Project to identify new stream ciphers for widespread adoption

eSTREAM is a project to "identify new stream ciphers suitable for widespread adoption", organised by the EU ECRYPT network. It was set up as a result of the failure of all six stream ciphers submitted to the NESSIE project. The call for primitives was first issued in November 2004. The project was completed in April 2008. The project was divided into separate phases and the project goal was to find algorithms suitable for different application profiles.

Phase 1 included a general analysis of all submissions with the purpose of selecting a subset of the submitted designs for further scrutiny. The designs were scrutinized based on criteria of security, performance (with respect to the block cipher AES—a US Government approved standard, as well as the other candidates), simplicity and flexibility, justification and supporting analysis, and clarity and completeness of the documentation. Submissions in Profile 1 were only accepted if they demonstrated software performance superior to AES 128 in counter mode. Activities in Phase 1 included a large amount of analysis and presentations of analysis results as well as discussion. The project also developed a framework for testing the performance of the candidates. The framework was then used to benchmark the candidates on a wide variety of systems. On 27 March 2006, the eSTREAM project officially announced the end of Phase 1.

On 1 August 2006, Phase 2 was officially started. For each of the profiles, a number of algorithms has been selected to be Focus Phase 2 algorithms. These are designs that eSTREAM finds of particular interest and encourages more cryptanalysis and performance evaluation on these algorithms. Additionally a number of algorithms for each profile are accepted as Phase 2 algorithms, meaning that they are still valid as eSTREAM candidates. The Focus 2 candidates will be re classified every six months.
