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.

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

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

Retrieved from ” https: The selected Profile 1 algorithms were: On 1 AugustPhase 2 was officially started. From Wikipedia, the free encyclopedia.


In Phase 3 none of the ciphers providing authentication are being considered The NLS cipher had authentication removed from it to improve its performance.

Symmetric-key algorithm Block cipher Stream cipher Public-key cryptography Cryptographic hash function Message authentication code Random numbers Steganography. The project was completed in April This article relies too much on references to primary sources. The Focus 2 esfream will be re-classified every six months.

This cipher was in the original portfolio, but was removed in revision 1, published in September The framework was then used to benchmark the candidates on a wide variety of systems. Additionally a number of algorithms for each profile are accepted as Phase 2 algorithms, meaning that they are still valid as eSTREAM candidates.

Eli Biham and Jennifer Seberry. 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 candidatessimplicity and flexibility, justification and supporting analysis, and clarity and completeness of the documentation. The project was divided into separate phases and the project goal projdct to find algorithms suitable for different application profiles.


Submissions in Profile 1 were only accepted if they demonstrated software performance superior to AES in counter mode.

These are designs that eSTREAM finds of particular interest and encourages more cryptanalysis and performance evaluation on these algorithms.

RC4 block ciphers in stream mode ChaCha. Both profiles contain an “A” subcategory 1A and 2A with ciphers that also provide authentication in addition to encryption.
