Thank you for improving the random oracle article.
I thought a 4-round Feistel construction was enough -- possibly I misread the Craig Gentry and Zulfikar Ramzan reference in that article.
So I am glad that you added a reference. So now I know that 4 rounds are inadequate, but fourteen rounds are sufficient. (Perhaps someday I will read that reference carefully enough to understand: Why are 4 rounds are inadequate, but fourteen rounds are sufficient ?).
