This is the home page for eSTREAM, the ECRYPT Stream Cipher Project. This is a multi-year effort to identify new stream ciphers that might become suitable for widespread adoption. All information on the stream cipher project can be found on this site. A timetable of the project is to be found here. Some technical background on the project can be found here.

• SASC 2006 - Stream Ciphers Revisited

  On February 2-3, 2006, a special workshop hosted by the ECRYPT Network of Excellence will be held in Leuven, Belgium. The goal of the SASC 2006 workshop is to gather researchers working in the area of stream cipher analysis and design.
  The workshop is an activity of ECRYPT's STVL - Symmetric Techniques Virtual Lab. In particular, the workshop is focused on researchers participating in ECRYPT's eSTREAM project, in which 34 new stream cipher proposals are currently evaluated with respect to their security and performance.
  The main goal of this workshop is to give participants the opportunity to give talks, present their research and discuss various aspects of the eSTREAM project. You can find the site for this workshop here.

• eSTREAM Software Performance testing is online (November 7th, 2005)

  One of the requirements imposed on all eSTREAM stream cipher submissions was that they should demonstrate the potential to be superior to the AES in at least one significant aspect. An aspect which is particularly significant for Profile I candidates is software performance. Software performance can be measured in many different ways, and in order to make comparisons as fair as possible, eSTREAM has decided to develop a testing framework. This testing framework and documentation is now available here .
  The framework has two objectives:
  1. assuring that all stream cipher proposals are submitted to the same tests under the same circumstances
  2. automating the test procedure as much as possible such that new optimized implementations can be included and tested with as little effort as possible.
  We kindly invite you to take a look at the testing framework, documentation and first performance results, and appreciate your feedback and collaboration in the performance measurement effort. Please direct any questions to estreamtesting@ecrypt.eu.org .
  We refer to the eSTREAM Update 1, Section 4 for more explanations about the aim of the software performance testing. Please note that we have extended the deadline to submit optimized code until January 6th, 2006.
