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.

Rabbit was the only one that had a patent pending during the eStream competition, but it was released into the public domain in October The call for primitives projetc first issued in November The selected Profile 2 algorithms were: For each of the profiles, a number of algorithms has been selected to be Focus Phase 2 algorithms.

The project was divided into separate phases and the project goal was to find algorithms suitable for different application profiles. 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.

Retrieved 23 March Both profiles contain an “A” subcategory 1A and 2A with estdeam that also provide authentication in addition to encryption.

These are all free for any use. RC4 block ciphers in stream mode ChaCha. The framework was then used to benchmark the candidates on a wide variety of systems. The project also developed a framework for testing the performance of the candidates.

eestream In Phase 3 none of the ciphers providing authentication are being considered The NLS esream had authentication removed from it to improve its performance. Retrieved 2 April Additionally a number of algorithms for each profile are accepted as Phase 2 algorithms, meaning that they are still valid as eSTREAM candidates.

Please improve this by adding secondary or tertiary sources. 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 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.
