Unfortunately this space is littered with patents and it is essentially impossible to know if this scheme is violating some existing patents.
My guess is that *it probably does* but that these patents haven't been subjected to a formal trial. The latter is important because in the US (at least) you can get a patent on almost anything these days. I'm not worried about giants like Microsoft since they would just lose by suing Open Source, but small companies that mainly trade in IPR could make things less fun. It is possible that the scheme violates a bunch of Certicom's 400+ ECC patents but I don't have the time, money, knowledge, or motivation for checking that either. According to TCG they offer RAND conditions but what does that mean in terms of money? Once upon a time (1998) I did actually file a few patent applications myself but nowadays I'm convinced that software (method) patents is a very bad idea that only stifles progress...
