Cryptology and network security

The 9th International Conference on Cryptology and Network Security (CANS 2010) was held in Kuala Lumpur, Malaysia during December 12–14, 2010. The conference was co-organized by the Multimedia University (MMU), Malaysia, and Universiti Tunku Abdul Rahman (UTAR), Malaysia. The conference received 64 submissions from 22 countries, out of which 21 were accepted after a careful and thorough review process. These proceedings also contain abstracts for two invited talks. All submissions were reviewed by at least three members of the Program Committee; those authored or co-authored by Program Committee members were reviewed by at least ? ve reviewers. P- gram Committee members were allowed to use external reviewers to assist with their reviews, but remained responsible for the contents of the review and r- resenting papers during the discussion and decision making. The review phase was followed by a 10-day discussion phase in which each paper with at least one supporting review was discussed, additional experts were consulted where needed, and ? nal decisions were made. We thank the Program Committee for their hard work in selecting the p- gram. We also thank the external reviewers who assisted with reviewing and the CANS Steering Committee for their help. We thank Shai Halevi for use of his Web-Submission-and-Review software that was used for the electronic s- mission and review of the submitted papers, and we thank the International Association for Cryptologic Research (IACR) for Web hosting of the software.
