Not sure why this first appeared as blank, sorry about that. I've pasted the text below for a 2nd try: > -----Original Message----- > From: Dan Brown RFC 3979 "strongly encourages" a "preliminary disclosure" for any technology being "seriously considered". I am not sure which of this RG list or if http://www.ietf.org/ipr/file-disclosure.html is the correct place to make such a preliminary disclosure. The RG list is more convenient for me, so here it goes. Upon review today, I noticed that US Patent 6,563,928 B1, Claim 59, supported in interpretation by reference to the patent specification's Column 5, lines 37-46 (which describes the case Zp*, but carries over, per the claim, to the elliptic curve case) seems to anticipate some aspects of twist security that are, arguably, exactly those aspects critical to avoiding an attack. As such, the patent holder may try to assert this against implementations of twist security. Accordingly, I am disclosing this possibility. Best regards, Dan
