We would like to announce:
- A new cryptographic primitive SBC (special block cipher)
- A family of hash functions SNMAC as candidates for hash
functions of
new generation
The paper "A New Concept of Hash Functions SNMAC Using
a Special Block
Cipher and NMAC/HMAC Constructions" was sent to
EUROCRYPT 2007. Its
extended version is available as IACR eprint Report
2006/376, http://eprint.ia
cr.org/2006/376.pdf.
We ought to publish concrete instances of SBC (special block
cipher DN)
and of SNMAC (hash function HDN) on SNMAC homepage as soon
as it will
be possible (waiting for an approval of the publication).
SNMAC homepage:
http://cryptography.hyperlink.cz/SNMAC/SNMAC_EN.html
The paper contains also an explanation why we need the new
cryptographic
primitive for hash functions. It also describes the
procedure, which
led to proposals of SBC and SNMAC. We hope that the new
concept will
be discussed.
