Preface
ASIACRYPT2002washeldinQueenstown,NewZealand,December1–5,2002.
The conference was organized by the International Association for Cryptologic
Research (IACR).
The program committee received 173 submissions from around the world,
from which 34 were selected for presentation. Each submission was reviewed by
at least three experts in the relevant research area.
Let me first thank all the authors, including those whose submissions were
not successful, for taking the time to prepare the submissions. Their dedication
andeffortsinadvancingresearchincryptographymadethisconferencepossible.
Selecting presentations from such a large number of submissions was an ex-
tremely difficult and challenging task. The program committee members, to-
gether with external referees, spent thousands of hours of their precious time
reviewing the submissions. At the completion of the selection process, the pro-
gramcommitteereceived875reviewreportsintotal.Inaddition,thecommittee
received several hundred comments during the three-week period of discussions.
Taking this opportunity, I would like to thank all the program committee
membersfortheirtimeanddedication.Withouttheirexpertiseinthestateofthe
art in cryptography and their willingness to serve the data security community,
the conference would not have had such a high-quality program. I would also
like to thank the numerous external referees for their invaluable assistance in
identifying the scientific and practical merits of the submissions.
Thequalityoftheprogramwasfurtherenhancedbytwodistinguishedkeynote
speeches delivered by Prof. Tsutomu Matsumoto from Yokohama National Uni-
versity in Japan, and Dr. Moti Yung from CertCo and Columbia University
in the USA. On behalf of the program committee, I would like to thank both
prominent pioneers in cryptography for their inspiring presentations.
ThanksalsogotothegeneralchairHankWolfefromtheUniversityofOtago
for successfully running the conference in such a beautiful town. It was a won-
derful experience for me to work with Hank.
The reviewing process benefited greatly from the advice of Bart Preneel and
Wim Moreau on handling the reviewing software. I appreciated Colin Boyd’s
assistance in editing the proceedings. My special thanks go to Lawrence Teo
who acted as my assistant during the entire period of setting up the website,
accepting, reviewing submissions, and editing the final proceedings. The year-
longprocesswouldnothaverunsosmoothlywithouthistirelesshelpandsuperb
technical skills in handling the software packages.
