### Does a list of discrete log equations reveal information?

A little notation: we'll write $\mathrm{DLOG}(h,y)$ for a magic, general purpose discrete logarithm solver that returns $z$ where $h^z=y$ in our group of order $q$ and $\mathrm{DH}(h,c,d)$ for a magic,...

### If a curve $E/\mathbb{F}_q$ is secure, what can be said about $E/\mathbb{F}_{q^2}$
If you can solve DLP in $E(\mathbb F_{p^2})$, you can solve DLP in $E(\mathbb F_p)$. The "proof" is simply that $E(\mathbb F_p)\subseteq E(\mathbb F_{p^2})$. What's more, the subgroup of \$E(\...
