ACNS2008, the6thInternationalConferenceonAppliedCryptographyandN- work Security, was held in New York, New York, June 3-6, 2008, at Columbia University. ACNS 2008 was organized in cooperation with the International - sociation for Cryptologic Research (IACR) and the Department of Computer Science at Columbia University. The General Chairs of the conference were - gelos Keromytis and Moti Yung. The conference received 131 submissions, of which the Program Committee, chairedbyStevenBellovinandRosarioGennaro, selected 30 for presentation at the conference. The Best Student Paper Award was given to Liang Xie and Hui Song for their paper "On the E?ectiveness of Internal Patch Dissemination Against File-Sharing Worms" (co-authored with Sencun Zhu). These proceedings consist of revised versions of the presented papers. The revisions werenot reviewed.The authors bear full responsibility for the contents of their papers. Thereweremany submissionsof goodquality, and consequentlythe selection process was challenging and very competitive. Indeed, a number of good papers were not accepted due to lack of space in the program. The main considerations in selecting the program were conceptual and technical innovation and quality of presentation. As re?ected in the Call for Papers, an attempt was made to solicit and publish papers suggesting novel paradigms, original directions, or non-traditional perspectives.
