Thequestion Streamciphers:deadoralive? wasposedbyAdiShamir.Intended to provokedebate,the questioncouldnot havebeen better, ormorestarkly,put. However,itwasnotShamir sintentiontosuggestthatstreamciphersthemselves were obsolete; rather he was questioning whether stream ciphers of a dedicated designwererelevantnowthattheAESispervasivelydeployedandcanbeusedas a perfectly acceptablestreamcipher. To explore this question the eSTREAM Project was launched in 2004, part of the EU-sponsored ECRYPT Framework VI Network of Excellence. The goal of the project was to encourage academia and industry to consider the dead stream cipher and to explore what could be achieved with a dedicated design. Now, after several years of hard work, the project has come to a close and the 16 ciphers in the ?nal phase of eSTREAM are the subject of this book. The designers of all the ?nalist ciphers are to be congratulated. Regardless of whether a particular algorithm appears in the ?nal portfolio, in reaching the third phase of eSTREAM all the algorithms constitute a signi?cant milestone in the development of stream ciphers. However, in addition to thanking all designers, implementers, and crypt- alysts who participated in eSTREAM, this is a ?tting place to o?er thanks to some speci?c individuals.

Summary
This state-of-the-art survey presents the outcome of the eSTREAM Project, which was launched in 2004 as part of ECRYPT, the European Network of Excellence in Cryptology (EU Framework VI). The goal of eSTREAM was to promote the design of new stream ciphers with a particular emphasis on algorithms that would be either very fast in software or very resource-efficient in hardware. Algorithm designers were invited to submit new stream cipher proposals to eSTREAM, and 34 candidates were proposed from around the world. Over the following years the submissions were assessed with regard to both security and practicality by the cryptographic community, and the results were presented at major conferences and specialized workshops dedicated to the state of the art of stream ciphers. This volume describes the most successful of the submitted designs and, over 16 chapters, provides full specifications of the ciphers that reached the final phase of the eSTREAM project. The book is rounded off by two implementation surveys covering both the software- and the hardware-oriented finalists.
