I'm at the Crypto 2003 conference, and a paper was just presented on an attack against HFE based cryptosystems, including Quartz. Apparently Quartz only has 2^62 security rather than 2^80 security as originally claimed. But for software registration 2^62 is probably acceptable. BTW, is anyone else on this list at the conference?
