The Weil pairing is a great big hole in our usual arguments that most 
elliptic curves are strong.

The usual arguments that it is likely to be hard to solve the discrete 
log problem for elliptic curves do not apply to an elliptic curve with a 
Weil pairing.

Samuel Neves sounds like he understands enough maths to discern what 
qualifies an elliptic curve with a Weil pairing to be strong, but I do not.
