Abstract: It is one of the most classical problems in modern cryptology how to
construct a hash function using block ciphers. Many schemes have been
proposed and some of them are specified in ISO/IEC 10118-2. Recently,
it also attracts some interests as an approach to construct a hash
function in resource-constrained environments. In this talk, a new
scheme is proposed to construct a hash function using an MMO-type
double-block compression function, and its security is evaluated in
terms of provable security. Some comparisons are also made between
the proposed scheme and existing schemes.
