ThesearetheproceedingsofCHES2002,theFourthWorkshoponCryptographic Hardware and Embedded Systems. After the ?rst two CHES Workshops held in Massachusetts, and the third held in Europe, this is the ?rst Workshop on the West Coast of the United States. There was a record number of submissions this year and in response the technical program was extended to 3 days. As is evident by the papers in these proceedings, there have been again many excellent submissions. Selecting the papers for this year’s CHES was not an easy task, and we regret that we could not accept many contributions due to the limited availability of time. There were 101 submissions this year, of which 39 were selected for presentation. We continue to observe a steady increase over previous years: 42 submissions at CHES ’99, 51 at CHES 2000, and 66 at CHES 2001. We interpret this as a continuing need for a workshop series that c- bines theory and practice for integrating strong security features into modern communicationsandcomputerapplications. Inadditiontothesubmittedcont- butions, Jean-Jacques Quisquater (UCL, Belgium), Sanjay Sarma (MIT, USA) and a panel of experts on hardware random number generation gave invited talks. As in the previous years, the focus of the Workshop is on all aspects of cr- tographic hardware and embedded system security. Of special interest were c- tributionsthatdescribenewmethodsfore?cienthardwareimplementationsand high-speed software for embedded systems, e. g. , smart cards, microprocessors, DSPs, etc. CHES also continues to be an important forum for new theoretical and practical ?ndings in the important and growing ?eld of side-channel attacks.

These are the proceedings of CHES 2003, the ?fth workshop on Cryptographic HardwareandEmbeddedSystems,heldinCologneonSeptember8-10,2003.As with every previous workshop, there was a record number of submissions despite themuchearlierdeadlineinthisyear'scallforpapers.Thisisaclearindication of the growing international importance of the scope of the conference and the relevance of the subject material to both industry and academia. The increasing competition for presenting at the conference has led to many excellent papers and a higher standard overall. From the 111 submissions, time constraintsmeantthatonly32couldbeaccepted.Theprogramcommitteewo- ed very hard to select the best. However, at the end of the review process there were a number of good papers - which it would like to have included but for which, sadly, there was insu?cient space. In addition to the accepted papers appearing in this volume, there were three invited presentations from Hans D- bertin (Ruhr-Universit. at Bochum, Germany), Adi Shamir (Weizmann Institute, Israel), and Frank Stajano (University of Cambridge, UK), and a panel d- cussion on the e?ectiveness of current hardware and software countermeasures against side channel leakage in embedded cryptosystems.

These are the pre-proceedings of CHES 2000, the second workshop on Cryp- graphicHardware andEmbedded Systems. The rst workshop, CHES'99, which was held at WPI in August 1999, was received quite enthusiastically by people in academia and industry who are interested in hardware and software imp- mentations of cryptography. We believe there has been a long-standing need for a workshop series combining theory and practice for integrating strong data - curity into modern communications and e-commerce applications. We are very glad that we had the opportunity to serve this purpose and to create the CHES workshop series. As is evident by the papers in these proceedings, there have been many excellentcontributions.Selectingthepapersforthisyear'sCHESwasnotaneasy task, and we regret that we had to reject several good papers due to the limited availability of time. There were 51 submitted contributions to CHES 2000, of which 25 were selected for presentation. This corresponds to a paper acceptance rate of 49% for this year, which is a decrease from the 64% acceptance rate for CHES'99.Allpaperswerereviewed.Inadditiontothecontributedpresentations, we have invited two speakers.As last year, the focus of the workshop is on all aspects of cryptographic hardware and embedded system design. Of special interest were contributions that describe new methods for e cient hardware implementations and hi- speed software for embedded systems, e.g., smart cards, microprocessors, DSPs, etc. In addition, there were again several very interesting and innovative - pers dealingwith cryptanalysis in practice, rangingfrom side-channel attacks to FPGA-based attack hardware.

These are the proceedings of CHES 2001, the third Workshop on Cryptographic Hardware and Embedded Systems. The ?rst two CHES Workshops were held in Massachusetts, and this was the ?rst Workshop to be held in Europe. There was a large number of submissions this year, and in response the technical program was extended to 2 1/2 days. As is evident by the papers in these proceedings, many excellent submissions were made. Selecting the papers for this year’s CHES was not an easy task, and weregretthatwehadtorejectseveralveryinterstingpapersduetotheac l kof time. There were 66 submitted contributions this year, of which 31, or 47%, were selected for presentation. If we look at the number of submitted papers at CHES ’99 (42 papers) and CHES 2001 (51 papers), we observe a steady increase. We interpret this as a continuing need for a workshop series which combines theory and practice for integrating strong security features into modern communications and computer applications. In addition to the submitted contributions, Ross Anderson from Cambridge University, UK, and Adi Shamir from The Weizmann Institute, Israel, gave invited talks.
