The field of Cryptology witnessed a revolution in the late seventies. Since then it has been expanded into an important and exciting area of research. Over the last two decades, India neither participated actively nor did it contribute sig- nificantly towards the development in this field. However, recently a number of active research groups engaged in important research and developmental work have crystalized in different parts of India. As a result, their interaction with the international crypto community has become necessary. With this backdrop, it was proposed that a conference on cryptology - INDOCRYPT, be organized for the first time in India. The Indian Statistical Institute was instrumental in hosting this conference. INDOCRYPT has generated a large amount of enthu- siasm amongst the Indians as well as the International crypto communities. An INDOCRYPT steering committee has been formed and the committee has plans to make INDOCRYPT an annual event. For INDOCRYPT 2000, the program committee considered a total of 54 pa- pers and out of these 25 were selected for presentation. The conference program also included two invited lectures by Prof. Adi Shamir and Prof. Eli Biham. These proceedings include the revised versions of the 25 papers accepted by the program committee. These papers were selected from all the submissions based on originality, quality and relevance to the field of Cryptology. Revisions were not checked and the authors bear the full responsibility for the contents of the papers in these proceedings.

Pairing-based cryptography is at the very leading edge of the current wave in computer cryptography. That makes this book all the more relevant, being as it is the refereed proceedings of the First International Conference on Pairing-Based Cryptography, Pairing 2007, held in Tokyo, Japan in 2007. The 18 revised full papers presented together were carefully reviewed and selected from 86 submissions. The papers are organized in topical sections including those on applications, and certificateless public key encryption.

Even in the age of ubiquitous computing, the importance of the Internet will not change and we still need to solve conventional security issues. In addition, we need to deal with new issues such as security in the P2P environment, privacy issues in the use of smart cards, and RFID systems. Security and Privacy in the Age of Ubiquitous Computing addresses these issues and more by exploring a wide scope of topics. The volume presents a selection of papers from the proceedings of the 20th IFIP International Information Security Conference held from May 30 to June 1, 2005 in Chiba, Japan. Topics covered include cryptography applications, authentication, privacy and anonymity, DRM and content security, computer forensics, Internet and web security, security in sensor networks, intrusion detection, commercial and industrial security, authorization and access control, information warfare and critical protection infrastructure. These papers represent the most current research in information security, including research funded in part by DARPA and the National Science Foundation.

Asiacrypt'99 was held in Singapore on 14-18 November 1999. Asiacrypt is one of the major events in the cryptology research community. Asiacrypt'99, the ?fth annual Asiacrypt conference, was sponsored by the Asiacrypt Steering Comm- tee and the Centre for Systems Security of the National University of Singapore, and in cooperation with the International Association for Cryptology Research. As the Program Co-Chairs of Asiacrypt'99, we are extremely honored to or- nize this event, which showcases the state-of-the-art development of cryptology research at the conclusion of this millennium. This year, a total of 96 research papers were submitted to Asiacrypt'99. The portfolio of country of origin of submissions serves as a good indicator of the - ternational reputation of the conference. Countries from which submissions or- inated include: Australia, Belgium, China, Estonia, France, Germany, Greece, India, Iran, Japan, Korea, Norway, Russia, Saudi Arabia, Switzerland, Sin- pore, Spain, Taiwan, Thailand, The Netherlands, Turkey, Ukraine, UK, USA and Yugoslavia. Through a stringent refereeing process by the Program C- mittee, 31 papers of outstanding quality were accepted and are included in the conference proceedings. Accepted papers were authored by researchers from the following countries: Australia, Belgium, France, Germany, India, Japan, China, Singapore, Switzerland, Taiwan, The Netherlands, UK, and USA.
