The 1st International Conference on "Applied Cryptography and Network Security" (ACNS 2003) was sponsored and organized by ICISA (International Communications and Information Security Association), in cooperation with MiAn Pte. Ltd. and the Kunming government. It was held in Kunming, China in October 2003. The conference proceedings was published as Volume 2846 of the Lecture Notes in Computer Science (LNCS) series of Springer-Verlag.

The conference received 191 submissions, from 24 countries and regions; 32 of these papers were accepted, representing 15 countries and regions (acceptance rate of 16.75%). In this volume you will find the revised versions of the accepted papers that were presented at the conference. In addition to the main track of presentations of accepted papers, an additional track was held in the conference where presentations of an industrial and technical nature were given. These presentations were also carefully selected from a large set of presentation proposals.

This new international conference series is the result of the vision of Dr. Yongfei Han. The conference concentrates on current developments that advance the areas of applied cryptography and its application to systems and network security. The goal is to represent both academic research works and developments in industrial and technical frontiers. We thank Dr. Han for initiating this conference and for serving as its General Chair.

Many people and organizations helped in making the conference a reality. We thank the conference sponsors: the Kunming government, MiAn Pte. Ltd., and ICISA. We greatly thank the organizing committee members for taking care of the registration, logistics, and local arrangements. It is due to their hard work that the conference was possible. We also wish to thank Springer and Mr. Alfred Hofmann and his staff for the advice regarding the publication of the proceedings as a volume of LNCS. Our deepest thanks go to the program committee members for their hard work in reviewing papers. We also wish to thank the external reviewers who assisted the program committee members.

Last, but not least, special thanks are due to all the authors who submitted papers and to the conference participants from all over the world. We are very grateful for their support, which was especially important in these difficult times when the SARS outbreak impacted many countries, especially China. It is in such challenging times for humanity that the strength and resolve of our community is tested: the fact that we were able to attract many papers and prepare and organize this conference is testament to the determination and dedication of the cryptography and security research community worldwide.

• 2nd ACNS  –  Yellow Mountain, China, June 8-11, 2004

The 2nd International Conference on Applied Cryptography and Network Security (ACNS 2004) was sponsored and organized by ICISA (the International Communications and Information Security Association). It was held in Yellow Mountain, China, June 8-11, 2004. The conference proceedings, representing papers from the academic track, are published in this volume of the Lecture Notes in Computer Science (LNCS) of Springer-Verlag.

The area of research that ACNS covers has been gaining importance in recent years due to the development of the Internet, which, in turn, implies global exposure of computing resources. Many fields of research were covered by the program of this track, presented in this proceedings volume. We feel that the papers herein indeed reflect the state of the art in security and cryptography research, worldwide.

The program committee of the conference received a total of 297 submissions from all over the world, of which 36 submissions were selected for presentation during the academic track. In addition to this track, the conference also hosted a technical/industrial track of presentations that were carefully selected as well. All submissions were reviewed by experts in the relevant areas.

Starting from the first ACNS conference last year, ACNS has given best paper awards. Last year the best student paper award went to a paper that turned out to be the only paper written by a single student for ACNS 2003. It was Kwong H. Yung who got the award for his paper entitled "Using Feedback to Improve Masquerade Detection". Continuing the "best paper tradition" this year, the committee decided to select two student papers among the many high-quality papers that were accepted for this conference, and to give them best student paper awards. These papers are: "Security Measurements of Steganographic Systems" by Weiming Zhang and Shiqu Li, and "Evaluating Security of Voting Schemes in the Universal Composability Framework" by Jens Groth. Both papers appear in this proceedings volume, and we would like to congratulate the recipients for their achievements.

Many people and organizations helped in making the conference a reality. We would like to take this opportunity to thank the program committee members and the external experts for their invaluable help in producing the conference’s program. We also wish to thank Thomas Herlea of KU Leuven for his extraordinary efforts in helping us to manage the submissions and for taking care of all the technical aspects of the review process. Thomas, single-handedly, served as the technical support committee of this conference! We extend our thanks also to the general chair Jianying Zhou (who also served as publication chair and helped in many other ways), the chairs of the technical/industrial track (Yongfei Han and Peter Landrock), the local organizers, who worked hard to assure that the conference took place, and the publicity chairs. We also thank the various sponsoring companies and government bodies. Finally, we would like to thank all the authors who submitted papers to the conference.

• 5th ACNS  –  Zhuhai, China, June 5-8, 2007
  

The 5th International Conference on Applied Cryptography and Network Security (ACNS 2007) was held in Zhuhai, China, June 5-8, 2007. This volume contains papers that were accepted to the academic track of the conference.

The conference received an astounding number of submissions this year, which made the review process a challenging and demanding task. We are indebted to the members of the Program Committee and the external reviewers for all their hard work. The committee accepted 31 papers from roughly 260 submissions. These proceedings contain revised versions of the accepted papers. While revisions are expected to take the referees' comments into account, this was not enforced and the authors bear full responsibility for the content of their papers.

In addition to the academic track, the conference hosted a non-archival industrial track whose papers were also carefully selected from among the submissions.

Shai Halevi deserves the community's gratitude for writing his web submission and review software, which we used for this conference. On a more personal level, we would like to extend our own deepest thanks to Shai for not only writing his software, but for installing and maintaining the submission server for this conference. Thanks go also to the International Association for Cryptologic Research (IACR) for agreeing to host the server.

It is our pleasure to thank the General Chair Yongfei Han, the Publicity Chair Jianying Zhou, and the Chair of the Organizing Committee Li Nan for their help and support in putting this conference together. Without their help, this conference would not have been possible. Finally, we are grateful to ONETS and Zhuhai College, Jilin University, for sponsoring the conference.

• 6th ACNS  –  New York, USA, June 3-6, 2008
  

ACNS 2008, the 6th International Conference on Applied Cryptography and Network Security, was held in New York, New York, June 3-6, 2008, at Columbia University. ACNS 2008 was organized in cooperation with the International Association for Cryptologic Research (IACR) and the Department of Computer Science at Columbia University. The General Chairs of the conference were Angelos Keromytis and Moti Yung.

The conference received 131 submissions, of which the Program Committee, chaired by Steven Bellovin and Rosario Gennaro, 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 Effectiveness 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 were not reviewed. The authors bear full responsibility for the contents of their papers.

There were many submissions of good quality, and consequently the 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 reflected in the Call for Papers, an attempt was made to solicit and publish papers suggesting novel paradigms, original directions, or non-traditional perspectives.

We would like to extend our heartfelt thanks to the ProgramCommittee members, who dedicated so much time and effort to provide a thorough and in-depth review of the submissions, with high standards of professional integrity. We also thank the many external reviewers who assisted the Program Committee in its work. Most importantly, we thank the authors of submitted papers for their contributions; without these papers, after all, there would be no ACNS conference.

A special thanks is due to Shai Halevi for writing the software that greatly facilitated the committee work, and for his responsiveness in answering all our questions.

We are grateful to Jianying Zhou who, as Publicity Chair, relentlessy advertised the conference, to Angelika Zavou for her timely maintenance of the conference website and to Sophie Majewski for helping with the local arrangements.

Finally, we appreciate the assistance provided by the Springer LNCS editorial staff in assembling these proceedings.

These proceedings contain the papers selected for presentation at the 10th International Conference on Applied Cryptography and Network Security (ACNS 2012), held during June 26-29, 2012, in Singapore. The conference was organized by iTwin, sponsored by AdNovum, and supported by Infocomm Development Authority of Singapore (IDA).

In response to the call for papers, 192 papers from 38 countries were submitted to the conference. These papers were evaluated on the basis of their significance, novelty, technical quality, and practical impact. Reviewing was “double-blind”: the identities of reviewers were not revealed to the authors of the papers and author identities were not revealed to the reviewers. The Program Committee meeting was held electronically, yielding intensive discussion over a period of two weeks. Of the papers submitted, 33 were selected for presentation at the conference and inclusion in this Springer volume (LNCS 7341), giving an acceptance rate lower than 18%.

Besides the technical program composed of the papers collated in the proceedings, the conference included a non-archival industrial track. The conference was also featured with 3 keynote speeches, by Moti Yung (co-founder of ACNS) entitled “Applied Cryptography and Network Security - 10 years in the past and 10 years in the future”, by Peng Ning entitled “Cloud Computing Infrastructure Security”, and by Hongjun Wu entitled “JH in the NIST Hash Function Competition”, respectively.

There is a long list of people who volunteered their time and energy to put together the conference and who deserve special thanks. Thanks to the Program Committee members and the external reviewers, for all their hard work in the paper evaluation. Owing to the large number of submissions, the Program Committee members were required to work hard in a short time frame, and we are very thankful to them for the commitment they showed with their active participation in the electronic discussion.

We are also very grateful to all those people whose work ensured a smooth organization process: Xinyi Huang and Giovanni Livraga, Publicity Chairs, for their work in ensuring the wide distribution of the call for papers and participation; Shen-Tat Goh, Organizing Chair, as well as Lux Anantharaman and Kal Takru for taking care of the local organization and Ying Qiu for managing the conference website and EasyChair system.

• 11th ACNS  –  Banff, Canada, June 25-28, 2013
  

ACNS 2013, the 11th International Conference on Applied Cryptography and Network Security, was held during June 25-28 at Banff, Alberta, Canada.

We received 150 submissions of which 33 were accepted as regular papers (22% acceptance rate), and two as short papers. These proceedings contain the revised versions of all the papers. There were three invited talks. Ahmad-Reza Sadeghi, professor of Computer Science at Technische Universität Darmstadt, gave a talk entitled “Selected Topics in Mobile Security and Trusted Computing”. Bryan Parno from Microsoft Research Redmond, gave a talk on “Bootstrapping Cloud Security”, and Francois Theberge, research mathematician with the Tutte Institute for Mathematics and Computing spoke about “Ensemble Clustering for Graphs-Based Data”.

The Program Committee (PC) consisted of 35 members with diverse research interest and experience. Papers were reviewed double-blind, with each paper assigned to three reviewers. During the discussion phase, when necessary, extra reviews were solicited. We ensured that all papers received fair and objective evaluation by experts and also a broader group of PC members, with particular attention paid to highlighting strengths and weaknesses of papers. The final decisions were made based on the reviews and discussion. The task of paper selection was especially challenging given the high number of strong submissions. In the end, a sizable number of strong papers could not be included in the program owing to lack of space.

We would like to sincerely thank authors of all submissions – those whose papers made it into the program and those whose papers did not. We, and the PC as a whole, were impressed by the quality of submissions contributed from all around the world. Although this made the task of selecting the final list very challenging, it gave us the opportunity to have a strong and diverse program. We would like to extend our sincere gratitude to the Program Committee.We were very fortunate that so many talented people put such an inordinate amount of time to write reviews and actively participate in discussions for nearly three weeks. They responded to our requests for extra reviews, opinions, comments, comparisons, and inputs. We were impressed by the knowledge, dedication, and integrity of our PC. We also would like to thank many external reviewers, some contacted by us directly and some through PC members, who significantly contributed to the comprehensive evaluation of papers. A list of PC members and external reviewers appears after this note.

We would like to thank Mahabir Jhanwar, the Publicity Chair, for working closely with us throughout the whole process, providing the much needed support in every step. We would also like to thank Tongjie Zhang for handling our social media presence, Coral Burns for her work on the ACNS website, Deb Angus for logistical and administrative support, Camille Sinanan for her help with the local organization and financial administration, and, finally, Hadi Ahmadi and numerous student volunteers who helped us with the successful organization of the program.

We benefited from advice and feedback from Moti Yung and Jianying Zhou, the ACNS Steering Committee. Alfred Hofmann and his colleagues at Springer provided a meticulous service for the timely production of this volume.

We would like to thank Microsoft Research, the Pacific Institute for Mathematical Sciences (PIMS), Alberta Innovates Technology Future (AITF), and the University of Calgary for their generous support. We also gratefully acknowledge our partnership with the Tutte Institute for Mathematics and Computing (TIMC), in contributing to the success of this conference.

ACNS 2018, the 16th International Conference on Applied Cryptography and Network Security, was held during July 2–4, 2018, at KU Leuven, Belgium. The local organization was in the capable hands of the COSIC team at KU Leuven and we are deeply indebted to them for their support and smooth collaboration.

We received 173 paper submissions, out of which 36 were accepted, resulting in an acceptance rate of 20%. These proceedings contain revised versions of all the papers. The invited keynotes were delivered by Gilles Barthe, who spoke on formal verification of side-channel resistance and Haya Shulman who shared with the audience her perspective on RPKI’s Deployment and Security of BGP.

The Program Committee consisted of 52 members with diverse backgrounds and broad research interests. The review process was double-blind. Each paper received at least three reviews; for submissions by Program Committee members, this was increased to five. During the discussion phase, additional reviews were solicited when necessary. An intensive discussion was held to clarify issues and to converge toward decisions. The selection of the program was challenging; in the end some high-quality papers had to be rejected owing to lack of space. The committee decided to give the Best Student Paper Award to the paper “Non-interactive zaps of knowledge” by Georg Fuchsbauer and Michele Orrù.

We would like to sincerely thank the authors of all submissions for contributing high-quality submissions and giving us the opportunity to compile a strong and diverse program. We know that the Program Committee’s decisions can be very disappointing, especially rejections of good papers that did not find a slot in the sparse number of accepted papers.

Special thanks go to the Program Committee members; we value their hard work and dedication to write careful and detailed reviews and to engage in interesting discussions. A few Program Committee members, whom we asked to serve as shepherds, spent additional time in order to help the authors improve their works. More than 160 external reviewers contributed to the review process; we would like to thank them for their efforts.

Finally, we thank everyone else — speakers and session chairs — for their contribution to the program of ACNS 2018. We would also like to thank the sponsors for their generous support.

We are pleased to present the proceedings of the 17th International Conference on Applied Cryptography and Network Security (ACNS 2019) held during June 5–7 2019, in Bogotá, Colombia. The local organization was in the capable hands of Professors Valérie Gauthier-Umaña from Universidad del Rosario, Colombia, and Martín Ochoa, Universidad del Rosario and Cyxtera Technologies, and we are deeply indebted to them for their generous support and leadership to ensure the success of the conference.

We received 111 submissions from all over the world. This year’s Program Committee (PC) consisted of 56 members with diverse background and broad research interests. The review process was double-blind and rigorous. The selection of the program was challenging; in the end some high-quality papers had to be rejected owing to lack of space. After the review process concluded, 29 papers were accepted to be presented at the conference and included in the proceedings, representing an acceptance rate of about 26%.

Among those papers, ten were co-authored and presented by full-time students. From this subset, we awarded two Best Student Paper Awards, to Matthias J. Kannwischer (co-authored with Joost Rijneveld and Peter Schwabe) for the paper “Faster Multiplication in Z_2^m [x] on Cortex-M4 to Speed up NIST PQC Candidates and Zhengzhong Jin (co-authored with Yunlei Zhao) for the work “Practical Key Establishment from Lattice.” These papers received very positive comments by the reviewers and we appreciated their theoretical and practical contributions in the post-quantum cryptography field. To them also goes a monetary prize of 500 euro each, generously sponsored by Springer.

This year we had two outstanding keynote talks: “Toward Secure High-Performance Computer Architectures” presented by Prof. Srini Devadas, MIT, and “Foundational Aspects of Blockchain Protocols” by Prof. Juan Garay, Texas A&M University. To Srini and Juan, our deepest gratitude for their excellent presentations.

We had a strong program along with a workshop track in parallel with the main event, providing a forum to address specific topics at the forefront of cybersecurity research. The papers presented at those sessions will be published in separate proceedings.

ACNS 2019 was made possible by the joint efforts of many individuals and organizations. We sincerely thank the authors of all submissions. We are grateful to all the PC members for their great effort in reading, commenting, debating, and finally selecting the papers. We also thank all the external reviewers for assisting the PC intheir particular areas of expertise. Finally, we thank everyone else, speakers and session chairs, for their contribution to the program of ACNS 2019.

We would also like to thank the sponsors for their generous support: Universidad del Rosario, the Fellows program from ICETEX, Cyxtera Technologies, Google and
Springer.

We are pleased to present the proceedings of the 18th International Conference on Applied Cryptography and Network Security (ACNS 2020).

ACNS 2020 was planned to be held in Rome, Italy, during June 22–25, 2020. Due to the unexpected covid crisis, we first postponed the conference to October 19–22, 2020, but ended up deciding for the safety of all participants to have a virtual conference. The local organization was in the capable hands of Emiliano Casalicchio and Angelo Spognardi (Sapienza University of Rome, Italy) and Giuseppe Bernieri (University of Padua, Italy) as general co-chairs, and Massimo Bernaschi (CNR, Italy) as organizing chair. We are deeply indebted to them for their tireless work to ensure the success of the conference even in such complex conditions.

For the first time, ACNS had two rounds of submission cycles, with deadlines in September 2019 and January 2020, respectively. We received a total of 214 submissions in two rounds from 43 countries. This year’s Program Committee (PC) consisted of 77 members with diverse backgrounds and broad research interests. The review process was double-blind and rigorous, and papers were evaluated on the basis of research significance, novelty, and technical quality. Some papers submitted in the first round received a decision of major revision. The revised version of those papers were further evaluated in the second round and most of them were accepted. After the review process concluded, a total of 46 papers were accepted to be presented at the conference and included in the proceedings, representing an acceptance rate of around 21%.

Among those papers, 30 were co-authored and presented by full-time students. From this subset, we awarded the Best Student Paper Award to Joyanta Debnath (co-authored with Sze Yiu Chau and Omar Chowdhury) for the paper “When TLS Meets Proxy on Mobile.” The reviewers particularly appreciated its practical contributions in the proxybased browsers field and the comments were positive overall. The monetary prize of 1,000 euro was generously sponsored by Springer.

We had a rich program including the satellite workshops in parallel with the main event, providing a forum to address specific topics at the forefront of cybersecurity research. The papers presented at those workshops were published in separate proceedings.

This year we had two outstanding keynote talks: “Global communication guarantees in the presence of adversaries” presented by Prof. Adrian Perrig, ETH Zurich, Switzerland, and “Is AI taking over the world? No, but it’s making it less private” by Prof. Giuseppe Ateniese, Stevens Institute of Technology, USA. To them, our heartfelt gratitude for their outstanding presentations.

In this very unusual year, the conference was made possible by the untiring joint efforts of many individuals and organizations. We are grateful to all the authors for their submissions. We sincerely appreciate the outstanding work of all the PC members and the external reviewers, who selected the papers after reading, commenting, and debating them. Finally, we would thank all the people who volunteered their time and energy to put together the conference, speakers and session chairs, and everyone who contributed to the success of the conference.

Last, but certainly not least, we are very grateful to Sapienza University of Rome for sponsoring the conference, and Springer, for their help in assembling these proceedings.

• 21st ACNS  –  Kyoto, Japan, June 19-22, 2023
  

ACNS 2023, the 21st International Conference on Applied Cryptography and Network Security, was held in Kyoto, Japan on June 19–22, 2023. The conference covered all technical aspects of applied cryptography, cyber security (including network and computer security) and privacy, representing both academic research works as well as developments in industrial and technical frontiers.

We received a total of 263 submissions from all over the world, among which the Program Committee (PC) selected 53 papers for publication in the proceedings of the conference. The two program chairs were supported by a PC consisting of 74 leading experts in all aspects of applied cryptography and security. Each submission received around 4 reviews from the committee. Strong conflict of interest rules ensured that papers were not handled by PC members with a close personal or professional relationship with the authors. The two program chairs were not allowed to submit a paper. There were approximately 180 external reviewers, whose input was critical to the selection of papers.

The review process was conducted using double-blind peer review. The conference had two possible submission deadlines, in September and January respectively. The authors of some submissions rejected from the September deadline, considered promising nonetheless, were encouraged to resubmit to the January deadline after appropriate revisions. Most of these revised papers were eventually accepted.

Alongside the presentations of the accepted papers, the program of ACNS 2023 featured two excellent invited talks by Shuichi Katsumata and Michalis Polychronakis.

The two volumes of the conference proceedings contain the revised versions of the 53 papers that were selected, together with the abstracts of the two invited talks. The final revised versions of papers were not reviewed again and the authors are responsible for their contents.

Following a long tradition, ACNS gives a best student paper award to encourage promising students to publish their best results at the conference. This year, the award was shared between two papers, one on the applied cryptography side and another on the security and systems side. The full-time students who received the awards were Agathe Cheriere for her paper “BIKE Key-Recovery: Combining Power Consumption Analysis and Information-Set Decoding” (co-authored with Nicolas Aragon, Tania Richmond and Benoît Gérard) and Ping-Lun Wang and Kai-Hsiang Chou for their paper “Capturing Antique Browsers in Modern Devices: A Security Analysis of Captive Portal Mini-Browsers” (co-authored with Shou-Ching Hsiao, Ann Tene Low, Tiffany Hyun-Jin Kim and Hsu-Chun Hsiao). The recipients shared a monetary prize of 1,500 EUR generously sponsored by Springer.

Many people contributed to the success of ACNS 2023. We would like to thank the authors for submitting their research results to the conference. We are very grateful to the PC members and external reviewers for contributing their knowledge and expertise, and for the tremendous amount of work involved in reviewing papers and contributing to the discussions. We are greatly indebted to Chunhua Su and Kazumasa Omote, the General Chairs, for their efforts and overall organization. We thank the steering committee for their direction and valuable advice throughout the preparation of the conference. We also thank the team at Springer for handling the publication of these conference proceedings, as well as Siyuan Tang for helping with the preparation of the proceedings volumes.
