It was presented in "A key recovery attack on discrete log-based schemes using
a prime order subgroup" at Crypto'97, see the link (unfortunately only to a PS
file) at http://dasan.sejong.ac.kr/~chlim/english_pub.html.  There's a PDF-ised
version available via Citeseer at 
http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.44.5296&rep=rep1&type=pdf.
