http://ed25519.cr.yp.to/software.html includes a chart and pointers. Pretty much the entirety of the ECC patent FUD comes from patents that * have expired by now (Schnorr in 2008, Crandall in 2011, etc.) and * never claimed in the first place to cover anything that we're actually doing in real-world ECC. The only exception I'm aware of is the point-compression patent 6141420, but there's very solid prior art for that one, and in any case it'll expire in July 2014. ---D. J.
