Interesting paper (the algorithm is on page 8):
http://citeseerx.ist.psu.edu/viewdoc/download;jsessionid=F2BD39FF5C24221B424E12D9ED4E68B7?doi=10.1.1.43.4155&rep=rep1&type=pdf

The reason I suggested SHA-1 is because we already have SHA-1 code involved (in fact, we even have a bunch of precalculated SHA-1s available to us) and performance matters not one iota in this application.
