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 . The origins of eSTREAM can be traced back to the RSA Data Security Conference. There, as part of the Cryptographer’s Panel, Adi Shamir made some . eSTREAM: the ECRYPT Stream Cipher Project. Requirements. Submissions to eSTREAM were required to fit into at least one of the following two profiles.

The framework was then used to benchmark the candidates on a wide variety of systems. Retrieved from ” https: The Focus 2 candidates will be re-classified every six months. Cryptography contests Research projects Stream ciphers.

Submissions in Profile 1 were only accepted if they demonstrated software performance superior to AES in counter mode. On 1 AugustPhase 2 was officially started.

This article relies too much on references to primary sources.

The project was divided into separate phases and the project goal was to find algorithms suitable for different application profiles. Archived from the original pdf on 18 October Additionally a number of algorithms for each profile are accepted as Phase 2 algorithms, meaning that they are still valid as eSTREAM candidates.


History of cryptography Cryptanalysis Outline of cryptography. Activities in Phase 1 included a large amount of analysis and presentations of analysis results as well as discussion.

Cryptographic competitions

The selected Profile 2 algorithms were: Views Read Edit View history. Retrieved 23 March In Phase 3 none of the ciphers providing authentication are being considered The NLS cipher had authentication removed from it to improve its performance.

The selected Profile 1 algorithms were: These are designs that eSTREAM finds of particular interest and encourages more cryptanalysis and performance evaluation proiect these algorithms. Phase 1 included a general analysis of all submissions with the purpose of selecting a subset of the submitted designs for further scrutiny. The project was completed in April Please improve this by adding secondary or tertiary sources.

The project also developed a framework for testing the performance of the candidates. Retrieved 2 April 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 porject candidatessimplicity and flexibility, justification and supporting analysis, and clarity and completeness of the documentation.

Both profiles contain an “A” subcategory 1A and 2A with ciphers that also provide authentication in addition to encryption. Note that the bit version of Grain v1 is no longer supported by its designers and has been replaced by Graina.
