The 128-bit Blockcipher


CLEFIA is proposed to CRYPTREC (Application for Cryptographic Techniques towards the Revision of the e-Government Recommended Ciphers List).

CRYPTREC is evaluating security and implementations of the applied cryptographic techniques towards the revision of the e-Government Recommended Ciphers List.

On March 2, 2011, CRYPTREC Symposium 2011 was held and it was presented that CLEFIA proceeds to the 2nd evaluation phase.


  • CRYPTREC (Cryptography Research and Evaluation Committees)
    CRYPTREC is a project to evaluate and monitor the security of Japanese e-Government recommended ciphers, as well as to examine the establishment of evaluation criteria for cryptographic modules. For more information, see the CRYPTREC home page.Open in new window
