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.

History of cryptography Cryptanalysis Outline of cryptography.

Phase 1 included a general analysis of all submissions with the purpose of selecting a subset of the submitted designs for further scrutiny.

Retrieved 23 March RC4 block ciphers in stream mode ChaCha. Additionally a number of algorithms for each profile are accepted as Phase 2 algorithms, meaning that they are still valid as eSTREAM candidates.

Both profiles contain an “A” subcategory 1A and 2A with ciphers that also estreaam authentication in addition to encryption. This cipher was in the original portfolio, but was removed in revision 1, published in September From Wikipedia, the free encyclopedia.

Notes on the ECRYPT Stream Cipher project (eSTREAM)

The selected Profile 1 algorithms were: The framework was then used to benchmark the candidates on a wide variety of systems. 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 project was divided into separate phases and the project goal was to find algorithms suitable for different application profiles. Activities in Phase 1 included a large amount of analysis and presentations of analysis results as well as discussion.

The call for primitives was first issued in November The selected Projdct 2 algorithms were: Submissions in Profile 1 were only accepted if they demonstrated software performance superior to AES in counter mode.

This article relies too much on references to primary sources. The designs were scrutinized based on criteria of security, performance with respect to the block cipher AES — a US Government approved standard, estreaj well as the other candidatessimplicity and flexibility, justification and supporting analysis, and clarity and completeness of the documentation.

The project also developed a framework for testing the performance of the candidates. The Focus 2 candidates will be re-classified every six months.
