We obtain nontrivial estimates of quadratic character sums of division polynomials ${{\text{ }\!\!\psi\!\!\text{ }}_{n}}\left( P \right)$, $n\,=\,1,\,2,\,\ldots $ , evaluated at a given point $P$ on an elliptic curve over a finite field of $q$ elements. Our bounds are nontrivial if the order of $P$ is at least ${{q}^{{}^{1}/{}_{2+\varepsilon }}}$ for some fixed $\varepsilon \,>\,0$. This work is motivated by an open question about statistical indistinguishability of some cryptographically relevant sequences that was recently brought up by K. Lauter and the second author.
