  Let $X$ be a smooth hypersurface $X$ of degree $d\geq4$ in a projective space
$\mathbb P^{n+1}$. We consider a projection of $X$ from $p\in\mathbb P^{n+1}$
to a plane $H\cong\mathbb P^n$. This projection induces an extension of
function fields $\mathbb C(X)/\mathbb C(\mathbb P^n)$. The point $p$ is called
a Galois point if the extension is Galois. In this paper, we will give a
necessary and sufficient conditions for $X$ to have Galois points by using
linear automorphisms.
