The Program Committee, consisting of 21 members, considered 120 papers and selected 32 for presentation. In addition, Ross Anderson kindly agreed to chairthetraditionalrumpsessionforinformalshortpresentationsofnewresults. These proceedings include the revisedversionsof the 32 papers accepted by the Program Committee. These papers were selected on the basis of originality, quality, and relevance to cryptography. As a result, they should give a proper picture of how the (cid:12)eld is evolving. Revisions were not checkedand the authors bear full responsibility for the contents of their papers. Theselectionofpaperswasadi(cid:14)cultandchallengingtask.Eachsubmission was refereed by at least three reviewers and most had four reports or more. I wish to thank the program committee members, who did an excellent job. In addition, I gratefully acknowledge the help of a large number of colleagues who reviewedsubmissionsintheirareasofexpertise.Theyare:MichelAbdalla,Josh Benaloh,CharlesBennett,SimonBlackburn,MattBlaze,ChristianCachin,Jan Camenisch, Ran Canetti, Benny Chor, Galdi Clemente, Jean-S(cid:19)ebastien Coron, Paolo D’Arco, Anand Desai, Uri Feige, Marc Fischlin, Roger Fischlin, Matt Franklin, Steven Galbraith, Rosario Gennaro, Pierre Girard, Dieter Gollmann, Shai Halevi, Helena Handschuh, Yuval Ishai, Markus Jakobsson, Mike Just, Ted Krovetz, Kaoru Kurosawa, Eyal Kushilevitz, Keith Martin, Barbara Ma- succi, Johannes Merkle, Daniele Micciancio, Victor S.

I also wish to thank my PhD students Phong Nguyen, Thomas Pornin, and Guillaume Poupard, who helped me a great deal at various steps of the whole process. Their computer skills and the time and e(cid:11)ort they invested were a crucial ingredient of my ability to run the programcommittee. Thomas ran the electronic submission phase and was able to print all postscript (cid:12)les, including those produced by non-standard word processors. Guillaume opened a private VI Preface FTP server and Web site for PC members, and Phong did the editing work, both in paper and in electronic form. I hope I did not distract them too much from their research,but they were kind enough to tell me they had learnt a lot. Thanks also to Joelle Isnard and Nadine Riou, who organized the PC meeting in Paris. Following the example of CRYPTO ’98, EUROCRYPT ’99 was the (cid:12)rst of the Eurocrypt series with electronic submissions. The electronic submission optionwasaclearchoiceforalmostallauthors,withonly5%ofthe paperssub- mitted by regular mail. I believe that the time has come to make e-submission mandatory,but it will be the choice of future Crypto and EurocryptPC chairs. I wishtothank JoeKilian,whoforwardedus the electronicsubmissionsoftware used for CRYPTO ’98 and helped us run it. This software was originally de- veloped by ACM’s SIGACT group and I thank the ACM for allowing us to use their system. Finally,Iwishtothanktheallauthorswhosubmittedpapersformakingthis conferencepossiblebycreatingthescienti(cid:12)cmaterial,andespeciallytheauthors ofacceptedpapers.Iwouldalsoliketothankthe publisher,Springer-Verlag,for working within a tight schedule in order to produce these proceedings in due time.
