IPR Situation IPR has been a big problem for PAKE algorithms Two known basic algorithms Both heavily IPR encumbered IPR holders have been unwilling to release DoCoMo believes OPAKE is uncovered by previous IPR But DoCoMo has filed for IPR on OPAKE (sorry). However, DoCoMo’s default IETF IPR policy is RFC 1822 (Photuris) if IPR affects interoperability Royality-free release if IPR is used in an Internet Standard Nonretaliation Decision for release hasn’t been made on OPAKE yet Not even a draft on it, so premature We will attempt to get it released if the WG is interested |
