The MTUHash takes a message

$($

to be hashed

$)$

$$as input and outputs a fixed

$3$

$2$

$-$

bit value. Note that

the output with

$3$

$2$

$-$

bit length is not very secure in practice. Here is a simplification of the problem.

We assume that the input message has a fixed length of

$3$

$2$

$$bits$.$ It is a simplification of the problem.
