Supersingular Isogeny Key Exchange broken? Found this report detailing a quantum algorithm for computing isogenies
between supersingular elliptic curves.

http://cacr.uwaterloo.ca/techreports/2014/cacr2014-24.pdf

with the quote "recommendation
to avoid using base curves defined over Fp in De Feo-Jao-Plut type
schemes".

Is it correct then that 'Supersingular Isogeny Key Exchange' of De Feo is broken?

If so, as this is a fast moving field, are there any recommendations for alternate post quantum key exchange with reasonably good key size and speed?

Thank you.
Sorry I will have to answer my own question.   

I received a mail from Luca De Feo a moment ago.
"Nope, I discussed this at length with Jean-François Biasse, and we couldn't find a way to apply this kind of attack to SSIKE."

I'll leave this question around for reference for the next person who wonders.
