I was putting together a memo on licensing needs for IPSec products, and looked in the various drafts for guidance. From what I understand, IETF standards-track documents are supposed to contain a section discussing any patent issues that may pertain to the technology in question. A number of the transform specs contain such sections (e.g., DES and IDEA). Somewhat to my surprise, the ISAKMP/Oakley documents do not. I also looked in other places (specifically, Scheier) for input. It mentioned the well-known fact that RSA is subject to patents and licenses. No confusion there. Scheier also discussed the situation for DSS. As I read it, it sounds like the patent situation there is muddled. In particular, he mentions a U.S. Government patent (D. Kravitz) supposedly generally licensed at no cost -- but also mentions that claims have been made that the Schorr patent applies as well. Question: Does anyone have any further insight on this topic? And could this be added to the document? paul -- !----------------------------------------------------------------------- ! Paul Koning, NI1D, C-24183 !
