CRYPTREC

CRYPTREC ( Cryptography Research and Evaluation Committee) was established by the Japanese government to assess cryptographic techniques for public or industrial use and recommend. It is comparable in many areas with the EU and the process for finding an Advanced Encryption Standard of NIST in the USA NESSIE project.

Comparison with NESSIE

The recommended algorithms in the selection of NESSIE and the draft proposals of CRYPTREC overlap in part and disagree in others. Both projects employ some of the best cryptographers and actual ( or perceived ) conflict in the selections should be thoroughly investigated. So CRYPTREC recommends, for example, some 64- bit block ciphers and NESSIE no, but in contrast to NESSIE CRYPTREC had to take into account the order, existing standards and practices.

Similar differences in the task pane justify that CRYPTREC with RC4 stream cipher recommend at least one ( and NESSIE Remarkably, none of the investigated within the framework of the project). RC4 is often used in the SSL / TLS protocol; nevertheless CRYPTREC recommends its use only with 128 -bit keys.

The same applies to CRYPTRECs intake of 160-bit cryptographic hash functions, despite the recommendation to avoid these new systems. CRYPTREC was exceptionally careful to examine variations and modifications of the techniques, which partly resulted in detailed recommendations.

Background and sponsors

CRYPTREC has employees from Japanese universities, industry and government. As of May 2000, several agencies were the methods and techniques for implementing an " e- government" under investigation are summarized. It is sponsored by the

  • Ministry of Economy, Trade and Industry
  • Ministry of Public Management, Home Affairs and Posts and Telecommunications
  • Of information technology Promotion Agency

Recommended techniques

In June 2000 and August 2001, the committee called for submission of techniques and received 63 proposals. In addition, elsewhere were recommended and / or included as ( for Japan) important one techniques.

After 2001, 2002 and 2003 published progress reports a proposal draft was published in August 2003.
