In DSA algorithm you are given with $p=37$ choose appropriate $p,h=3$ and choose $x=$ last digit of

your registration number $($if not valid then choose $x=5)$ and choose $k=$ last digit of your registration

number $($if not valid then $k=7)$

And $H(M)=5.$ Now calculate the signature $\{r,s\}$ and also verify these signatures on the receiver

side?
