Anil - There are a lot of legal issues surrounding the use of Certicom patented ECC code. One of the things that happened a couple of IETF meetings ago was that Certicom signed a letter allowing the use of some of their patents for things like TLS. However, there are a number of legal requirements attached, including the listing/displaying of the Certicom patents on splash screens or on the hardware device depending on the type of implementation. I would strongly urge you to have a lawyer research these licensing agreements and then research (with you) what additional patents might be involved (for instance Certicom has a patent on having an ECC public key in an X.509 cert signed using RSA) in your product. While ECC is a marvelous technology, there is a large minefield that still needs to be mapped. Bob Bell

I saw that Sun systems has donated the the ECCcode to OpenSSL. Also I saw that Certicom has held 130 patents in ECC area and finally NSA has licensed that code. Suppose if I download the code from the OpenSSL and try to develop a product using the OpenSSL ECC code, does it violate any patent issue with certicom? Can anybody share any experience or information about this? Thanks for support. -Anil _____ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.
