INDOCRYPT 2001, the Second Annual Crypto Conference, is proof of the s- ni?cant amount of enthusiasm generated among Indian as well as International crypto communities. INDOCRYPT 2001 was organized by the Indian Institute of Technology, Madras and the Institute of Mathematical Sciences, also located in Madras (now Chennai). This event was enthusiastically co-sponsored by eAl- traz ConsultingPrivate Ltd, Chennai, Odyssey Technologies Ltd, Chennai, and Shanmuga Arts Science Technology and Research Academy (SASTRA), Th- javur. The Program Committee Co-chair, Prof.C.Pandu Rangan was responsible for local organization and registration. The Program Committee considered 77 papers and selected 31 papers for presentation. These papers were selected on the basis of perceived originality, quality, and relevance to the ?eld of cryptography. The proceedings include the revised version of the accepted papers. Revisions were not checked as to their contents and authors bear full responsibility for the contents of their submissions. The selection of papers is a very challengingand demandingtask. We wish to thank the Program Committee members who did an excellent job in reviewing the submissions in spite of severe time constraints imposed by the tight p- cessingschedule. Each submission was reviewed by at least three referees (only a few by two). The Program Committee was ably assisted by a large number of reviewers in their area of expertise. The list of reviewers has been provided separately. Our thanks go to all of them.

th This volume contains the proceedings of the 19 FST&TCS conference (Foundations of Software Technology and Theoretical Computer Science), - ganized under the auspices of the Indian Association for Research in Computing Science (http://www. imsc. ernet. in/~iarcs). This year's conference attracted 84 submissions from as many as 25 dieren t countries. Each submission was reviewed by at least three independent referees. th After a week-long e-mail discussion, the program committee met on the 7 th and 8 of August, 1999, in Chennai and selected 30 papers for inclusion in the conference program. We thank the program committee members and the reviewers for their sincere eorts. We are fortunate to have ve invited speakers this year, providing for a very attractive program: Mart n Abadi (Bell Labs - Lucent Technologies, Palo Alto, USA), Lila Kari (Univ. Western Ontario, Canada), Jean-Jacques L evy (INRIA, Paris,France),Micha Sharir, (Univ. TelAviv,Israel),andSeinosuke Toda (IEC, Tokyo,Japan). Moreover,theconferenceisprecededbyatwo-dayworkshop(- cember 11{12, 1999) on Data Structures and succeeded by a two-day workshop (December 16-17, 1999) on Foundations of Mobile Computation.The conference also features two joint sessions with the International Symposium on - tomata, Algorithms and Computation (December 16{18, 1999, Chennai): Monika Henzinger (Compaq Systems Research, Palo Alto, USA) is presenting a tutorial on Web algorithmics as the last event of FST&TCS and Kurt Mehlhorn (Max-Planck-Institut, Saarbru ..cken, Germany) is giving a talk on algorithm - gineering as the rst event of ISAAC.

th This volume contains the proceedings of the 10 ISAAC conference (Tenth - nual International Symposium on Algorithms And Computation) held in Ch- nai, India. This year's conference attracted 71 submissions from as many as 17 di erent countries. Each submission was reviewed by at least three independent referees. After a week-long e-mail discussion, the program committee agreed to include 40 papers in the conference program. The high acceptance rate is clearly an indication of the quality of the papers received. We thank the program c- mittee members and the reviewers for their sincere e orts. We were fortunate to have three invited speakers this year, providing for a very attractive program: Kurt Mehlhorn (MPI, Saarbruck .. en, Germany), Eva T- dos (Cornell University, U.S.A.), and Kokichi Sugihara (Univ. of Tokyo, Japan). Moreover, the conference was preceded by a tutorial on a cutting-edge area, Web Algorithmics by Monika Henzinger (Compaq Systems Research Center, Palo Alto, U.S.A.) as a joint event with FST&TCS 99 (Foundations of Software Te- nology and Theoretical Computer Science, December 13-15, 1999, Chennai).Asa post conference event, a two-day workshop on Approximate Algorithms by R.Ravi (CMU, U.S.A.) and Naveen Garg (IIT, Delhi) was organized. We thank all the in- ted speakers and special event speakers for agreeing to participate in ISAAC'99.

This book constitutes the refereed proceedings of the 8th International Conference on Cryptology in India, INDOCRYPT 2007, held in Chennai, India, in December 2007. The papers and three invited lectures were carefully reviewed and selected. The papers are organized in topical sections on hashing, elliptic curve, cryptoanalysis, information theoretic security, elliptic curve cryptography, signature, side channel attack, symmetric cryptosystem, asymmetric cryptosystem, and short papers.
