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 call for primitives was first issued in November The project was completed in April The project was divided into separate phases and the project goal was to find algorithms suitable for different application profiles.

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

In Phase 3 none of the ciphers providing authentication are being considered Projetc NLS cipher had authentication removed from it to improve its performance. These are all free for any use.

Crypto competitions: eSTREAM: the ECRYPT Stream Cipher Project

Rabbit was the only one that had a patent pending during the eStream competition, but it was released into the public domain in October 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 eestream, performance with respect to the block cipher AES — a US Sstream approved standard, as well as the other candidatessimplicity esteeam 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 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.

Notes on the ECRYPT Stream Cipher project (eSTREAM)

The framework was then used to benchmark the candidates on a wide variety of systems. On 1 AugustPhase 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 projedt 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 estrsam. The Focus 2 candidates will be re-classified every six months.

Cryptographic competitions

The selected Profile 1 algorithms were: The selected Profile 2 algorithms were: Note that the bit version of Grain v1 is no longer supported by its designers and has been replaced by Graina.
