The hash function HAVAL
is a well known Merkle-Damg\r{a}rd hash function such as MD4 and MD5.
It has three variants, $3$-, $4$- and $5$-pass HAVAL.
On $3$-pass HAVAL,
the best known attack finds a collision pair
with $2^{7}$ computations of the compression function.
To find $k$ collision pairs,
it requires $2^{7}k$ computations.
In this paper,
we present a better collision attack on $3$-pass HAVAL,
which can find $k$ collision pairs with only $2k+33$ computations.
Further,
our message differential is different from the previous ones.
It is important to find collisions for different message differentials. |
