| Summary: | A hash function usually has two main components: a compression function or
permutation function and mode of operation. In this paper, we propose a new concrete
novel design of a permutation based hash functions called MOIM. MOIM is based on
concatenating two parallel fast wide pipe constructions as a mode of operation designed
by Nandi and Paul, and presented at Indocrypt 2010 where the size of the internal state
is significantly larger than the size of the output. And the permutations functions used
in MOIM are inspired from the SHA-3 finalist Grøstl hash function which is originally
inspired from Rijndael design (AES). As a consequence there is a very strong confusion
and diffusion in MOIM. Also, we show that MOIM resists all the generic attacks and
Joux attack in two defense security levels. |
