas covered by Inscrypt are important, since modern computing (including communication infrastructures and applications) requires increased security, trust, safety and reliability. This need has motivated the research community worldwide to produce important fundamental, exp- imental and applied work in the wide areas of cryptography and information securityresearchin recent years.Accordingly, the programof Inscrypt 2007c- ered numerous ?elds of research within these general areas
